Exceptional crystal of bi-colored
Precious Topaz sitting vertically on hard Calcite matrix!
Absolutely stunning crystal which measures in excess of 3.5 cm in length and
features a perfect
termination with glass-like clarity. The color of this Topaz can best be
described as a golden-pink which shifts to
a purer pink at the top half of its length. The crystal is brilliantly
glassy-lustrous and the color glows from within.
To find a crystal of this size and quality from Katlang is simply amazing. A
specimen worthy of the finest collection.
Locality: Shamozai, Katlang, Mardan
District, North-West Frontier Province, Pakistan.
Measures: 5.5 cm by 5.2 cm by 4.5 cm in size.
Comes with a custom
made, engraved display base

Spectacular Arrangement of Acanthite crystals rising atop white Quartz matrix!
This is one of the finest Acanthite specimens I've ever seen and is definately
amongst the best
examples I've seen from Morroco. Most Moroccan Acanthites have no matrix and are
pretty
clunky but these crystals have super sharp crystalization with a pyramidal form
and intense
luster. They measures to 2.5 cm in size and rise up off the surface in a
stacked, 3-dimensional
setting that is really aesthetic. I was thrilled to find this piece at the show.
In excellent condition.
Locality: Imiter Mine, Imiter
Mining District, Tinghir Province, Drâa-Tafilalet Region, Morocco.
Measures: 7.5 cm by 6.6 cm by 3.5 cm in total size.

Beautiful cabinet plate
featuring crystals of Native Sulfur atop white Aragonite covered
matrix!
The crystals are well formed and translucent to transparent with flashy,
lustrous faces. They
have been well served and protected by the structure of the Aragonite matrix
and protected
in recesses. In excellent condition overall with few contacts and a
beautifully trimmed matrix
framing a very bright, clean and visually pleasing cluster of Sulfur
crystals. One of my favorites.

Amazing old classic
featuring Azurite crystals standing vertically atop Limonite!
Circa 1890's, this specimen is both aesthetic and impressive. The large
Azurite crystals are isolated and sharp in habit.
They stand vertically inside a concave matrix of spotted Limonite and
exhibit jaw dropping glassy luster with good translucense.
The contrast between the brilliant blue Azurites and textured Limonite
is stunning. One of the finest Bisbee pieces I've ever seen.
Locality: Bisbee, Warren
District, Mule Mtns., Cochise County, Arizona.

Reddish-pink Fluorite crystals on Smoky
Quartz!
Pretty specimen of French Fluorite. I haven't seen many of these in the past
several years and this one is from an
older European collection that has just come to the market. The Fluorite is
gemmy with good form and lustrous faces
with some slight etching around the edges. The Quartz crystals are mostly on
the back side but poke out on both sides.
Locality: Les Droites, Chamonix, Chamonix-Mont-Blanc, Bonneville,
Haute-Savoie, Auvergne-Rhône-Alpes, France.

Rare and spectacular specimen of Native
Gold on Quartz matrix!
This incredible specimen is one of the finest and largest specimens I've
seen from the small
and pretty much obscure Gold discovered at the Olive Grove Prospect which I
am told was found
during the digging of a water well. This good sized specimen displays highly
lustrous, semi-crystalline
layers of richly colored Gold, both front and back, atop a small matrix of
white Quartz. Absolutely stunning.
Locality: Olive Grove Prospect, Mariposa County, California.
Measures: 4.8 cm by 4.3 cm by 1 cm in size.

Deep red crystals
of Proustite accented by Acanthite snug inside a deep matrix vug!
What an amazing, unique specimen of Silver Sulfide! The Proustite crystals
have been well protected by the
hard matrix vug and still maintain incredible eye catching color. The
Acanthite is darker and more metallic
in appearance, providing the perfect contrast to the reddish Proustite
crystal clusters. The surfaces of the
Proustites are mirror-reflective and the interiors are gemmy. Both are
accented by Calcites inside the vug.
The matrix is pink Rhodochrosite at top and opens in the very back side of
the vug, allowing light through.
Locality: Uchucchacua Mine, Oyon Province, Lima Department, Peru.
Measures: 6.6 cm by 9.2 cm by 4.7 cm in size.

Rare combination of lustrous
gray crystals of Acanthite on Calcite!
Cute miniature from the Valenciana Mine. I don't see many specimens from

Acanthites are sharp
and climb their way upwards between the gemmy to translucent and quite
glassy Calcites. Very nice!

Very impressive cluster of
large Galena cubes with raspberry Fluorite from the Elmwood Mine!
I don't see many Elmwood Galenas anymore and very seldom do I find a cluster
of this magnitude.
There must be several dozens lustrous cubes here, covering both the front
and back, with some
measuring to nearly 6 cm in size. Fluorite and a sprinkling of Sphalerite
crystals are mainly the
accenting crystals. The main attraction here are the mirror-bright Galenas!
In excellent condition.
