Red Uvite crystals are far less common then green ones. Luster is vitreous. The crystal is 1.4 inch in length. The white crystals are Calcite rhombohedrons. From the Brumado area of Bahia, Brazil.
UVITE is a member of the Tourmaline group. It is a calcium, magnesium, aluminum, boro-silicate mineral. The crystal system is Trigonal. Hardness is 7 – 7.5 on the Mohs scale. Uvite occurs primarily in calcium- and boron-rich, metamorphic and skarn-type environments. In 2020, the International Mineralogical Association redefined Uvite as two separate minerals that are end-members of a solid-solution series: Uvite now refers to the hydroxyl-dominant end-member, while Fluor-uvite is the correct name for the fluorine-dominant end-member.
Location: Pomba pit, Serra das Éguas, Brumado, Bahia, Brazil
Metaphysical properties: Uvite diminishes fears and promotes self-confidence, awakens one from illusions, brings an awareness of reality, and enhances fortitude.
