From a very important find made almost a decade ago, a fine pseudomorph or epimorph of blue-green Chrysocolla in the shape of free standing Azurites. The Azurites were long ago altered to Malachite and most of the Malachite has been dissolved away though a few remnants remain. Nearly all of these forms are now fully hollow, forming a cast after the former crystals. There have been other finds of Chrysocolla after Barite and other minerals from this area but the Azurite forms are perhaps the most impressive. In very fine condition, unlike most of the find, on this piece the crystals are intact, complete and up to 2.5 CM free standing.

A fine example of this remarkable pseudomorph. On this piece the original crystals of Azurite were replaced by Malachite which is a fairly common alteration, it preserves perfectly the shape of the Azurite crystals. The Malachite is then replaced by or overgrown with Chrysocolla which replaces the green Malachite with a bright blue color. On this specimen a little of the green Malachite can still be seen in the center of some smaller blades, but overall the entire piece is a bright blue. In fine condition overall, all of the large blades on the display side are intact and undamaged, only the backside has a few small broken blades that are not visible on display. This was from a 2015 find that had an especially great form, later materials did not look like this. An excellent and esthetic Copper secondary specimen with fine color. The largest of the original crystals is about 3 CM which was huge in this find.

An eye-catching complex cluster of very sharp crystal forms that show clearly the original shape of the Azurite crystals that were altered to Malachite and are now nearly all Chrysocolla. A few of the smaller crystals have broken section that show the core of unaltered Malachite. Other crystals are now hollow as well, reaching up to 3.2 CM long. Overall this is a delicate specimen that is very 3 dimensional and a choice cast form . One of the mineralogical discoveries that made big news about 2 years ago, these are now quite scarce on the market.

Really fine form and rich color on this specimen from the recent finds at Luputo. The pseudomorph retains the shape of the original Azurite crystals that were rep[laced by Malachite and finally replaced by the blue Chrysocolla. The delicate array of crystals is on a Gossan matrix and in excellent condition despite the fragility. The discovery of this material made big news in the mineral world. This is a choice example with particularly distinct crystal shapes well presented.

One of the most exciting new finds this year are these very colorful pseudomorphs from the Congo. This specimen is especially well-formed with big (up to 6.2 cm) sharp crystals showing Azurite form. The crystals are now hollow casts with a small amount of residual Malachite seen inside with magnification. The entire specimen is covered with tiny, sharply terminated crystals of deep blue Chrysocolla. In fine condition esthetic and eye-catching.
