Malayaite
Ash Mountain, Tuya Range, Atlin Mining Division, British Columbia, Canada
Little vug filled with malayaite crystals. Fluorescent bright green under shortwave UV light, and an interesting dark orange under longwave, better with a 405nm blue laser. The green shortwave fluorescence seems typical in malayaite, the orange longwave not so much.
Shortwave fluorescence.
