Quartz pseudomorph after Fluorite

ID: CC17202
Wheal Mary Ann at Menheniot in Cornwall is most famous for its fluorite and, as in this great specimen, pseudomorphs of Quartz after octahedral Fluorite.  Typically, these pseudomorphs are between 5 and 10 mm on edge, but this fabulous example is a massive 2.5 cm along each of its edges!  The pseudomorph forms a four-sided pyramid, the upper half of an octahedral Fluorite crystal and sits on a creamy-white bed of gently undulating drusy Quartz.  This specimen was collected by the late Maurice Grigg in 1987 from the then, productive mine dumps.
