Thortveitite is a rare mineral consisting of scandium yttrium silicate (Sc,Y)2Si2O7. It is the most widespread scandium mineral,[1] but natural thortveitite is not widely exploited as a source of scandium metal. Most scandium is derived from mine tailings, which can include thortveitite.[2] Thortveitite mining in the United States ceased in 1969.[3]
Occurrence is in granitic pegmatites. It was named after Olaus Thortveit, a Norwegian engineer. It is grayish-green, black or gray in color.[4][5][6][7]
A transparent gem quality example was found in 2004, and reported in The Journal of Gemmology.[8]
