Shattuckite is a rare secondary copper silicate found in the oxidation zone of copper deposits. It was actually first discovered at Bisbee, but is best-known today in specimens from Africa. This is a dramatic, really rich and large specimen for this material, which has been trickling out from Namibia over the last 2 years. Numerous vugs, especially the striking large one, are lined with a thin crust of pretty blue, botryoidal shattuckite. Deposited on top of the shattuckite crusts are tiny drusy quartz crystals, which are included with minute amounts of shattuckite. This gives the gemmy sparkling quartz a rich deep blue color best described as a sapphire-blue. Add a few primary malachite sprays as an accent, and you have a very beautiful and interesting large cabinet combination specimen. Weighs 6.2 pounds or 2.8 kilograms.
