Fluoro-Richterite

This specimen features a single, twinned crystal of fluoro-richterite with a smaller attached "side-car" crystal. Despite minor bruising on the back, the crystal maintains a well-defined form and a satin-to-glassy lustre. Crystals of this quality are exceedingly rare and are primarily found in the calcite vein-dyke systems around the Tory Hill locality in Ontario. According to Mindat.org the locality was discovered around 1995 by local collector Steve Smith, this area, approximately 100 meters north of Gibsons Road, has yielded many notable Grenville specimens, including fluorapatite, titanite, and, of course, fluoro-richterite.

These crystals, which occur within or weather out of calcite vein-dykes, are prized by collectors worldwide for their rarity, impressive size, and clarity—qualities not commonly seen in this mineral.
