Compression
How soft the ball feels. Lower numbers (70–80) compress easier and help slower swings get distance. Higher (90+) rewards faster swings.
Cover
Surlyn is tough and cheap — great for distance and durability. Urethane is softer and grips wedges for more spin around the green.
Layers
2-piece: simple, long, straight. 3-piece and 4-piece add layers for more feel and spin control on approach shots.
Trajectory
How high the ball flies. Low = flatter flight with more roll. High = peaks up and lands soft. Mid = balanced.
Spin
Low spin = straighter shots, less curve, more roll. High spin = more control and stopping power on the green (but also magnifies slices/hooks).
Tier
Price bucket. Value = budget-friendly distance balls. Mid = solid all-around. Premium = tour-level spin and feel, costs more per dozen.
Best For
Try a sleeve first — ~$5 for 3 balls before committing to a dozen.

The current-generation Z-Star Diamond (2025 refresh, the ball J.J. Spaun played to win the 2025 U.S. Open), a 3-piece urethane ball with FastLayer DG Core 2.0 (soft center, firm outside), delivering the highest iron, driver, and greenside spin in the Z-Star lineup — a spin-first tour ball for skilled players.
Who It’s For
The Srixon Z-Star Diamond is built for faster swing speeds (105 mph and above). It suits golfers who prioritize high swing speed, tour players, iron control. In the Srixon lineup, the Z-Star Diamond sits softer than the Srixon Marathon.
Feel
With a compression of 93 and a urethane cover, feel is firm and explosive, with a crisp click at impact that fast swingers tend to like.
Spin Profile
Expect the highest driver spin in the Z-Star family — useful if you need the tee shot to hold its line, costly if your drives already balloon. Around the green the wedge flight is low and spinny, 46th of 48 for both 35-yard wedge launch and apex in the robot data, so it skids and grabs rather than dropping in soft.
Trajectory & Construction
A low launch that climbs on spin: in that robot test the driver left the face at 12.5 degrees at 102 mph, 46th of 48, yet peaked 8th-highest in the field. Three pieces: the FastLayer DG Core 2.0 (soft center, firm outside), a mantle and a urethane cover, in the 2025 refresh J.J. Spaun won the U.S. Open with. Works best in warmer conditions.
Price & Value
At $54.99 per dozen it is $3 under a Pro V1x and priced identically to its two Z-Star siblings. You are paying for spin: it out-spun the other two Z-Stars with every club MyGolfSpy tested in 2026.
Buy it if
- You swing 105+ mph and you want maximum spin and stopping power on approach shots.
- You want a tight pattern at speed: driver dispersion at 116 mph ran 46% tighter than its comparison group in the 2026 robot data.
Skip it if
- You want a soft feel. At 93 compression it feels firm, even though firmer balls tended to be faster off the driver at every swing speed in robot testing.
- You want a 7-iron that flies high; it had the second-lowest 7-iron apex of 48 balls in MyGolfSpy’s 2026 robot test.

Frequently Asked Questions
What is the compression of the Srixon Z-Star Diamond golf ball?
The Srixon Z-Star Diamond has a compression of about 93, which puts it in the high-compression range. At 93 it is the middle Z-Star for firmness, softer than the XV and firmer than the standard Z-Star, with the crisp strike fast swingers tend to prefer. It is one of several specs the BallCaddie fitting quiz weighs against your swing speed, usual miss, feel preference and budget.
Who should play the Srixon Z-Star Diamond?
The Srixon Z-Star Diamond is built for faster swing speeds (105 mph and above). It suits golfers who prioritize high swing speed, tour players, iron control.
What swing speed is the Srixon Z-Star Diamond designed for?
Srixon aims it at faster swings, and its distance holds up there: driver carry ranked 18th of 48 at 116 mph in MyGolfSpy’s 2026 robot test, its best of the three speeds. Slower swings compress it fine; what they get is the most 7-iron spin of any ball in that test, which is control or lost yards depending on your game.
Does the Srixon Z-Star Diamond have high greenside spin?
Yes. It is Srixon’s highest-spinning Z-Star, and in MyGolfSpy’s 2026 robot test it ranked top three of 48 for spin with the driver, the 7-iron and the 35-yard wedge.
Is the Srixon Z-Star Diamond good in cold weather?
Not especially. At 93 it is firm, and none of the three Z-Stars is a ball we flag as cold-weather suitable.
How much does the Srixon Z-Star Diamond cost?
MSRP is $54.99 per dozen.
