Sphene Gemstone Information
About Sphene - History and Introduction
Sphene is a very rare brilliant yellowish-green, green, orange or brown gemstone with a high lustre, also known as "titanite" due to its titanium content. The name "sphene" comes from the Greek word, "sphen", meaning "wedge", which alludes to the formation of its crystals. Due to its strong dispersion, when brilliant-cut, sphene can exhibit a fire similar to that of diamond.
Sphene has been known since 1787 and was named according to its titanium content in 1795 by Martin Klaproth. In 1801, it was given the name "sphene" by French mineralogist, Rene Just Hauy. In 1982, the International Mineralogical Association Commission on New Minerals and Mineral Names (CNMMN) decided to use the name "titanite" rather than "sphene". However, both "sphene" and "titanite" continue to be recognized in mineralogy circles, and sphene is the most frequently used gemmology term.

Identifying Sphene
Sphene can be identified by its high lustre, a refractive index that is typically over the limit of standard refractometers and intense fire, caused by a high dispersion. Sphene has a similar refractive index to
zircon
, but can be distinguished from zircon by its Mohs hardness score of 5 to 5.5, whereas zircon has a Mohs hardness of 6.5 to 7.5.
Sphene; Origin and Gemstone Sources
Sphene deposits are found in Brazil, Burma (Myanmar), India, Kenya, Madagascar, Mexico, Austria, Sri Lanka (Ceylon) and the USA.
Buying Sphene and Determining Sphene Gemstone Value
Sphene Colour
Sphene can occur yellow, brown, green or reddish and various shades in between, such as cognac colour. Intense green sphene is also known as "chrome sphene", due to the colour agent being chromium. "Chrome sphene" and yellowish-green sphene are the most desirable colours. Reddish sphene gets its colour from manganese impurities and is sometimes referred to as "greenovite".
Sphene Clarity and Lustre
Sphene is rarely free from inclusions and eye clean stones are rare. Gemstones in sizes over 5 carats are also rare and are highly valued. Sphene has an adamantine lustre, which combined with its high dispersion, makes it an attractive gemstone.
Sphene Cut and Shape
Sphene is cut in a variety of faceted shapes that show off its high dispersion and adamantine lustre. Sphene can be seen in shapes such as octagons, trillions, squares, rounds and fancier shapes, such as ovals, pears and cushions. Translucent to opaque stones are often cut en cabochon. Sphene can present a challenge to lapidarists, due to its brittle tenacity and softness, but is worth the effort, since when faceted and polished it yields stunning results.
Sphene Treatment
Sphene is not generally treated or enhanced, though the colour can be changed to red or orange by heating. However, most sphene gemstones are untreated and naturally orange and reddish sphene is available.
