While playing some Donkey Kong Country and listening to "Life in the Mines", I decided I wanted an Old Mine-style barion, but couldn't remember what the standard crown was. So, I wrote this instead. Works in materials from orthoclase to rutile (RI = 1.52 - 2.62) with no changes, but I prefer it in pink-flash amethyst. Suggested size = 9-12 mm
