Pyroclastic Flow

While I personally prefer classic trillion-type outlines, every so often a piece of rough looks like a great triangle with the corners clipped off. That's where this interesting, modern design comes in! I prefer it in red pyrope- almandine garnet, but it works in materials from feldspar to rutile (RI = 1.52 - 2.62) with no changes. Suggested size = 5-8 mm
