Also known as Lemurian Seed Crystal, Lemurian quartz is a type of laser quartz crystal mined in the Diamantina region of Brazil. Crystals often display a characteristic pink caste due to a coating of oxidised hematite or similar iron-containing mineral. Lemurian quartz is believed to hold the wisdom of ancient Lemuria, a civilisation pre-dating Atlantis (information originally channelled by Madame Blavatsky of the Theosophy Society in the late 18th century), which, like Atlantis, is said to have sunk beneath the waves as a punishment for misuse of power. Like other quartz from the Diamontina Complex, it is exceptionally clear (beneath the coating and striation), and has a warm, friendly energy. Lemurian quartz makes an excellent control crystal.
