{"product_id":"srixon-z-star-diamond-golf-balls-white-2025","title":"Srixon Z-Star Diamond Golf Balls - 1 Dozen (White)","description":"\u003cp\u003eThe 2025 Srixon Z-Star Diamond is the most versatile and arguably the most impressive performer in the entire Z-Star family. Originally developed for Brooks Koepka and now trusted by a growing number of Srixon Tour staff, the Diamond sits between the softer Z-Star and the longer Z-Star XV, but in independent testing it consistently outperforms both. With a compression of 100, the Diamond's slightly firmer core and reduced compression profile minimises driver spin for exceptional carry distance off the tee, while generating remarkable spin on iron and wedge shots that rivals and often exceeds the rest of the range. In MyGolfSpy's 2025 ball test, the Z-Star Diamond took gold medals in tee-to-green performance, approach play and short game performance - generating over 6,100 rpm backspin on a 40-yard pitch shot, making it one of the highest-spinning Tour balls tested. It is genuinely one of the best-kept secrets in premium golf balls.\u003c\/p\u003e\n\n\u003cp\u003eThe FastLayer DG Core 2.0 starts soft at the centre and firms progressively outward, with the Diamond's unique formulation tuned to balance long-game distance with the precision iron and wedge spin that better players demand. Srixon's Spin Skin+ coating applies a friction-enhancing urethane layer over the new biomass cover, allowing grooves to bite more aggressively on approach shots and around the green. The 338 Speed Dimple Pattern delivers a flatter, more penetrating ball flight off the tee that holds its line in the wind, while the extra-thin biomass urethane cover provides a soft yet responsive feel that sits perfectly between the Z-Star and XV. For players who want the complete package - distance, iron control and elite greenside spin - the Z-Star Diamond in white is the one to play.
