English: Calcite (Var.: Cobaltoan Calcite)
Locality: Bou Azzer, Bou Azzer District, Tazenakht, Ouarzazate Province, Souss-Massa-Draâ Region, Morocco (Locality at mindat.org)
Size: 12 x 5.7 x 4.5 cm.
A beautiful new find: light pink cobaltoan calcite from Bou Azzer. Unlike most material from this locality, this piece features sharp scalenohedra sticking up from the matrix like a porcupine’s quills. There are very few broken crystals, and all are very translucent or almost gemmy. There is a white secondary growth preferentially deposited on some faces which makes for a nice accent rimming the base of some crystals, highlighting their individuality. One of the neat features of this piece is the fluorescence - while the entire piece glows red/orange under SW UV light, the tips of the scalenohedra glow much brighter and more orange.
