Description

This is a wonderful, well sized prasem quartz with magnetite pseudomorphs after hematite roses on contrasting whitish hedenbergite matrix. The crystal size is great and the aesthetics are also excellent. The piece is in excellent condition. The main crystal was stabilized as it was loose. A magnificent combo example of the classic Seriphos prasem. From my personal collection.
