One of the few larger pieces of the single pocket found: Tabular, interconnected, lustrous and translucent, seafoam green crystals of borcarite, to 1.3 cm in length, make up this cluster. But more than that, the specimen is festooned with probably a hundred sharp, lustrous grayish- white cahnite crystals to 2 mm in size. Both species are beautiful, and truly rare, here.
