Chemical composition of Sphene
Sphene is a silicate of calcium and titanium, and owes its color to the presence of iron. Its color ranges from yellow-green to green and even brown hues. Due to its low hardness (5 – 5.5 on Mohs scale), it is a difficult gem to cut.
The principle Sphene deposit lies in Madagascar, but a few examples have also been extracted in Brazil, Canada, Mexico, Myanmar, Austria, Pakistan, Sri Lanka and the U.S. The raw material is extracted directly from the mother rock, also known as effusive rock.
The history of Sphene
This Titanium mineral was first discovered in 1795 in Hauzenberg, in the Bavarian forest. Sphene is a relatively new gemstone to the market, and thus has no myths or traditions associated with it.
