Euclase - Gem crystals with blue zoning
stock #18.1- 745
Alto de Giz Pegmatite, Equador, Borborema mineral province
Rio Grande do Norte,
2.4 x 1.8 x 1.5 CM (thumbnail)
Gemmy sharp and lustrous cluster of transparent, colorless Euclase crystals showing the deep indigo blue zone inside. An older specimen from finds years ago at Alto Do Giz. The crystals are doubly terminated, textbook sharp and nicely striated. In very good condition though some cleaving is noted on the backside but this presents very well and shows no damage on display. A nice clear Brazilian Euclase with the most desirable color inclusion.
Euclase- colorless gem crystal

Pre Holiday 2017
A perfectly clear, well terminated and sharp Euclase crystal. The faces show fine striations and the top shows a dual tip termination that is unique in our experience. If this was a blue Euclase with this clarity and sizeit would be valued in the 5 figures, but as it is colorless that is clearly not the case! An excellent example that is larger than most from this area of Brazil.
