Euclase -blue crystals with Quartz
Lost Hope Mine, Mwami, Karol District
5.2 x 3.7 x 2.7 CM (small cabinet/large miniature)
A sizable cluster of Euclase crystals and sections of crystals on a nearly pure Euclase matrix. The color ranges from a light blue to a deep inky blue and the scattered Quartz crystals add a contrast. From the Lost Hope mine of Zimbabwe, this was found more than 40 years ago. The largest crystal is 2.6 CM in size but it must be noted it is closely encased in the matrix with only a few faces showing, and the better display angles do not present the best color zones. This is a sizable mass of Euclase with some gemmy areas and some nice striations on the larger faces, although the edges do have lots of cleavages and rough zones. Relatively affordable, the photos to me look a little bit better than the specimen in person but they are real with no photoshop tricks. A good value for this often very costly gem mineral.

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

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.
