    Beautiful MALACHITE specimen in botryoidal form. Rich, green color. This piece glistens in the light. Collected in the 1990’s from the Mashamba West Mine in the Democratic Republic of Congo. From the collection of Roger Maynard, Roger is a friend and was a long-time geologist with the US Geological Survey in New Mexico.

    MALACHITE is a copper carbonate mineral, frequently found with Azurite. It occurs as a secondary mineral in the oxidation zone of copper deposits. Malachite is a banded light and dark green crystal with a dull and silky luster. Its various crystal habits include massive forms that are botryoidal, stalactitic or globular. The crystals are fibrous and are frequently found as pseudomorphs of Azurite. Malachite is very popular mineral among collectors and lapidary and jewelry artists. It belongs to the Monoclinic Crystal System. Hardness is 3.5 – 4 on the Mohs’s scale.

    Metaphysical properties: Malachite is an important protection stone. It absorbs negative energies and pollutants. Malachite is an extremely versatile healing stone. Malachite lowers blood pressure and treats asthma, epilepsy, fractures, swollen joints, growths, travel sickness, vertigo, and tumors. It enhances the immune system. Malachite can assist in restoring strength and vitality after illness and in rebuilding or repairing tissue after surgery.

    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.

    LocationPomba pit, Serra das Éguas, Brumado, Bahia, Brazil

    Metaphysical propertiesUvite diminishes fears and promotes self-confidence, awakens one from illusions, brings an awareness of reality, and enhances fortitude.
