|Below is a gallery of Pseudomorphs 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. To purchase mineral specimens, go to the
