What is cool about this Tsumeb dioptase is the association with cerussite, represented by a gemmy jewel of a crystal perched right on the edge of a shallow depression in the matrix; it is a complete "threeling." The dioptase is a druse of sparkly microcrystals that wrap around to the back of the specimen.
