Rock Crystal with Rutile
Rock Crystal belongs to the Quartz group. The mineral has a hardness of 7 on the Mohs scale, and can be easily processed and set. It is the colorless variant of the Quartz family, and impresses due to its clarity. The most unusual about the Rock Crystal are its natural inclusions, which give each stone its individual character. The various minerals including Goethite, Pyrite, Rutile, Tourmaline, Calcite, Cacoxenite are seemingly floating inside the crystal. This diversity is the Rock Crystals most charming quirk, which makes it so distinctive and desirable.
