Sphene, or titanite, is a rare brilliant yellowish-green to green gem noted for its strong trichroism (3 colors visible in the stone) and its extremely high dispersion or “fire”, which is higher than diamond. The name sphene is from the Greek word sphenos, which means wedge, due to the shape of sphene crystals. Sphene is rarely free from eye visible inclusions but the intense fire and its vibrant color more than make up for this. Remarkable and quite distinctive in appearance, this gem is found in Brazil, Myanmar (Burma), India, Kenya, Madagascar, Sri Lanka and the US. Most desirable is yellowish green to green but sphene is also available in orange or brown.
