Pseudomorph Mineral Specimens For Sale
Pseudomorphs = False Form

Below is a gallery of  Pseudomorph mineral specimens for sale from John Betts - Fine Minerals in New York City, NY. Pseudomorphs are mineral specimens where a mineral has taken the form of a previously deposited mineral. Sounds simple, but the processes are diverse and elaborate. Some are created when a second mineral grows over another, then the original dissolves away. Some are replaced molecule by molecule, or atom by atom, until the second mineral has the exact shape of the original mineral. Sometimes a mold is made of the first mineral by a second mineral growing over it, then the original dissolves, then a third mineral fills the void, and finally the second mineral dissolves. Suffice it to say you could collect just pseudomorphs and have an endless variety of specimens. Common pseudomorphs include: Copper pseudomorph after Azurite, Descloizite pseudomorph after Cerussite, Malachite pseudomorph after Azurite, Malachite pseudomorph after Cuprite, Prehnite pseudomorph after Laumontite, Pyrolusite pseudomorph after Manganite, Stibiconite pseudomorph after Stibnite, Strontianite pseudomorph after Celetite.
