Mineral Notes:  Malachite is a well known and popular semi-precious stone and is named after the Greek word for "mallow", a green herb. The banded light and dark green designs give it a unique ornamental quality unlike that of any other stone. The bands and colour are so distinctive that malachite is one of the most easily recognised minerals by the general public.
