The name sphene is derived from the Greek word for “wedge”, because of its typical wedge-shaped crystal habit. It is also frequently called titanite due to its titanium content. This is a rare example of sphene in rough, with its classic triangular, or wedge-shaped habit and its bright chartreuse-green color and associated calcite crystal, height 1 ½ in. Sphene can be faceted although it is considered a rarity on the gem market. Here this very pretty cushion-shaped stone of brilliant chartreuse green with dispersive spectral flashes illustrates why the fire in sphene is often considered to be greater than that of diamonds, weighing approximately 6.20 carats and measuring 12.5 x 8.5 x 5.5mm.
