Physical properties
Hardness: 6.0-6.5 (Mohs), Color: Pink to manganese-red, Luster: Vitreous to pearly, Crystal structure: Orthorhombic, Cleavage: One perfect direction, Specific gravity: 3.10-3.38
Formation & geological history
Forms in regional metamorphic environments where manganese-rich solutions interact with calcium-rich rocks. Often occurs in hydrothermal veins cutting through mafic rocks.
Uses & applications
Used primarily as an ornamental stone, for lapidary work (cabochons, carvings like the torso shown), and in jewelry or as a healing crystal in metaphysical communities.
Geological facts
Thulite was first discovered in Norway in 1820 and is named after the mythical island of Thule. It is the pink variety of the same mineral group as Tanzanite.
Field identification & locations
Identify by its distinctive pink color and lack of transparency. Common locations include Norway, Namibia, and Australia. Collectors should look for vibrant pink saturation.
