Polycrystalline growth of an Azurite crystal completely pseudomorphed by Malachite with satin luster and very deep and uniform color. The crystal sits extraordinarily well implanted on the matrix in which there are also more Malachite pseudomorphs after Azurite crystals. The specimen is from the Philippe Morelon collection (No. 144), whose label we will send to the buyer.

TF48AL1: Malachite after Azurite

Very 3-dimensional growth of Malachite pseudomorphing equidimensional crystals of Azurite, with very well defined faces and edges, intense color, on matrix. Before the Azurite started altering to Malachite a thin dark coating, probably Cuprite, formed on the faces of the crystals, as suggested by the mineralogy of the locality and some of the crystalline forms, apparently octahedral, present in the matrix.
This great quality piece comes from the collection of Rock H. Currier (No. 4667) whose label we will send to the buyer.
