Lingams are only found at the Narmada River high in the mountains of Mandhata. One of the Seven Sacred Holy Places of Pilgrimage in India. Each lingam contains sacred markings symbolic of the marks of Lord Shiva’s forehead. The stones are “Crypto Crystalline Quartz”, said to contain the loftiest vibration of all stones on Earth. They emanate a vibration that will purify your temple or home. The stone represents both the male energy of knowledge and the female energy of wisdom. No two stones are alike. The stones have been tumbled.
