About Serpentine

Serpentine is a broad group of magnesium silicate minerals with a waxy to greasy luster and colors ranging from mottled yellow-green and olive to dark blackish-green, and has been carved into decorative objects, jewelry, and architectural elements across many cultures for millennia. Antigorite and lizardite are the most common gem varieties, while the chatoyant green bowenite is one of the more prized forms. China, Afghanistan, New Zealand (where it is called tangiwai by Māori), and Peru are important sources.
