Copper compounds
Many minerals have beautiful colours, but for the greatest range of colours of opaque stones, you can't beat the copper compounds. Copper has always been a very important metal, and the compounds have been used for decoration, and to make pigments for paints, and cosmetics.
The specimen on the right is azurite (blue) and malachite (green). You often find both these minerals on one specimen.
