Shiva Lingam stones are found in the Narmada River in Onkar Mandhata, one of the seven holy sites of India. They're only gathered on one day each year. Ideal for celebrating masculine energy in its' most positive form.
 
These stones  are made of cryptocrystalline quartz and legend has it that they formed when a meteorite fell to earth several million years ago. The natural movement of the river is believed to help create the egg or oval shape of the stones.  Hand polished to give them a smooth and gleaming surface. Lingam stones are said to have one of the highest frequency vibration rates of all the stones on earth.
