Dragon Minerals - October 30, 2020 Update

A large, single fluorite crystal, violet to (mostly) grey in color, and slightly frosty. (Fluorite color tends to be dependent on illumination. The photos seen here were taken under white LEDs, and so the color you see in your mineral cabinet may be a bit different.) Intergrown with a knob of brown to black iron hydroxides/oxides. In some places the fluorite is a thin layer - a millimeter or two in thickness over the dark matrix, whereas in other spots there is nothing but fluorite. Intense blue fluorescence under longwave UV; milder, purpler fluorescence under shortwave. Somewhat contacted on the back where removed from matrix, but no significant damage is seen. Not the prettiest example from this locality, but the size and fluorescence intensity are notable.
