Genuine Tibetan crystals are relatively rare. Here's a selection of the real thing sourced on the northern slopes of the Himalayas. High vibration quartz.
"Tibetan quartz crystals have been used to promote contact with the ancient cultures of the East, bringing knowledge concerning healing and spirituality to the user. In addition, healing and meditation have both been enhanced. Kirlian photography has shown that, when cleansed, these crystals emanate the total spectrum of color, and can hence be applied to all energy meridians for stimulation and cleansing and can be used in the healing of all centers."
