A choice set of 3 matched crystals of superb quality, all with absolutely pristine and even, similarly colored malachite alteration over the original cuprite. These are examples of one of the French classics of the early to mid 1800s. Today, they still turn up on the market often enough to see, but not in such size and pristine condition, very often. And the modified, complex habits are harder to get than the simple octohedra. In this set: the upper right crystal is 2 cm across, to 1.2 cm on edges; lower right is 1.4 cm on edge of the octohedron, and the left crystal is 1.3 cm on edges. All are pristine floaters, 360 degrees. From a museum collection, and also previously from the Schortmann collection. Based on prices I saw at Munich, I think these could sell for more if separated (a shame). I had 3200 euros on it at the show, when I had just exchanged for them from a collection. at $4000 USD now, thats even a bit less.
