What is titanite?

Titanite is frequently called by the name Sphene, which was the more popular term for this mineral prior to 1982. In 1982, the IMA adopted the official name as Titanite and discredited Sphene. The name Sphene is still frequently used, especially in Europe. Sphene also persists as the more prevalent name for faceted Titanite gemstones or transparent crystal forms.

Formula

CaTi(SiO 4)O
