Shiva lingam is
a powerful respresentation of Lord Shiva in Hindu culture. This Lingam is
considered to be the third eye of Lord Shiva and hence, taken to be very
powerful stuff. Some of the gemstone lingams we have are Ruby Zeocite Shiva
lingam, Crystal Quartz, Pyrite Shiva lingam, Dantric Agate Shiva Lingam, etc.
