TOURMALINE, variety UVITE. The crystal has dark brown color with a hint of red on one of the edges. 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.

This piece glitters! Stunning color contrast of green Siderite “Blades” with brassy iridescent Chalcopyrite, whitish Calcite, and gray Tetrahedrite crystals in this specimen. The green blades of Siderite in this piece are very rare! Several of the Siderite blades are at least 0.5 inch long. The Calcite crystals are flattened and translucent. The luster of the Siderite is vitreous while the Chalcopyrite and Tetrahedrite have a brilliant metallic luster.
