Item Description

A wonderful old time classic Fluorite from Weardale showing excellent interpenetrant twinning (on a cube-diagonal twinning axis). The color is a soft purple hue that has a bit more of a rose-pink tone when backlit. The crystal is over 2 inches, which is very good sized for a Weardale Fluorite. There is a little bit of roughness, so the piece is not 100% pristine, but it's still a very worthwhile example of this beloved material from northern England. Valued at $650. From the worldwide collection of David Burgess (1951-2016). David was a prolific species collector from Newington, Connecticut, and the namesake for the extremely rare cobalt arsenate species Burgessite, which he discovered.
