Charoite. 2O is a rare silicate mineral, first described in 1978. It is named after the Chara River, despite its being 70 km away from the discovery place; the name of the river translated from Evenki means “to melt, melt.”. [6] [3] When it was discovered, it was thought to be a fake, dyed purple to give it its striking appearance.

Ametrine, also known as trystine or by its trade name as bolivianite, is a naturally occurring variety of quartz. It is a mixture of amethyst and citrine with zones of purple and yellow or orange. Almost all commercially available ametrine is mined in Bolivia. The colour of the zones visible within ametrine are due to differing oxidation states ...
Rhodochrosite is a manganese carbonate mineral with chemical composition MnCO 3. In its pure form (rare), it is typically a rose-red colour, [5] but it can also be shades of pink to pale brown. It streaks white, [6] and its Mohs hardness varies between 3.5 and 4.5. Its specific gravity is between 3.45 and 3.6. [7]
Kyanite is an aluminum silicate mineral, with the chemical formula Al2SiO5. It is typically patchy blue in color, though it can range from pale to deep blue [6] and can also be gray or white or, infrequently, light green. [7] It typically forms sprays of bladed crystals, but is less commonly found as distinct euhedral (well-shaped) crystals ...
Grey (more common in Commonwealth English) or Gray (more common in American English) [2] is an intermediate color between black and white. It is a neutral or achromatic color, meaning literally that it is "without color", because it can be composed of black and white. [3]
Chrysoberyl. The mineral or gemstone chrysoberyl is an aluminate of beryllium with the formula Be Al 2 O 4. [5] [6] The name chrysoberyl is derived from the Greek words χρυσός chrysos and βήρυλλος beryllos, meaning "a gold-white spar". Despite the similarity of their names, chrysoberyl and beryl are two completely different ...
Magnetites, biotite, sphene, and quartz. Andesite ( / ˈændəzaɪt /) [1] is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica -poor basalt and silica-rich rhyolite. It is fine-grained ( aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus ...
