Z-Star Diamond slots between the standard Z-Star and the firmer XV, using the same FastLayer DG Core 2.0 platform with a firmness and compression tuned to sit in between its two siblings. MyGolfSpy's 2025 ball test found it the most consistent of the three Srixon tour balls across its testing, with both XV and Diamond finishing near the top of the field for driver distance.
A middle-ground feel between Z-Star and Z-Star XV — firmer than the standard Z-Star off the tee but not as extreme as the XV, with solid greenside spin from the Spin Skin+ cover.
A fitting-cart option for players who found the standard Z-Star too soft and the XV too firm; a reasonable one-ball answer across the bag for mid-to-fast swing speeds.
The newest and lowest-volume of Srixon's three tour balls, so expect thinner recovered-ball supply than Z-Star or Z-Star XV for now.
Reading is one thing — feeling it off the face is another. Book a bay and hit a sleeve before you buy anywhere.
