For your consideration is this very nice cluster of large well-formed brown 

P a r i s i t e - (C e) crystals from the Snowbird mine, Fish Creek, Alberton, Mineral County, Montana USA. The Snowbird mine, which exploits an REE-rich carbonatite dike, is one of the classic worldwide localities for P a r i s i t e - (C e). Recently, I was able to obtain a group of exceptional specimens of this unusual REE species directly from the person that collected them. Most of these crystals at this locality are <2 cm., this is a superb large specimen of this species for this mine! Rare!

Specimen Dimensions: 4.4 x 4 x 3.5 cm. Weight: 98 grams
