APATITE AND ORANGE CALCITE

This is a natural  stone of apatite with orange calcite.I bought this on my last trip to Brazil as one chunk of rough.I had it cut and treated with opticon as the apatite crystal is a differnt hardness to the calcite so it can under cut the stone.Top collectors item due to its rarity. Under strong lights the crystals in the Apapite light up making it a intersting stone.

Top polish on this stone.
Weight 16.22 cts
Size 20X16X6  mm

 

Apatite is a group of phosphate minerals, usually referring to hydroxylapatite, fluorapatite, and chlorapatite
Apatite is a common mineral, and fine localities are worldwide. Enormous deposits are in the Kola Peninsula, Russia, containing both crystals and botryoidal material. Some of the finest crystals came from Ehrenfriedersdorf, Saxony Germany, where they are blue to purple in color. Colorless, hexagonal crystals were found in the Tyrol, Austria, and excellent material from Panasqueira, Portugal. Deep blue crystals are found in Campo Formosa, Bahia, Brazil, and in Sri Lanka. Enormous deposits mined for industrial use exist in Nauru, Morocco, Algeria, Tunisia, Egypt, and Israel.
Perhaps the most famous specimens are the gemmy yellow crystals from Cerro del Mercado (near Ciudad Durango), Durango, Mexico. In Ontario, Canada, large greenish-brown crystals come from Wilberforce, Haliburton Co., and the Bancroft area. Also in Canada is Otter Lake, Quebec, where large crystals occur on a matrix of orange
Calcite.
In the U.S., famous violet crystals come from the Mount Apatite area (Hebron), Androscoggin Co., Maine. Prismatic green crystals closely resembling Tourmaline is found in Mesa Grande, San Diego Co., California.
