Charoite is translucent lavender to purple in color with a pearly luster. Charoite is strictly massive in nature, and fractures are conchoidal. It has an unusual swirling, fibrous appearance, sometimes chatoyant, and that, along with its intense color, can lead many to believe at first that it is synthetic or enhanced artificially.
Color: Purple, violet, dark purple: Crystal habit: 6 sided prism ending in 6 sided pyramid (typical) Twinning: Dauphine law, Brazil law, and Japan law: Cleavage: None: Fracture: Conchoidal: Mohs scale hardness: 7 (lower in impure varieties) Luster: Vitreous/glassy: Streak: White: Diaphaneity: Transparent to translucent: Specific gravity: 2.65 ...
The Infinity Gems (originally referred to as Soul Gems and later as Infinity Stones) are six fictional gems appearing in American comic books published by Marvel Comics, named after and embodying various aspects of existence. The gems can grant whoever wields them various powers in accordance to the aspect of existence they represent, and have ...
Lapis lazuli (UK: / ˌ l æ p ɪ s ˈ l æ z (j) ʊ l i, ˈ l æ ʒ ʊ-,-ˌ l i /; US: / ˈ l æ z (j) ə l i, ˈ l æ ʒ ə-,-ˌ l i /), or lapis for short, is a deep-blue metamorphic rock used as a semi-precious stone that has been prized since antiquity for its intense color.
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 of iron within the crystal.
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]
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]
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 ...
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 ...
Emerald is a gemstone and a variety of the mineral beryl (Be 3 Al 2 (SiO 3) 6) colored green by trace amounts of chromium or sometimes vanadium. [2] Beryl has a hardness of 7.5–8 on the Mohs scale. [2] Most emeralds have many inclusions, [3] so their toughness (resistance to breakage) is classified as generally poor.
