VERY RARE!! Amazing combination of Native Silver crystals on olive-green Chlorargyrite var. Embolite!
Both sit atop a matrix of orange Limonite. This is the only specimen of this combination that I've ever seen
and they are extremely rare from all localities. Using a 10X loupe, you literally see hundreds of lustrous
Silver crystals and some fine Silver wires sitting atop and between green crystals of Embolite! This is
truly a  rare opportunity to acquire a mineral conbination that very few collectors have ever owned.
From the Broken Hill Mine in New South Wales, Australia.
Measures 5.2 cm by 7.5 cm by 3.5 cm in total size.

Lustrous specimen of Mimetite from the famed San Pedro Corralitos!
This is a very 3-dimensional specimen as the photo indicates. There are two layers of Mimetite
here, both displaying satiny, lustrous surfaces and they cover the matrix as it opens up in the middle.
The specimen has a few very minor contacts along the upper edge but these are very difficult to see
and don't detract. The matrix edge on the upper level has been stabilized to prevent any shedding.
From the Congreso-Leon Mine, San Pedro Corralitos, Mun. de Casas Grandes, Chihuahua, Mexico.

SUPERB!! Sharp crystals of Acanthite and curling Native Silver wires!
Both Silver minerals sit atop a matrix of Quartz with Quartz crystal sprays.
The Acanthite crystals are so incredibly sharp and lustrous that at first glance, one
might not even notice the small "ram's horn" Silver located on the far right side of
the specimen! Acanthite and Silver combos from Mexico are rarely seen at the shows.

Measures 5 cm by 3 cm by 2.5 cm in total size.
Price $2850

Beautiful, vibrant sea-green crystals of Cuprian Adamite with Calcite in Limonite seams!
The color of these crystals is what makes the piece and it's incredible! The Cuprian Adamites
are sharp and glassy and contrast wonderfully with the sparkling Calcite which outlines the
seams on all levels. The specimen is in excellent shape with some matrix strengthening
(stabilization) on the backside. I count at least a dozen of the colorful Adamite crystals.

Exceptional, very sculptural specimen of large Native Copper crystals with a Malachite coating!
The contrast between the Malachite and original Copper patina is gorgeous. This is one of my favorite

LARGE CABINET!! Incredible specimen hosting two large Selenite crystals on Goethite!
One of the most impressive Selenites at the entire show, this specimen features two doubly terminated
Selenites measuring nearly 22 cm and 16.5 cm in size! Both crystals are incredibly clear and glassy with
well striated surfaces that reflect the light with an intense luster. For a soft mineral of such large size, this
specimen is in amazing condition with only a few trivial contacts. This could easily be a museum piece or a
wonderful centerpiece for a personal mineral collection. If you'd like a stand, I can have one made for you.

lustrous, measuring nearly 4 cm across the front. A smaller sidecart crystal is incomplete
