The area around Cerro Huanaquino is best known for its excellent Magnetite specimens, but a close second behind these pieces are the attractive and very well crystallized Carbonate-rich Hydroxylapatite crystals. Carbonate-rich Hydroxylapatite is actually a variety of Hydroxylapatite, and is well-known from a fair number of world localities, but not often are the crystals as large, attractive and well-formed as the Bolivian specimens. This piece is a great thumbnail sized specimen of Carbonate-rich Hydroxylapatite with well-defined hexagonal form, a soft peach-tan color, medium luster, and is somewhat translucent. It is one of the better crystals of this rare material that I have handled.
