Geometric Etude #3

by Arya Akhavan (October 2013)

Here's another pattern following the same theme of a regular n-gon with every vertex connected. Of course, with the odd symmetry, it's got very high light return, and it has a very continuous domed crown, which I like. Works in materials from feldspar to rutile (RI = 1.52 - 2.62) with no changes, but I prefer it in peridot. Suggested size = 9-15 mm
