Tugtupite

Tugtupite was first discovered in 1960 in Greenland, where it is carved for jewelry. Colors include dark red to bright pink, and shades of orange. It may look mottled. When it is placed in the dark, the paler parts of the rock fade to white, but exposure to light restores the color. It is common to find white albite feldspar in the host tugtupite rock.

Tugtupite derives its name from its occurrence in Tugtup, Greenland. It means reindeer stone.

Occurrence

Tugtupite is found as massive opaque material in pegmatite veins. It also occurs in northern Russia.
