Fluorite & Galena - Blackdene Mine, Weardale
Fluorite & Galena -
Blackdene Mine, Weardale, County Durham, England
33 x 30 x 25mm galena crystals to 15mm across
Lustrous purple cubed Fluorite, some displaying interpenetrant twinning with complex Galena crystals, quite typical for this classic Weardale lead mine. An excellent example.
As with all the Fluorites from here, it fluoresces a bright bluish violet very strongly under Longwave Ultraviolet. It also will look slightly different under incandescent light and LED and natural daylight.
Collected in 1974.
