A superb single crystal of Thorite from the Kemp Prospect, Ontario, exhibiting exceptional form and integrity for this rare mineral species. The crystal shows deep red-brown coloration with well-defined prism faces and a lustrous, slightly translucent quality when held to the light. Its solidity and preservation distinguish it as a choice, cabinet-sized specimen from a locality where intact crystals are seldom found.

The Kemp Prospect is known for producing highly localized thorium mineralization within granitic pegmatite veins, and individual crystals of this quality are rarely recovered. Most material is granular or partial; thus, a complete crystal of this size and sharpness is a remarkable find.

An ideal addition for collectors seeking a representative of Ontario’s thorium minerals, this Thorite crystal combines locality rarity, excellent crystallography, and radiological significance—a specimen that bridges both scientific and aesthetic appeal.
