Item Description

Safflorite is an uncommon cobalt iron arsenide. Spongy, moderately sparkly, safflorite microcrystals richly cover a thick vein of silver that is highlighted by a spinel-twinned, herringbone silver crystal cluster and has a bit of glassy calcite poking out. This is a THICK silver vein, up to 2.8 cm, on the sculptural wedge of greenstone matrix! The Castle Mine deposit was discovered in 1917 and operated intermittently until the late 1980s. Probably older material. VERY RICH and showy silver ore. 198 grams.
