Tucson2014-255SilverChina76mm.jpg (212633 bytes)

MIN#EXCEPTIONAL-61 SOLD!

Very aesthetic specimen of Native Wire Silver rising up above a Native Silver matrix!
Stunning specimen of Native Silver in true arborescent style. I can't imagine a more attractive, tree-like
Native Silver from China. The wires of this specimen are perfectly balanced in size and position. They sit
atop a matrix that is a mix of wires and massive Silver and all of the main vertical wires seem to originate
from a central point or "trunk". The patina is a lovely soft, almost iridescent color over lustrous surfaces.
From Yueshan Ag-Pb-Zn deposit, Huangtun Township, Lujiang Co., Hefei Prefecture, Anhui Province, China
Measures 8 cm by 7 cm by 2.4 cm in total size.

Tucson2015-304TanzaniteMerelaniTanzania49mm.jpg (260468 bytes)

MIN#EXCEPTIONAL-62 NEW!

Large crystal of terminated Tanzanite on matrix!
This is one of the first Tanzanite matrix specimens to appear in America I am told. It was acquired
in the 1970's by famed collector F. J. Barlow and was a major addition to his collection at that time
because Tanzanites, and especially matrix Tanzanite, were pretty much making their initial splash
after the stone was only just discovered in 1967. This is an impressive stone and was probably one
of the finest examples at that time although much larger specimens have since come to market. It
displays a perfect textbook termination and is unheated so the trichroic properties are fully present.
The stone itself measures just shy of 4 cm tall at 3.8 cm by 2.1 cm by 2.1 cm in total size. It is gemmy
but does display some of the common internal crazing. It sits atop a matrix of Calcite and Zoisite.
This is a good looking matrix Tanzanite but the fact that it was one of the first to come to America and
its famous provenance make it historically significant. It is also pictured under Tanzanite on Wikipedia.
From the Merelani Hills (Mererani), Lelatema Mts, Simanjiro District, Manyara Region, Tanzania.
Measures 4.8 cm by 3.5 cm by 3.8 cm in total size.

Tucson2016-130ScheeliteApatiteMtXuebaodingChina81mm.jpg (351441 bytes)

MIN#EXCEPTIONAL-63 SOLD!

Rare combination featuring two gemmy Scheelite crystals with a Pink Apatite on Muscovite!
A gorgeous pairing, a small find of this unusual combination was discovered about a dozen years
ago in China and to my knowledge has not been repeated. This specimen is undoubtedly from that
find and is the first Scheelite-Pink Apatite specimen I've seen in a very long time. The Scheelites
are bright, gemmy, and vibrant orange with very glassy lustrous surfaces. The Apatite is a lovely
rosy-pink with sharp crystal form and a great positioning in the foreground. In excellent condition.
From Mt Xuebaoding, Pingwu Co., Mianyang Prefecture, Sichuan Province, China.

Denver2010-145AquamarineMtXuebaodingChina12cm.jpg (203667 bytes)

MIN#EXCEPTIONAL-64 SOLD!

Gorgeous, glassy tabular crystals of Aquamarine with Muscovite!
This plate has a wonderful flash to it and the color of the Aquamarine crystals is much better
than what normally comes from this locale! I would place the depth of blue on par with the Aquamarines
one sees coming out of Afghanistan and that's pretty good for a Chinese specimen. The tabular crystals
are glassy and translucent with some gem. No real damage to speak of - only some bumps at the trimming.

MIN#EXCEPTIONAL-65 NEW!

New find featuring a deep Golden Calcite crystal with Hematite on smaller Golden Calcite crystals!
The crystals are deeply colored and gemmy. The reddish patches are Hematite accents atop earlier
surfaces which have now been mostly overgrown, coloring the Calcite internally. In pristine condition.

Tucson2016-123ChromiumPetrifiedWoodnearWinslowArizonaB.jpg (408869 bytes)

MIN#EXCEPTIONAL-66 SOLD!

Exceptional Petrified cross section of Chromium colored wood (Araucarioxylon arizonicum)!
From one of the oddest finds of Petrified wood in the world, this Conifer tree existed between
65 and 200 million years ago during the Triassic Era. When the tree died and was becoming
petrified, it became exposed to the mineral Chromium (same mineral which colors Emeralds).
Native Americans were the first to find the material and used it in jewelry making but kept the
location a secret until it was eventually rediscovered and authenticated by the Smithsonian.
These specimens are natural hygrometers. When dry they become a very light pale green and
when wet or exposed to humidity they turn a deep green. This specimen is a very fine example,
cut into a cross section and displays a full rind of bark around both ends which are highly polished.
From a locality near Winslow, Navajo County, Arizona.
Measures 7 cm by 9.4 cm by 2.5 cm (1 inch) in thickness!

MIN#EXCEPTIONAL-67 NEW!

Superb glossy, iridescent blades of Covellite with Pyrite crystal accenting!
One of the finest Covellites I've seen from this classic locality, this is the second time I've had
the honor of offering this beautiful specimen. The bladed crystals are sharp and super lustrous
with a brilliance I rarely see in a Covellite specimen. The color is very iridescent with vibrant blues
and reddish-purples throughout. Atop and between many of the standing blades are flattened crystals
of golden Pyrite. Visually, this specimen is stunning and the edges are complete with minor contacting.

Tucson2011-196SilverSchlemaGermany7cmB.jpg (368148 bytes)

MIN#EXCEPTIONAL-69 NEW!

Exceptional specimen of Native Wire Silver atop a matrix of massive Silver!
This incredible specimen hails from the obscure Shaft #66 in Schlema! I'm told that this shaft is
actually located near the center of town and that specimens from there are quite rare. The wires pop
up from a matrix that is mostly massive Silver and thin wires intertwined with small bits of Calcite.
The wires that rise upwards are more like knarled ropes and they are all very stable. This is
easily one of the finest Schlema Silvers I've seen in a long time and would make a wonderful
addition to a Silver specimen suite or European mineral collection. Superb, aesthetic small cab!
From Shaft #66, Schlema, Schlema-Hartenstein District, Erzgebirge, Saxony, Germany.
Measures 5 cm by 7.4 cm by 4.2 cm in total size.

MIN#EXCEPTIONAL-70 NEW!

Brilliant, flashy crystals of deep green Uvite Tourmaline in cluster with Quartz and Magnesite!
This beauty can be displayed from either side because the crystals are just as perfect and
glassy-lustrous on both the front and the back. There are no visible contacts but the front
side displayed in the above photograph does have two small crystal-clear Quartz points
while the back side displays a scattering of Magnesite crystals among the green Uvites.

MIN#EXCEPTIONAL-71 SOLD!

Exceptional cabinet plate of brilliant, dazzling Arsenian Pyromorphite!
For its size, this is one of the finest Pyromorphite plates I've acquired recently. I'm very happy
to say that this is the second time I've had the pleasure of being able to offer this fine specimen
and it is truly worthy of a high quality mineral collection. The surfaces are incredibly lustrous and
almost blinding from the amount of light which rolls across the rounded crystal surfaces. There is
barely a contact anywhere and the specimen is beautifully trimmed around the edges. Very nice!

Tucson2015-224GalenaCalciteStalactiteGjudurskaMineBulgaria15cm.jpg (280853 bytes)

MIN#EXCEPTIONAL-72 SOLD!

Extremely rare Galena stalactite topped by Calcite crystals!
This incredible specimen was collected by Ross Lillie and he tells me only a few specimens
of this calibre were ever found. I've never seen a Galena stalactite of this form or size before
so I was amazed when I discovered the specimen at the show. The Galena is highly lustrous and
mirror-reflective in areas. The crystal form is elongated of course, but the look of the stalactite is
different from those smaller ones found in Missouri. The surface is more smooth and appears to
flow upwards like liquid with rounded crystal faces. At the top are numerous blades of Calcite which
formed after the stalactite had completed its formation. A rare opportunity to acquire something unique!

MIN#EXCEPTIONAL-73 NEW!

Classic rarity! Fine crystals of Calcite on matrix from St. Andreasberg!
This locality was an old Silver Mining District in Germany but today all the mines are long
since closed and reclaimed for the most part. I don't come across many fine Calcite plates
from this locality and all date back to the late 1800's or early 1900's. This plate consists of
dozens of translucent, stacked Calcite crystals which formed scalendohedral-like pillars atop
the Sulfide mineral and Dolomite covered surface. Beautifully preserved with few contacts.

MIN#EXCEPTIONAL-74 NEW!

HISTORICAL AND EXTREMELY RARE!!
Museum plate of Pyrargyrite crystals with Acanthite and Quartz from Tonopah, Nevada!
An unbelievable find!!! This specimen was presented as a gift to the Philadelphia Academy in 1915 by
the Tonopah-Belmont Mining Company and has not been touched or messed with since it was found in the
mine pocket nearly 100 years ago. Large cabinet in size, this is a true relic from the earliest Silver mining
history of Nevada and represents the largest and finest specimen that I've ever seen from Tonopah or
any other locale in Nevada for that matter. The plate features dozens of shiny, lustrous Pyrargyrite
crystals with Acanthite and white Quartz points. There's a good deal of color remaining in these ruby-silvers
and many of the Pyrargyrites show red under normal lighting A direct spotlight really brings out the color!
Obviously this cabinet sized plate has been well protected during its many decades in the Academy!
Measures 16 cm by 19 cm by 6 cm in total size.

Very impressive specimen of crystalline Native Copper growing upwards atop a Copper base!
This specimen is amazing. It's from the White Pine, the same locality as the exceptional Native Silver
at the top of this webpage, and it is just as impressive in its own right. The Native Copper crystals
climbed upwards to a height (22 cm) that is unlike anything I've seen from this locality! It's so tall that it
almost wouldn't fit on the page. The surfaces are lustrous and covered by a lovely reddish-brown patina.

MIN#EXCEPTIONAL-79 NEW!

Super lustrous and quite unique specimen of Smithsonite with orange caps!
I call this specimen tri-colored because you have three distinct layers of growth and coloration
displayed here. The first is a powder-blue layer which covers the underlying matrix. The second
is a more lustrous white layer. The third and final layer is a very lustrous orange colored Cadmium
Smithsonite which appears as a top cap draped over the lower two layers. The end result is one of
the most unique looking and interesting specimens of Smithsonite that I've seen in recent years.
