Titanite is a mineral, a silicate of calcium and titanium.
The name sphene derives from the Greek "sphenos" which means pointed, referred to as the shape of the rough crystals
Hardness is relatively low in titanite (5 to 5.5 on the Mohs scale).
However, it also possesses gemological properties that make it a desirable piece for collectors and jewelry enthusiasts.
Sphene are often yellow, orange, brown and green hues, with many gradations between them, and often show a zoning of color.
The Kola Peninsula (Russia) appears to be the main source of this gem.
The scatter or fire of sphene is among the highest in the gem world. However, the color of the body, the degree of inclusions, the orientation of the cut and the style of the cut can enhance or obscure this characteristic.
The high birefringence of sphene usually results in a visible doubling of the facets within the stone.
Very rare in clean stones over 5-10 carats, even a flawless 5 carat sphene would be a rare stone.
When placed in protective environments and worn with care, sphenes can be a spectacular addition to your jewelry collection.
Titanite is a mineral from which it is possible to obtain titanium, an essential element for the preparation of metal alloys, to which it gives a high resistance to acids and corrosion.
