Talc ps. Quartz Talc ps. Quartz Talc ps. Quartz Talc ps. Quartz

Rare pseudomorph of Talc that has replaced a number of well formed Quartz crystals. There is a horizontal row of at least 7 crystals, with the tallest 1.7cm in height. Classic and now hard to find pseudomorph from what is, to my knowledge, the only worldwide locality that has produced these pseudomorphs. These were found over 100 years ago and have not been found since.
