From the Narmada River in India,come these unique and powerful stones. Physically they are made up of Cryptocrystalline Quartz, which is a natural composite of Quartz, Jasper,Agate,Chalcedony, and Iron. They are naturally egg shaped, and hand polished to bring out their luster. They only come from this one spot in the Narmada river, which is a tributary to the Ganges. They are called “Shiva” Linghams, also spelled “Lingam”and are in temples throughout India. They are held as embodiments of Shiva. They represent the masculine and Feminine in balance. No two are alike, with an infinite verity of shades,colors and energies. The “Black” Linghams we offer are extremely rare, they are naturally “Jet” black,and are very powerful healing stones.
