rare crystal cluster of brilliant white dogtooth Calcites from New Mexico!
There are no photos of Calcite for this locality in mindat.org and this is the first
specimen I've seen
or offered on the website. The area around Silver City is known more for Copper and
but this is a very impressive Calcite plate featuring highly lustrous crystals of varying
sizes. The crystals
display somewhat jagged tips, much like the dogtooth Calcites one sees from Mexico. In

RARE!! Rhodochrosite crystals on Manganite matrix from Croatia!
This is a specimen of Rhodochrosite from a locality so obscure that it isn't even listed
mindat.org. The specimen was mined in the 1850's near the community of Voinic which is a
small municipality in north-central Croatia. The Rhodochrosite appear as rice-grain shaped
crystals tucked into the recesses of the dark matrix. A beautiful old time rarity from

Huge flattened and hoppered crystals of
Vanadinite in cluster!
This is a fascinating specimen, one that I've seen the likes of only a few times.
It's a cluster of elongated Vanadinite crystals that have formed what appears
to be a large fan-like crystal with hoppering on one side and lustrous smooth crystal
faces on the other. The specimen is in very good condition with only a few contacts
along the back side but nothing that detracts. The seam along the center has been
stabilized to strengthen the structure. A large, lustrous, and very aesthetic specimen!

lustrous crystal of Acanthite ps after Argentite!
We acquired a collection of this very large, super lustrous Acanthite crystals while in

formation as the Acanthite pseudomorphed the higher temperature Argentite. Exceptional

and very impressive plate of Orange Calcite scalenohedrons in cluster on Amethyst
A spectacular large cabinet sized centerpiece, the orange Calcites in the center are
deeply colored with
an intense flowing lustrous. They are completely orange and not coated orange and this is
not a color one
often sees in Calcite crystals. They're actually quite rare and this is the finest large
plate of this variety
that I've seen in a long time. In excellent condition across the entire length of the
plate with barely a scuff.

specimen of crystalline Native Copper with Quartz and Epidote!
Very high quality specimen displaying numerous sharp, well formed Copper crystals on all

Gorgeous pink-tipped green Elbaite
Tourmaline with Quartz!
The colors are a rich pastel and consistant throughout the gemmy interiors at top
to the more translucent interiors near the bottom. The termination is complex and
actually consists of several terminations coming together like a tight cluster. Very nice!

combo piece of Rhodochrosite with Calcite, Arsenopyrite, and Quartz crystals!
Very attractive specimen featuring a base of pink Rhodochrosite which serves as host for
Calcite octahedrons with lustrous Arsenopyrite and Quartz crystals. The crystals are clean
and free of contacting
and the combination is rather scarce. This is definately not a specimen that appears in
the marketplace very often
