✺ Glows under UV

Longwave UV (~365 nm)Usually inert. Rare colourless crystals glow red under longwave
Shortwave UV (~254 nm)Bright blue to bluish white

California's state gem, from the San Benito River area.

Reactions vary by locality and specimen; many specimens of a fluorescent species do not glow. Shortwave UV can burn skin and damage eyes. Wear UV-blocking glasses, and never look into any UV lamp. Sources: Wikipedia: Benitoite. More UV-reactive stones →
