Malachite pseudomorph after Azurite

A very striking specimen featuring fibrous deep-green Malachite pseudomorphs after bladed Azurite crystals on a white clay matrix. The original Azurite retained its crystal form but was molecularly altered to (or replaced by) Malachite, thus the pseudomorph. The Malachite presents a silky and chatoyant (an optical reflectance effect, as in “cat’s eye,” arising from the fibrous structure of a material . . . ) luster, and although it’s a little wordy, it’s exactly this unique luster along with the pseudomorph formation that makes this particular specimen of Malachite eye-catching and unique. Very aesthetic piece in excellent condition.  Location: Milpillas Mine, Municipio de Santa Cruz, Sonora, Mexico Size: 9 x 7 x 6 cm
