ID: CC17872
Colourless Euclase crystals, each containing a pale indigo blue phantom within the apex of the termination, sit on a part-glassy and heavily etched Quartz crystal. Euclase is a beryllium aluminium hydroxide silicate which is found in pegmatite deposits where it can be of gem quality.  The largest Euclase crystal measures 1.9 cm overall.  An interesting specimen from the Alto do Giz pegmatite in the Borborema mineral province of Rio Grande do Norte, Brazil.
