Characteristics of Pyromorphite

The color of the mineral is usually some bright shade of green, yellow or brown, and the luster is resinous. The hardness is 3.5 to 4, and the specific gravity 6.5 - 7.1. Owing to isomorphous replacement of the phosphorus by arsenic there may be a gradual passage from pyromorphite to mimetite. Varieties containing calcium isomorphously replacing lead are lower in density (specific gravity 5.9 - 6.5) and usually lighter in color; they bear the names polysphaerite (because of the globular form), miesite from Mies in Bohemia, nussierite from Nuizière, Chénelette, near Beaujeu, Rhône, France, and cherokine from Cherokee County in Georgia.

Trolleite Quartz
Trolleite Quartz is a rare variety of quartz known for its unique blue-green coloration, caused by inclusions of the mineral Trolleite. It is named after the Swedish chemist and mineralogist Hans Gabriel Trolle-Wachtmeister, who discovered it in the 19th century. Initially, trolleite Quartz was thought to be exclusive to Sweden's Vastana mine, making it an exceptionally rare gemstone. However, further exploration led to the discovery of additional sources, expanding its availability to some extent. Presently, one of the prominent locations for trolleite Quartz mining is the Minas Gerais region in Brazil.

Lazulite
Lazulite is a deep blue mineral that is often confused for the more famous (and also very blue) lapis lazuli. This rare stone, unlike the more amorphous lapis lazuli, has cleavage planes (essentially, angular faces along which the crystal may split). Lazulite is occasionally used to make jewelry – although only somewhat translucent in its native form, it can become relatively transparent when correctly cut.
