Lorenzenite is a rare mineral that was first identified in 1897 in rock samples from Narsarsuk Greenland.
In 1947 it was discovered to be the same as the mineral Ramsayite (now a synonym of Lorenzenite), discovered in the 1920s in Kola Peninsula of Russia.
Ramsayite is the old Russian name for Lorezenite.
Lorenzenite has a rather high luster which is due to the titanium content.
