RM1721   Twinned fluorite and quartz

Heights Quarry, Bere Alston, Westgate, Stanhope, Co. Durham, United Kingdom

An aesthetic fluorite specimen showing a violet tone turned to pink, crystals very clear, transparent and arranged on tiny quartz crystals. But what makes this piece special is the triple interpenetrating spinel twin that shows the largest group of crystals. Others crystals show double interpenetration of two individuals. Very fluorescent under LW-UV. A more than remarkable piece.

Size: 8.2 x 6.3 x 4.5 cm.
Main crystal: 18 x 12 mm.

Col. J.M. Manchion (Barcelona).
Fluorescent under long wave UV
