Wagnerite

Papagoite is a rare cyclosilicate mineral. Chemically, it is a calcium copper aluminium silicate hydroxide, found as a secondary mineral on slip surfaces and in altered granodiorite veins, either in massive form or as microscopic crystals that may form spherical aggregates. Its chemical formula is CaCuAlSi2O6(OH)3. It was discovered in 1960 in Ajo, Arizona, US, and was named after the Hia C-ed O'odham people (also known as the Sand Papago) who inhabit the area. This location is the only papagoite source within the United States, while worldwide it is also found in South Africa and Namibia. It is associated with aurichalcite, shattuckite, ajoite and baryte in Arizona, and with quartz, native copper and ajoite in South Africa. Its bright blue color is the mineral's most notable characteristic. It is used as a gemstone.

Fake Malachite refers to imitation or synthetic materials that resemble the appearance of genuine malachite, a green mineral known for its distinct patterns and colors. Fake Malachite can be made from various materials such as glass, resin, plastic, or dyed minerals. It is often used in jewelry and decor as a more affordable alternative to real malachite. However, it lacks the same properties and value as the genuine stone.

Anorthite is the calcium endmember of the plagioclase feldspar mineral series. The chemical formula of pure anorthite is CaAl2Si2O8. Anorthite is found in mafic igneous rocks. Anorthite is rare on the Earth but abundant on the Moon.
