Praseme

Info: Good developed crystals of this quartzite are rare. Praseme is most commonly found in microcrystalical masses. The green colour of praseme is because of the contamination of the quartz with amfibol and chlorite.

Found: The most important deposits of praseme were found on the islands of Aegean sea.
