VERY rich specimen of Native Silver leaves with Acanthite in and on white Quartz matrix!
This is a heavy cabinet sized specimen that is loaded with Native Silver. The Silver appears in a mosaic-style pattern
in the stark white Quartz matrix. The leaf structure is probably the result of the host matrix and most are quite angular in
appearance. This locality was mined 1905-1971 and produced about 7,000,000 ounces of Silver. A great looking, historic Silver!
Locality: Penn Canadian Mine (Glen Lake Mine), Cobalt area, Cobalt-Gowganda region, Timiskaming District, Ontario, Canada.
Measures: 8.4 cm by 11.7 cm by 6.2 cm in total size.

Unique and bizarre specimen of a broken brown bottle with Selenite crystal overgrowth!
This is one of the oddest specimens I've seen from the Tsumeb Mine. It's obviously post-mining as an old glass
bottle was left inside the mine by a miner, broken, and then overgrown by Selenite crystals which grew over and
around the broken glass, holding the various pieces together. The brown bottle sits upright by itself and appear to
have been round as the bottom is ringed and mostly intact. The Selenite crystals are in excellent condition and
exhibit a flashy luster when the specimen is rotated side to side. Very nice and definately a conversation piece.

Green-tipped crystals of Quartz with Dolomite accenting, a Calcite cluster and Chalcopyrite on matrix!
I love the display this specimen offers, with its fat Quartz crystals that taper perfectly to a light green
tip. I suspect the green coloration is an inclusion of Chlorite. Inside the green tips are multiple phantoms
which are very noticeable under lighting. The Quartz crystals are accented along the back faces by dozens
of Dolomite crystals. This is topped off by a 3.5 cm Calcite cluster and golden Chalcopyrite. No detractions.

This lovely work of nature is a perfect display of contrasting colors and surface textures. It's in
excellent condition with no detractions. The Quartz is terminated at top with a matrix influenced
back side and a cluster of Quartz crystals sprouting up around the bottom. Gemmy and flashy!

Good looking plate of Galena cubes with Sphalerite crystals on Chert matrix!
This is a well balanced specimen from the classic Tri-State Mining District. I've always had an appreciation
for these old timers and this fine cabinet plate features lustrous Galenas to 3.5 cm in size. Reddish-brown
Sphalerites frame the borders at both the top and bottom. In excellent condition with great flash and eye appeal.

Large cabinet plate of forest green Fluorite crystals appearing as botryoidal surfaces on matrix!
This is a new find that is different than anything else I've seen from China. The crystals are small and gemmy
with a different shade of green. Under magnification I can see dozens of lustrous, stepped angular faces but
the crystals all come together to complete the botryoidal, rolling surfaces. This was one of the prettiest plates
from the new find in China. In excellent condition with an unusual color covered by rolling  luster and flash.

One's eye is immediately drawn to the absolutely pristine Calcite twin along the top left.

crystals of varying habit accompany the twinned crystal and all sit atop a matrix which is
covered by small golden Calcites. In excellent condition save for one nearly invisible cleave.
