Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada A remarkable specimen of unusually large Genthelvite crystals to over 1 cm, with rich translucent grass-green color! Unusually attractive display-quality example of this often-earthy and ugly mineral species, PLUS it is of significant size and quality - what better combo is there?! 2 x 1.3 x 1.2 cm |
