Srixon Z-Star Diamond Golf Ball
Srixon — Srixon Z-Star Diamond Golf Ball · By Andy · Nov 20, 2025
The spin-obsessed middle child of Srixon's tour lineup -- now with a softer feel, a thicker urethane cover, and greenside performance that punches well above its price point.
The Big Picture
The Srixon Z-Star Diamond occupies a specific and valuable niche in the premium golf ball market. The standard Z-Star is the soft-feel, higher-spin option. The Z-Star XV is the firmer, lower-spin distance ball. The Diamond was designed to split the difference -- offering the launch characteristics of the XV with more greenside control, all wrapped in a three-piece construction that keeps the price below many four-piece competitors.
For the 2025 model, Srixon reengineered the core to be softer than its predecessor, addressing the most common complaint about the original Diamond: that it felt too harsh around the greens. The thicker urethane cover now features Srixon's Spin Skin with SeRM technology, a proprietary coating designed to increase friction between the ball and your grooves at impact. The 338-dimple Speed Dimple pattern rounds out the construction, engineered to reduce drag and improve flight stability, particularly in wind.
This is a ball built for players who want to hold greens with mid and short irons without giving up too much distance off the tee. It is best suited for golfers with moderate-to-fast swing speeds -- Srixon rates it for driver speeds of 90+ mph with a compression around 102. At roughly $47-50 per dozen, it undercuts the Titleist Pro V1 family by a meaningful margin while delivering genuinely competitive performance.
Sound & Feel
The 2025 Z-Star Diamond feels noticeably softer than its predecessor, and that improvement was apparent from the first chip shot. The older version had a harshness around the greens that made it feel like a distance ball pretending to be a tour ball. This version does not have that problem. Wedge shots and chips produce a responsive, controlled feel -- not pillowy soft like a two-piece distance ball, but genuinely pleasant. You get clear feedback on strike quality without any sting.

Off the putter face, the Diamond sits on the firmer side of the spectrum. It has an audible click that is not loud but is definitely present. If you are used to a very soft putting feel, you will notice the difference. Personally, I found the firmer putter response helpful for pace control -- you can feel the ball leave the face distinctly, which makes it easier to develop a consistent stroke speed.
With irons and driver, the feel is solid and lively. There is no sensation of the ball sitting on the face -- it jumps off with authority, which matches the performance numbers I saw on the launch monitor.
Performance
Ball Speed & Distance
Off the driver, the Z-Star Diamond produced ball speeds around 160 mph in my testing, resulting in carry distances of roughly 271 yards and total distances near 287 yards. Those are competitive numbers, though spin crept up to about 2,800 rpm off the driver -- a touch high for maximizing carry distance. The result is a flight that lands a bit steeper than a lower-spinning ball, which means slightly less rollout but more control on the landing.
The 7-iron numbers told a more nuanced story. Ball speeds of 116 mph produced carry distances of 159 yards and totals around 167 yards, accompanied by spin rates near 6,700 rpm. Those are outstanding spin numbers for approach shot control, but the distance was shorter than several competing premium balls I have tested recently. This is the Diamond's fundamental trade-off: you gain greenside control at the expense of some iron distance. For players who prioritize stopping power on approaches, that is a trade worth making.
Launch & Spin
The Z-Star Diamond produces a low-to-mid launch with high spin on iron and wedge shots. With a 56-degree wedge, I recorded spin rates around 7,300-7,600 rpm on partial shots, which is excellent for check-and-stop performance around the greens. Full wedge shots produced even higher spin, approaching 9,700 rpm with clean contact.
Off the tee, the ball launches on a penetrating trajectory. The 338-dimple pattern helps maintain stability in wind, and the lower launch window means the Diamond holds its line better in breezy conditions than some higher-flying competitors. The spin profile off the driver is moderate -- not low enough to call this a distance ball, but controlled enough that it does not balloon.
This spin distribution -- lower off the tee, progressively higher through the irons, and very high around the greens -- is exactly what tour-level players look for in a premium ball.
Dispersion & Shot Shape
The Diamond performed consistently in terms of shot shaping. I was able to work the ball both ways with mid-irons without difficulty, and the higher spin rates on approach shots meant I could attack pins with confidence, knowing the ball would check rather than release through the green. From wet lies and damp rough, the urethane cover maintained its grip and produced reliable spin, though the numbers naturally dropped as they do with any ball in those conditions.
MSRP: ~$50/dozen
Verdict
The 2025 Srixon Z-Star Diamond is a meaningfully improved golf ball that successfully bridges the gap between distance and control. The softer feel around the greens addresses the biggest weakness of its predecessor, and the spin performance with wedges and short irons is genuinely impressive. It is not the longest ball off the tee, and slower swing speed players may not compress it enough to see its full potential, but for golfers with the speed to match, it delivers tour-level performance at a price that makes the premium ball category more accessible.
Strengths: Outstanding greenside spin and control. Noticeably softer feel than the previous generation. Stable, penetrating flight in wind. Excellent value compared to other premium three-piece balls. Strong compression consistency across the box.
Weaknesses: Iron distances were shorter than some competitors -- you trade length for spin. Driver spin at 2,800 rpm is a touch high for maximum carry. Not ideal for slower swing speeds below 90 mph.
Who it is for: Mid-to-low handicappers who prioritize approach shot control and greenside spin over raw distance. Strong iron players who want the ball to stop where it lands. Golfers with moderate-to-fast swing speeds looking for a premium ball that will not break the bank. If you are a good ball striker who values feel and precision, the Z-Star Diamond is one of the best values in premium golf balls.
