Malachite with Crysocolla and Druzy Quartz

This is an interesting specimen of Malachite and Crysocolla surrounded with Druzy Quartz. 'Druzy' is what we call the finer crystalline forms of minerals, compared to larger crystal structures (like those on a typical piece of Amethyst), which gives a glittering look to the piece. The Malachite has brighter and dark green sections, with bits of Crysocolla blue peeking out here and there.
