Malachite infused quartz separates a botryoid of drusy, rich green malachite on one side from the sharp, lustrous, dark green crystals of clinoatacamite on the other half of the specimen...A neat duality! The clino's reach to 1 cm in length. In addition, there are two translucent, gray calcite crystals perched near the atacamite, that reach 6 mm.
