Etymology
Quadratite is named after the Latin word 'quadratus,' meaning square, in reference to the square cross-section of its crystals.
How to recognize it
Quadratite can be identified by its metallic luster, dark gray to black color, and relatively low hardness of 2.5 to 3 on the Mohs scale. It can be distinguished from other similar sulfosalt minerals by its specific chemical composition and tetragonal crystal habit. A streak test may reveal a dark gray streak. Due to its rarity, it is often confused with other dark sulfide minerals, but its unique composition and crystal form help in accurate identification.
Trivia
Quadratite is notable for its unique tetragonal crystal structure, which gives it a square cross-section. It is one of the few minerals containing both silver and cadmium in its chemical formula, making it chemically unusual. Additionally, its name reflects a distinctive morphological feature, emphasizing the square shape of its crystals.
