Natural or dyed?
Black tourmaline is schorl, a tourmaline colored by the iron in it, so the black runs all the way through. It is almost never treated. We disclose all treatments on the product page.
Shiny or dull?
Raw crystals range from bright to dull, often with bits of white quartz, feldspar or mica from the rock they grew in. Most of our raw pieces get a light hand finish of jojoba oil, never mineral oil.
How do I know it's real?
On raw pieces, look for grooves running the length of the crystal and a rounded, three-sided cross section. Obsidian and man-made glass have no crystal shape, so they lack those grooves.
Care
At 7 to 7.5 on the Mohs scale it resists scratches, but it's brittle and can crack from a hard knock or a sudden change in temperature. Wash in warm, soapy water, skip ultrasonic cleaners, and dry it after.
