EXCEPTIONAL!!! Museum quality plate of
intensely lustrous Schorl crystal clusters on white Quartz!
These incredible Schorl specimens appeared about 7 years ago in Tucson and have all but
disappeared
from the market. I purchased this large cabinet plate in 2006 because it was the largest
of the entire lot
that I was fortunate enough to cherry-pick. It's now making its first website appearance
and trust me,
the above photo (as good as it may be) does not do the specimen justice! The Schorl
Tourmaline
clusters are incredibly vibrant and lustrous with a satiny sheen that just can't be
captured in a photo.
These black crystal clusters are made even more impressive by the stark-white Quartz
crystal
matrix that they sit on. This is the finest and largest specimen of this material that
I've ever owned
or offered on the website. It would easily make a great centerpiece for the finest mineral
collection.
From the Guadalupana Mine, Cerro de Chavito, Santa Cruz, Sonora, Mexico.
Measures 19 cm by 24.1 cm by 8 cm in size.

Fine specimen of crystalline Native
Copper in a dendritic "fan" formation!
This is both an unusual and very attractive Copper
specimen. I've only seen a few like it and this is the
better of them. Each part of the "fan" is composed of smaller crystals
climbing upwards from the center.
From the Keweenaw Peninsula. Michigan.
Measures 4.3 cm by 3.5 cm in size.

County, Colorado.

Unique specimen of Native Copper in
sheet form atop Native Copper crystals!
What a strange Copper! The Copper sheet extends all
the way from one end to
the other and was later covered by the small crystals. I've not seen another like
it!

Large, shiny-black crystal of
Sphalerite with Calcite and Quartz crystals!
This is one impressive looking Sphalerite! The faces
are super sharp and glossy black
with distinct striations. There is some incompleteness on the backside out of view where
the
crystal was removed from the host matrix but this does not detract. The front side is
perfect.
From the Trepca Complex, Trepca Valley, Kosovska
Mitrovica, Kosovo.
Measures 11 cm by 10.2 cm by 6.5 cm in size.
Mined circa 1920's - Formally in the British National Museum

Large cabinet plate of well
defined Blackjack Sphalerite crystals and Dolomite on Chert matrix!
This specimen is as impressive as it is large! The crystals are sharp with a satiny luster
and
cover the entire Chert matrix from one side to the other. Dolomite crystals peak out from
beneath
the smaller Sphalerites. The variation in crystal size gives the specimen a really nice
appearance
and allows for the large Sphalerites to look more isolated even though the crystal
coverage is total.
From the Tri-State Mining District, Treece, Cherokee County, Kansas.
Measures 16 cm by 28 cm by 9.2 cm in total size.
