Sphalerite luster

Sphalerite is very soft, 3.5 to 4 on the Mohs scale. That means it will lose its luster just from normal cleaning. It's also brittle and has perfect cleavage. There is no way this gem could stand up to the abuse a ring stone receives. However, sphalerite could be used in a pendant or brooch worn only on special occasions. Donald Clark, CSM IMG

Sphene the Gemstone. Sphene continues to be the name used for titanite in the gem and jewelry industries. It is a minor gemstone that is popular with collectors because of its high dispersion. Sphene is one of the few minerals with a dispersion higher than diamond. The dispersion of diamond is 0.044, while the dispersion of sphene is 0.051.Pretty composition, sphalerite has a beautiful metallic luster. 6,5 x 6 x 4 cm.Sphalerite.
