- Schorlomite, Thomsonite-Ca
- Small Cabinet, 6.2 x 4.4 x 4.0 cm
- Magnet Cove, Hot Spring Co., Arkansas, USA
Schorlomite is a rare garnet species and thomsonite is a relatively uncommon zeolite group mineral. The famous Magnet Cove deposit is the Type Locality for schorlomite. This old-time specimen is essentially solid intergrown, blackish-brown schorlomite crystals. The crystals are euhedral to subhedral and the large crystal on top is 4.5 cm. Some crystal faces are very sharp, highly lustrous and are very well-striated. Little pods of cream-colored, lustrous and translucent lathes of thomsonite are scattered about. This is old-time material, probably around 100 years old, as there is a cloth label glued to the bottom of the piece. Ex. Mullane Collection.
