A fine 2 x 1 cm crystal of primary Malachite nestled in a Dioptase/Quartz pocket along with a beautiful 1 cm Dioptase and several gemmy Quartz crystals. The luster on all the crystals is excellent. Primary malachite, that has formed on its own chemical bonds and not without subverting and replacing a previous fine azurite crystal, is rare in this magnitude. This is a very robust primary malachite crystal with unusually developed termination. Ex. Charlie Key Collection.
