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.
