Harlequin Square cut by Tony Carson

Addition # 3 – This design might look a little confusing to cut at first, but it is really pretty simple. It has a nice random large flash, I like to cut it in Ametrine to help enforce that look, any material works, 1-12cts. Cut in refractive indexes 1.54 to 1.76 (76%) with no changes.


Random – Cosine – ISO
