How many facets can YOU get to meet correctly in a single meetpoint? Well, this pattern has 3 sets of 8-facet meetpoints, and 3 sets of 10-facet meetpoints. Good luck - you'll need it. And no, I won't test-cut this; it's too hard. Works in materials from topaz to YAG (RI = 1.61 - 1.83) with no changes, but I prefer it in tourmaline. Suggested size = 8-10 mm
