Kweh

I was in the mood for something simple and fast, with less than 50 facets but good light return, that worked for shallow rough. You can even scale this shallower for corundums - set P2 to 40.29* and C3 to 13.91*. I like this in yellow sapphire, but works in materials from feldspar to rutile (RI = 1.52 - 2.62) with no changes. Suggested size = 4-8 mm
