Roto Grip Magic Gem Bowling Ball

(23 reviews) Write a Review


Given the overwhelming success of the GEM and Exotic GEM around the globe, we felt it was important to add another viable reaction to this series of balls. So with that direction in mind, we went to work testing various coverstock materials and ultimately circled back to the often imitated, never duplicated MicroTrax material which features nanoparticles mixed evenly throughout the entire ball just like the solid and the pearl before it.

However, this go round we opted to go down the avenue of hybrid in order to compliment both the solid and the pearl. So with that, we tested all the various combinations of hybrid, and in the end, the 2pt pearl / 1pt solid presented the most performance while complimenting both the GEM and Exotic GEM without overlapping either of them.

  • A oil monster

    Posted by Pierre-Luc Larouche on Dec 1st 2023

    If you search a oil monster, the Roto Grip Magic Gem is for you !! Also for people that have less rotation it can help you to make a good reaction. For me, the Magic Gem have a really nice round react. It's perfect for the sport patern who have a lot oil on it or at a begining of a league night for game 1 and sometimes 2. It's no doubt, the most agressive ball on m bag. It's correctly replace the 900Global reality. I really love to play with !! #ownit !!!

    The Roto Grip Magic Gem is a powerhouse on the lanes, boasting a perfect blend of power, continuity, and aggression. Whether you're a seasoned competitor or a casual bowler looking to up your game, the Magic Gem is a worthy investment. Its ability to deliver a powerful punch with a continuous roll and an aggressive hook makes it a standout choice for bowlers who demand nothing but the best from their equipment. Unleash the magic, and watch your scores soar. #SquadRG MY SPECS: PAP: 4 7/8 R 7/8 UP REV: 350 MPH: 15 @PINS LAYOUT: 4 5/8 X 3 5/8 X 1 1/2 VLS Test Pattern: 42' THS This a great ball for the speed dominant bowler who love to play the track and need a ball to slow down at the breakpoint. Tweeners will need cover adjustments and hand position changes to maximize play. The OOB 2000 Abralon was to early for me for my THS. Changed surface to 5000 CTD pad polished resulting in cleaner through the fronts to retain energy at the pins. Same familiar shapes as my OG Gem and Exotic with the same big backend flip but controllable . Need that big asymmetrical hybrid, pick up a Magic Gem at your local SPI VIP Proshop today. #Stormnation #SquadRG #GoGlobal

    Roto Grip Magic Gem Coverstock: 2000 Grit MicroTrax™ Hybrid Reactive Weight Block: Defiant™ LRG Core (Asymmetrical) Color: Citrine/Rhodonite/Jet Review: The GEM line has continued the success of one of Roto Grips greatest lines of all time in the Defiant series. The original Gem and the Exotic Gem have been great additions to the line and have continued the tradition of a strong asymmetric ball that will not be uncontrollable. The Magic Gem is another addition to that tradition. Out of box I felt this ball was just as strong as the original Gem, but the hybrid cover stock gave the ball more shape at the mid-lane rather than earlier or later on the lanes like the other iterations of the Gem did. Besides being a great overall ball, the shelf appeal has been able to makes sales on its own. This ball really pops when going down the lane and really is a unique ball when going down the lane.

    The Magic Gem is the latest addition to the HP4 line at Roto Grip. After the previous, extremely successful releases like the original and Exotic Gem, the Magic had big shoes to fill. The Magic Gem is different than the previous releases because of its coverstock. The original Gem provided a solid coverstock while the Exotic Gem provided a pearl coverstock. Naturally, the Magic fits right in the middle providing a hybrid coverstock while using the same Defiant LRG core. With an RG of 2.47, differential of .053, and PSA of .016, those numbers indicate a ball that wants to read the front part of the lane, dig hard in the mid-lane, and change direction at a moderate level into the pin deck. The hybrid coverstock will create more length than the original Gem, but after throwing the Magic on several surfaces and conditions, I see the Magic wanting to dig similarly to the original Gem. I’ve drilled one so far and think it rolls great. It’s mapped out as 5.5 x 4 x 3. This puts the pin in-between my bridge and middle finger and the CG is just to the right of my thumb. I’ve had the most success with the Magic Gem when I’ve had to keep my angles tighter and when I need something to pick up, but not change direction super hard down lane. I’ve found a ton of consistency with how it rolls and goes through the pins. The Magic Gem can be extremely useful because I think it’s different enough compared to the other balls in the line that it makes complete sense to drill.

    Roto Grip Magic Gem Layout: 4.5 x 5 x 2 Storm Pin Buffer Layout Rev Rate: 325 rpm, 7 degree of axis tilt, 40 degree of axis rotation Testing information: 41 foot THS (medium to light volume) Bowling Center: Fulton Bowling Center Kegel Machine – Brunswick Anvilane The Roto Grip Magic Gem utilizes the MicroTrax hybrid coverstock and the Defiant LRG weight block. The speed dominant or low rev players are going to love this one. The design of the Magic Gem was to fit between the Gem and Exotic Gem. I think this was accomplished but the Magic Gem is closer to the Gem, which isn’t a bad thing. I will use the Magic Gem on long oil patterns and heavier oil patterns. This ball will fill my No. 1 (first ball) slot in my tournament bag. I don’t have my Gem anymore so the Magic Gem came into my life at the right time.

    Orientation: Right Handed Rev Rate: 400 RPM Speed: 16-17 MPH PAP: 4 ½ over and ½ up Location: Enterprise Park Lanes, Springfield MO Pattern: High Volume THS VLS Layout: Layout 1: 5 x 4 x 2 ½ (pin above bridge) Layout 2: 4 ½ x 4 x 4 1/8 (pin below bridge) The Magic Gem is the strongest Gem in the back part of the lane ever! Think early jerk. The Gem is early and slow. The Exotic is cleaner and snappy. The Magic Gem hybrid version is earlier than the Exotic by a good deal and WAY more on the backend than the OG Gem. Honestly it was hard for me to keep it online unless I threw the ball pretty hard. If you want to HOOK the ball I honestly can’t think of a ball that hooks more overall for me. If you don’t have oil or ball speed, BEWARE! This is a ton of HOOOOOK.

    The third release in the Gem line combines the best of the two previous releases. The Magic Gem has the same Defiant Asymmetric cover as the others, but the Magic is wrapped in MicroTrax Hybrid Reactive coverstock finished at 2000 grit abralon. The 15-pound version has a RG of 2.47, a differential of .053, and an intermediate diff of .016. Drilled at 5x4x2 (pin above bridge for me), this ball is a monster. It has almost as much total hook as the original Gem, but the motion is very different. The Magic Gem’s reaction is more delayed than the original. It pushes a good 3-4 feet further down the lane before it starts to read the lane. The backend motion is much stronger than the original Gem. This ball is the perfect complement to the original Gem. Once the original is starting to burn up a little too soon, that is the time to go to the Magic Gem. The Magic needs a good amount of oil to be effective, but there is very little quit on the backend even when your angles are pretty open. In my opinion, the Magic is the most versatile of the three Gems.

And what makes the Magic Gem so magical? Roto Grip has wrapped the MicroTrax Hybrid Reactive coverstock around the proven Defiant LRG Core, making the Magic Gem a predictable pin-crushing rolling machine. So, let’s take a closer look at what makes the Magic Gem an excellent choice for your arsenal. The LRG Core has been the heartbeat of Roto Grip’s Gem line and continues its pumping success inside the Magic Gem. Being a straighter low-rev player, I liked how the Defiant LRG had a smooth and continuous roll in the mid-lane yet stood up with authority when it turned off the pattern. And rather than being lazy and slow to make its decision like large asymmetrical cores tend to do, the Defiant LRG Core makes a decisive and predictable motion to the pocket and still retains a powerful punch through the pins. And being a large asymmetrical core, I could count on the Defiant LRG Core to have a strong and continuous roll through the pins without the deflection I tend to see because of my slower rev rate. So, if you are a down-and-in player like me, you can count on the Defiant LRG to kick out those troubled corner pins we tend to see and keep your game in play when you need it most. The Hybrid MicroTrax Coverstock is an excellent choice for straighter, low-rev players like me. The two-part Pearl and one-part solid Hybrid mixture brings a combination of traction and smoothness that is ideal for players like me. Unlike some solid coverstocks that tend to roll out and lose energy through the pocket, the MicroTrax Hybrid has the right amount of solid to get you through the heads without being overly aggressive, which causes the ball to burn up energy. And unlike pearl coverstocks that go far too long before they make their turn, causing you to 2-8-10, the two-part Pearl in the MicroTrax Hybrid coverstock has smooth traction when it finds friction and blends the transition of wet/dry without being jumpy or erratic off the pattern. So, if you are a straighter, down–and–in bowler like me, you can count on the MicroTrax Hybrid Cover to deliver a predictable and stable motion all night. In closing, the Magic Gem is an excellent new release by Roto Grip! And with the Defiant LRG Core and the MicroTrax Hybrid Coverstock combination, the Magic Gem is perfect for any down-and-in low-rev player like me. So, stop into your local Storm VIP Pro Shop and have the Roto Grip Magic Gem ready to roll for tonight’s league. Your game, scores, and team will be glad you did!

    Roto Grip Magic Gem Coverstock: 2000 Grit MicroTrax™ Hybrid Reactive Weight Block: Defiant™ LRG Core (Asymmetrical) Color: Citrine/Rhodonite/Jet Review: The Gem series has been a home run for that first out of bag bowling ball and not to mention the awesome shelf appeal! If you love those bowling balls that like to move this will not disappoint. Our style: tweener, 350-375 revs, 16.5mph, layout of choice is 4x4x2 (pin is above bridge). We really like this ball for fresh tournament and house patterns. We often find ourselves beginning with this piece in game 1 and transitioning to something a little smoother down lane in the later part of game 2 and game 3. This ball may not be as versatile as some of the other SPI asym bowling balls but it must not be overlooked for its power on the fresh. It really is a true Gem. This may be more of a niche piece but it is definitely worth checking out at a local matchmaker to see if it fills that Magic gap in your arsenal!

    Roto Grip Magic Gem Coverstock: MicroTrax Hybrid Reactive Finish: 2000-grit Abralon Core: Defiant LRG Core RG: 2.47, Diff: 0.053, PSA: 0.016 (15 lb.) VLS Layout: 5 x 5 x 2 Dual Angle Layout: 65 x 5 x 30 PAP: 5 3/16” right x 5/8” up Rev rate: 400 rpm Average speed: 16.5 mph Location: Prairie Lanes, Sun Prairie WI Pattern: Medium volume THS The Roto Grip Magic Gem is the newest addition to the Gem series, this time featuring the hybrid MicroTrax cover that’s 2-parts pearl and 1-part solid and wrapped around the ever-familiar Defiant LRG core. The intent with this release was to compliment the reactions of the original Gem and Exotic Gem by slotting between those two balls – a little cleaner through the fronts than the Gem but with more midlane read than the Exotic Gem. After my first few shots, it was clearly evident that the Magic Gem is a very aggressive ball that is more continuous downlane than the Gem, and thanks to the 2000-grit Abralon hybrid cover it picks up and reads the body of the oil pattern better than the Exotic. I threw the Magic Gem after the Saturday morning junior league, and even though there was a fair amount of carry down from the kiddos, I was still forced to move further left than expected to find enough oil to get the ball down the lane. To my eye, the Magic Gem creates a strong and powerful reaction that’s more reminiscent of the Gem, but the Magic manages to be a bit cleaner and creates more downlane motion that better drives through the pins. The Exotic Gem or Clone would be a good option to ball down to when the Magic Gem becomes too strong. I expect the Magic Gem to be a great ball for blending out the over/under reaction you typically see on league house patterns. It’s super strong out of the box, but I suspect it will become more versatile as it lane-shines after a few games or by adjusting the surface with a 3000- or 4000-grit Abralon pad so that it doesn’t dig so hard into the oil. I see the Magic Gem as being my go-to for heavier volume patterns when I need a bit more shape than what the OG Gem is capable of. If you’re looking for a ball with a powerful and aggressive reaction, there’s no need to look further than Magic Gem. Chris Pollentier Storm Pro Shop Staff #StormNation #SquadRG

    The Roto Grip Magic Gem is the newest HP4 ball to hit the SPI line. The Magic Gem features the MicroTrax hybrid cover that’s wrapped in the same Defiant LRG core that was featured in the GEM and Exotic before. The Magic Gem for me is the perfect step down from the original when I need slightly less traction and more overall shape. The Magic Gem is the perfect compliment to the Reality, being slightly cleaner and faster. Review Video: (

The original Gem is noted as the earliest rolling ball at the current time. The two part pearl one part solid makes up the Magic Gem. Although the Magic Gem will provide the bowler extra length, you can expect the Magic Gem to also give you more reaction when the ball encounters friction compared to the Gem. Anything you desire in a ball to create hook, more hook, oh and can you say "hook!". This one is for you. You should expect an early continuous, strong reaction. The best part is the Magic Gem will provide continuous lane motion early on, yet provide great control. The Magic Gem achieves some length so the ball does not "hook at your feet" which would have occurred with older generation of bowling balls. The Magic Gem will work best on long, medium and higher volume patterns. If your desire is to stay left before and as the the lanes transition this ball will not disappoint. If you want the biggest, aggressive and most powerful hybrid on the market today in your bag, this is the one! Don't hesitate to try out the Roto Grip Magic Gem today.

    Ball Specs: Roto Grip Magic Gem Micro Trax Hybrid Reactive Asymmetric Defiant LRG Core Finish: 2000 grit Abralon Layout: 3.75 x 4.5 with 1.5 Pin Buffer Bowler Specs: Right Hand. PAP 5” Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at release 17 Review: The Magic Gem is a very aggressive Hybrid at box finish. The Magic Gem is more continuous down lane than the Original Gem due to the fact it is a hybrid so it stores more energy and does not go forward to soon. I do feel the Magic Gem will perform better on a house shot with a smoother, polished surface than box. This ball will need some oil especially up front to roll at its best. I feel that weaker layouts would work best unless a bowler really needs help creating motion because the Magic Gem has a very powerful hook potential out of the box. I have not rolled this ball a lot but I am able to carry lighter off hits with it and solid hits destroy the rack. So far I have only tested the ball at box finish. This ball will be great for the flatter tournament shots or for higher speed or lower rev bowlers. Roto Grip has done an excellent job of placing this ball right between the Original Gem and the Exotic Gem. I am looking forward to getting this ball on some wetter lane conditions to see what it can do. The Magic at box is too strong for the house shots in my area. Summary: The Magic Gem sits right between the Exotic and original Gem in motion. The Balls colors look great as it rolls. If you are looking for a strong Hybrid give the Magic Gem a look.

    Magic Gem: The Magic Gem is the strongest ball I currently have in my bag. We see plenty of overall motion with this ball as it reads the kids very strong and continues very well. This ball is designed for those heavier oil conditions or when they're absolutely walled and you need the ball to get ramped up early to fight those tighter conditions. I see myself using this ball more on sport conditions versus house as I typically need a cleaner reaction on house to blend out the pattern more which provides additional miss room. For those who liked the X3 from Roto Grip you will enjoy the Magic Gem. TNT Infused: The TNT Infused is an excellent benchmark symmetrical ball to throw when the fronts begin to hook early yet provides tons of mid lane read. The Infused will be more usable for most players against the original TNT as it provides much more back end reaction and doesn't see the fronts as early as the original. I have found success using the TNT as a step down off my stronger balls like the Magic Gem, Eternity PI and Xponent. I am a big fan of this ball as it provides plenty of usability when I need to open my angles up on those medium to higher volume patterns. The Infused will be good on varying patterns from house to sport.

    Cover: MICROTRAX™ Hybrid Core: DEFIANT™ LRG Finish: 2000 grit RG: 2.47 Diff: 0.053 Int. Diff: .016 Right-Handed Tweener Speed: 12-13 mph Rev Rate: 315 PAP: 5 1/8 Right 7/8 Up Ball Layout: Pin over Ring 5 12/2 X 4 1/2 X 2 1/2 VLS The New HP4 release from Roto Grip is the Magic Gem. The Gem line has been at the top of the strength charts since they hit the market and the Magic Gem certainly continues that trend. The Defiant LRG core is this time wrapped in a sanded Hybrid version of micro-trax. While the 2k finish gives it some mid-lane teeth the 2part pearl 1 part solid make-up makes this ball continuous. This has been the most usuable of the Gem releases for me personally. Where I felt the first two were pretty conditional for me because of my ball speed, the Magic Gem is very continous. It doesn't lock up and get forward the way the other two did for me so I don't have to have the giant puddle to push it down-lane or the mega hook backends to get it to tip up. I tested the Magic Gem first time out on our house pattern. While the length and Volume of our pattern can make the lanes very tight, the high friction surface in the front of the lane can make the strongest balls tough to use. Magic Gem's reaction seems to give you the best of both worlds, it sees the mid-lane without over-seeing the fronts and it continues through the back-end. I was very impressed with this ball on the fresh as it was great at blending out the lane. It reacted well through the transition and until the lane really burnt up the last game it gave me a predictable motion as I went left. The versatility of the Magic Gem makes it useful for more people. It's strong enough for the rev-challenged and speed dominant players but continuous enough for the people who struggle stay in a ball once the lanes start to transition. I would recommend this ball for pretty much any style of player as a first ball out of the bag.

    Layout: 5 x 3 x 3 Surface: 2000 Abralon The Magic Gem brings back the Defiant LRG Core with the Microtrax Hybrid Coverstock. My initial though with this ball was that it was going to be a slightly more angular Original Gem that could handle oil. When I threw the ball for the first time, it was significantly stronger than I expected. Compared to the original Gem, it was a little more cleaner through the front but had much more continuation. It kept the pins low through the deck which increased my pin carry. I got to test this on a 44ft Typical House Shot and a 42ft 32ml sport pattern. On the House pattern, it was evident that it was very strong. With my higher ball speed and rev rate, it was almost tough to keep the ball in the pocket enough on the fresh as it just was strong in the midlane and continued hard down the lane. It definitely forced me a little deeper on the lane than I wanted to play on the fresh. I typicall slide around 25 with my feet and throw the ball to between 5 and 10 at the breakpoint on the fresh. The Magic Gem made me slide closer to 32 with my feet to see the right shape down lane. To my surprise, it continued so well that I still had no problems striking from that angle. Compared to the original Gem, I was actually straighter with the original due to how much more forward the roll is. I had to give the pocket away with the Magic Gem to have success. As the lanes started to carry down, my ball reaction got better as I could keep my angles a little straighter. I would recommend this ball for the fresh if you have a lot of oil volume or are more speed dominant. If you are a big fan of the original gem and want a more continuous shape, you can get the Magic Gem. The Magic Gem will not give as much angle as the Exotic Gem for comparison's sake. On the 42ft Sport pattern, the higher oil volume put the Magic Gem in its comfort zone. I was able to play the fresh without a problem and still allowed me to play closer to the friction because of the amount of oil. As the pattern broke down, I was able to move more left with my feet and target and again have no issues with continuation. The ball did however, start to go a little bit more forward as I got closer to sliding around 30-35 with my feet and carry suffered to an extent. The Exotic Gem had a much better angle through the pins from this part of the lane. As a higher rev rate bowler, I prefer the Magic Gem for tournaments or where there is heavy oil just due to its overall strength. Those who have slow ball speed or low amounts of oil will struggle with this ball to keep on line. Adam Chase Storm Staff

Diff.: 0.053 Finish: 2000-Grit Abralon Roto Grip’s new Magic Gem is a Hybrid (2/3 Pearl, 1/3 Solid) Asymmetrical piece that is good for Medium-Heavy Volume Patterns. PAP is 5 5/16 R 1 3/16 Up. Rev Rate: 400. Speed: 16.5. Drilled this piece with the Pin above the bridge, CG kicked out 1” from the palm, and the Mass Bias 1/2” to the Right of the Thumb. I threw this piece on a fresh 48’ Shark pattern. Out of Box ball motion started in the mids with smooth Continuous Motion on the backend. Once the pattern broke down, I moved 5-5 Left. It read in the mids with continuous backend. I compared this piece to the Roto Grip Clone and Tour Dynam-X. Clone was 1-1 right and the Tour Dynam-X was 2-2 Right of the Magic Gem. This is a good starting piece on the fresh oil. This ball will be good for all types of bowlers. Check Out the Ball motion Video on my YouTube Page:

    The Magic Gem builds on the predictability and strength of the original Gem. Micro Trax Hybrid features nanoparticles in the cover that create more traction than standard reactive covers. This really makes the Magic Gem stand out because it picks up in the oil just like the original Gem, but the pearl additive in the hybrid coverstock helps the Magic Gem continue through the pins better. The Magic Gem is better at going left to right and creating more angle than the Gem. This ball is the strong control ball that everyone should have in their bag, especially if you have trouble getting the 10 pin out with other big asym balls.

    The newest addition to the Gem family is going to be a great addition. One of the biggest issues that I saw with the Gem was that it was so early and strong that you would lose carry from time to time. The all new Magic Gem has solved this issue in a major way! The Magic Gem is still early and strong, but its biggest attribute is that it is a touch more angular. The angle that this ball creates compared to the OG Gem can be the difference between striking and leaving a flat 10 or weak a 7 pin. The Magic Gem features the same Defiant LRG Core, however, its has the MicroTrax hybrid coverstock compared to the Solid coverstock in the original Gem. I am very pleased with what I have seen from this ball so far and I am sure this ball will get a ton of use from a variety of bowlers, do not hesitate, go out and get yours today.

    The Magic Gem is the newest release in the Gem line. After throwing the Magic Gem, it was much stronger than I expected. It came at 2000-geit but being a hybrid, I was hoping it would not be as strong as the Gem. I was wrong here because it felt like a cleaner Gem with more down lane shape. I think it will be more usable on a house shot than the original Gem, but it is still going to be way too strong for what I can use. As I said before, the Magic Gem is similar strength to the original Gem but is cleaner through the fronts with more shape down lane. Compared to the Exotic, the Magic Gem is closer to the shape but overall stronger. The Magic Gem would be a ball up from the Exotic and one would ball down to the Exotic when the Magic Gem is becoming too strong. The Magic Gem is going to be good for the speed dominant bowlers and on heavier/longer volume house/sport shots. Tobias Myers #RotoGrip

This is featuring the same core found in the Gem but features MicroTrax hybrid this time around. With being a two-part pearl one-part solid cover, this feels similar to the original Gem. If the Gem was too early for your game this ball would be a better fit. The cover takes to surface changes well and will be a great option for the fresh conditions. The Magic Gem is going to be great for the higher ball speed crowd or the lower rev rate that needs that extra help from a ball. For higher rev rates the Magic is going to be a good ball for high volumes and long patterns. The Magic Gem is also a strong step up from the Clone.

    Ben Lapointe PAP: 1 1/4'' up and 4 7/8 over Layout: 5.25x4.25x3 The new Roto Grip Magic Gem, just like it's predecessors is hook in a box. The very strong nature of the Defiant core allows this ball to start up very quickly in the mid lane and the hybrid cover allows it to get done the lane a little further than the original Gem. I found this ball perfectly bridges the gap between the OG and Exotic. I really liked this ball out of the box but when polish is added, you can see just how versatile this piece really is. It does need quite a bit of oil to be at it's most effective, but when there is you can see it digging when it needs to. Go get yours October 20th and don't forget to bowl up a Storm!!

    Roto Grip’s HP4 line has been one of the strongest lines in bowling mostly due to the facts of the Gems. Well the Magic Gem doesn’t disappoint. The Defiant LRG core is wrapped around the 2 parts pearl, 1 part solid Microtrax Hybrid cover. I drilled mine 5.5 x 5 x 5 and WOW, what a first impression. I bowled on a 43 foot 4:1 pattern and the Magic Gem out performed my DNA and Eternity Pi and it was because they were burning up either. The Defiant LRG core is just the strongest core in bowling and paired with this cover I was able to move in and open up the entire lane with this ball. Anyone who though the Gem was a little too strong for them or maybe the Exotic Gem went too long than I would deeply look into the Magic Gem.
