Apatite from Morocco's Imilchil Mine is well-known, generally as small sharp crystals from 1-3 cm. This is a monster! The crystal is a huge, doubly-terminated barrel shape, of solid apatite! It is dramatic and so impressive in size and weight, that at first glance you see the geometry of this elongated six-sided prism and assume that you are looking at a heliodor beryl. It is colorful, although not particularly glassy or translucent. We bought this at a show ages ago and have not seen comparable.
