This large chunk of Golden Mica with Tourmaline, 2-3 inches in diameter, is great for any mineral collection.

This new rare discovery from Brazil is a fusion of two of the most prized minerals: Black Tourmaline and Golden Mica. Stunningly beautiful.

Tourmaline’s name comes from the Sinhalese word “turmali,” which means “mixed.” Tourmaline, occurring in more colors and combinations of colors than any other gemstone variety, lives up to its name. Known for centuries, tourmaline first gained popularity when the Dutch began to import it in the early 17th century from Sri Lanka . Tourmaline is actually the name of a group of related mineral species. In gemological practice, individual species names are not used. Instead, all are simply termed tourmaline.

Golden Moscovite Mica is a common rock-forming silicate, ranking No. 4 on the Mohs scale of hardness. It has a variable chemical composition of potassium, magnesium, silicon, and oxygen, with water in its crytalline structure. Large, clear plates of mica where once commonly used for windows, but more often used as an insulator.
