Sphene is the gemstone name of the mineral Titanite. Sphene is known for its exceptional dispersion, resulting in gemstones that show brilliant fire. The dispersion of Sphene exceeds even that of Diamond. However, the relatively low hardness of Sphene inhibits its use as a mainstream gemstone.
About
Sphene comes in several colors, but the most prevalent color used in gemstones is yellowish-green to orange-brown. Sphene is also strongly pleochroic, with different colors at different angles. Sphene gemstones often have inclusions and flaws, especially when in larger sizes. Clean Sphene gemstones are uncommon and are highly sought after.
Uses
Sphene is a minor gemstone and used mainly for collectors. Since Sphene gemstones have a low hardness and are easily scratched, they are limited to earrings and pendants when used in jewelry.
Treatments & Enhancements
Although the color of Sphene gemstones may be turned red or orange through heat treatment, most Sphene gemstones remain untreated.

Gem Sphene sources include Austria, Brazil, Pakistan, Namibia, Madagascar, Russia, and Sri Lanka.
