Description

Beautiful group of glassy, highly lustrous datolite crystals over dark grey sulfide mineralization. Some of the datolite crystals are fairly transparent, and so those parts of the specimen where the datolite growth over the sulfides is thinner have a dark grey appearance. This datolite is unusually sharp and the arrangement of a good portion of the crystals in parallel growth makes for a cool aesthetic. The largest crystal measures 2.7 cm. The top crystals are completely crystallized around the back, but they grew as almost a thin veneer on the matrix, and are not fully developed at the back. Most of the specimens I’ve seen from this latest find are damaged, while this one is almost perfect – minor chipping at the upper edge, but not distracting at all. There is a micro (ca 1 mm) pink axinite in association. Super datolite specimen!
