Thulite (sometimes called rosaline) is a translucent, crystalline or massive pink manganese-bearing variety of the mineral zoisite.

[1] Thulite is often mottled with white calcite and occurs as veins and fracture fillings transecting many types of rock.

[2] Thulite was first discovered at a place called Sauland in Telemark county, Norway in 1820.

[3] Thulite is used as a gemstone and carving material in the manufacture of jewelry and ornamental objects.

The occurrence is spread throughout the Namib Desert and generally has ridges with a NE to SW setting.
