Srixon Z-Star Diamond Golf Ball Review

50 Words or Less

The Srixon Z-Star Diamond golf ball offers substantially different long game performance than its brothers.  Firm feel akin to the Z-Star XV.


Srixon’s premium golf ball started 2021 with a bang, winning the year’s first major.  They’re starting this year with a different kind of excitement: the announcement of a third Z-Star golf ball.  In this review, I’ll break down what Z-Star Diamond brings to the game.

Check out our review of the Z-Star and Z-Star XV HERE


Srixon rates the Z-Star Diamond as “Soft” which is the same as the Z-Star XV.  The standard Z-Star is rated as “Softer.”

On the greens, I found the Z-Star Diamond nearly indistinguishable from the Z-Star XV.  Both are noticeably firmer than the Z-Star.  For those that really want to pick the smallest nits, the sound of the Diamond off the putter is fractionally lower pitched than the XV.

From the wedges through the driver, I found it impossible to feel or hear a difference between the Z-Star Diamond and the Z-Star XV.  The standard model can be picked out as being a bit softer if you’re paying close attention.

Short Game

In the short game, Srixon rates the Z-Star Diamond as having spin between the Z-Star and XV.  They state that the Z-Star has “Highest” greenside spin with the Z-Star XV being simply “High.”

In my testing, I found very modest differences between the three models.  On long pitches and near-full wedges, the difference was not more than a couple hundred RPM.  Though the margins were small, I did see the same order as Srixon, with the Z-Star spinning the most.

This tight grouping in short game spin is probably a positive for most players as it allows you to get your preferred long game performance without sacrificing short game control.  For the few players who want less wedge spin, the Z-Star family may not be for you.

Long Game

In the long game, the three Srixon Z-Star golf balls separate themselves more clearly.  During iron testing, the Z-Star Diamond produced about 10% more spin the other two.  I did not see a meaningful difference between the Z-Star and Z-Star XV.

That same gap was present in testing with the driver.  Srixon states that the driver spin from the Z-Star and Z-Star XV is “Low,” and my experience is that they are two of the lower-spinning Tour balls.  The Z-Star Diamond is noticeably higher spin off the tee.  This will make it a good choice for low spin players and those who want to shape their drives.  It might also work well for those who strongly favor carry distance over roll.


Srixon staffer Brooks Koepka has found his new gamer with the Srixon Z-Star Diamond.  If you’re seeking elevated spin off the tee and in your approach shots, this might be a great choice for you as well.

  1. Guys with a swing speed of 85 to 90 would the Srixon diamond ball be of any or more benefit to me

      That probably won’t be the best fit for your long game, but you’ll still get the short game performance out of it. My advice is always to buy a sleeve and see if you like them, or get a professional fitting.


  2. Recently played a sleeve and found these balls to be great for my game. Great off the tee and with approach shots. Hits the window that I aim for (no pun intended). Great spin on the green with the check that I want. Off the putter, it’s firm but true. Played the Z Star and Z Star XV, but truly think the Z Star Diamond is the “Goldilocks” ball for me.

    In robot testing at 85mph was 1yrd behind the longest ball and also no.2 for spin with 7iron. 4th with wedge spin from 35yrds. Best ball overall in these categories.
