prasine

From Middle English [Term?], from a combination of Middle French prame (inherited from Late Latin prasinus) and Middle French prasine (borrowed from Late Latin prasinum), both ultimately from Latin prasinus (“leek-green”), from Ancient Greek πράσινος (prásinos), from πράσον (práson, “leek”).

It is possible that just as chrysocolla is silicated malachite, so prasine is phosphated malachite; the physical appearance of these minerals strongly confirms this view.
