Euclase is a rare and precious mineral, valued for its beauty and unique properties. In lithotherapy, it is recognized for promoting mental clarity and personal expression.
1. What is the technical and scientific profile of Euclase?
Euclase is a beryllium and aluminum silicate with the chemical formula BeAlSiO4(OH). It crystallizes in the monoclinic system, forming often striated prismatic crystals. Its hardness is 7.5 on the Mohs scale, and its density ranges between 2.99 and 3.1. It has perfect cleavage along the {010} plane, which makes it fragile despite its hardness. Its color varies from pale blue to dark blue, but it can also be colorless, white, or light green. Its luster is vitreous, and it is transparent to translucent.
2. Where are the Euclase deposits?
The main Euclase deposits are found in Brazil, notably in Ouro Preto in the state of Minas Gerais, where it is associated with topaz. It is also found in Colombia, Russia (in the Orenburg district, in the Southern Urals), Austria (in the micaceous schists of Rauris, in the Austrian Alps), as well as in Zimbabwe and Tanzania. These deposits produce crystals of varying quality, some being particularly prized for jewelry.
3. What is the rarity level of Euclase?
