Srixon Z-STAR DIAMOND Golf Balls Review
The underrated middle Z-STAR: fast and low-spinning off the driver, with extra spin on long and mid irons and full tour-level wedge control.
What we like
- Blends Z-STAR greenside control with long-game distance
- Srixon says it adds spin on long and mid iron shots
- Urethane cover with Spin Skin+ for wedge spin
- $54.99 per dozen, the same as Z-STAR and Z-STAR XV
What to weigh
- Firm-leaning feel, so soft-feel players may prefer Z-STAR
- Best for golfers with enough speed to compress it
- Less known than the other Z-STAR models
- Urethane still scuffs

Quick answer
Z-STAR DIAMOND sits between Srixon’s softer Z-STAR and faster Z-STAR XV. Srixon says it blends greenside control and long-game distance while adding more spin on long and mid iron shots. Independent testing supports that profile: it measures at roughly 93 compression, is widely regarded as one of the most underrated tour balls, and is fast and low-spinning with the driver while staying controllable with irons.
What is inside
- Thin urethane cover with biomass and Spin Skin+ coating for greenside spin, with stronger paint for better dirt resistance.
- FastLayer DG Core 2.0: soft in the center and firmer toward the edge, tuned for feel, iron spin, and ball speed.
- 338 Speed Dimple Pattern for less drag, more lift, and a straight flight in wind.
Z-STAR vs DIAMOND vs XV
- Z-STAR: softest feel and most greenside spin.
- Z-STAR DIAMOND: low driver spin plus extra iron spin.
- Z-STAR XV: most speed and distance, and the firmest feel.

Verdict
Z-STAR DIAMOND deserves more attention. If you hit the ball far enough but struggle to hold greens with longer irons, it may be the best Srixon ball for your game.
