B-129 Barite $45 SOLD
Annabel
Lee Mine, Hardin County, Illinois
7
x 7.5 x 3.5 cm.
This
curious specimen features numerous sprays of the mineral Barite growing
inside of a vug in its matrix. The earth-colored matrix contrasts
nicely with the light-blue color of the Barite crystals. Another interesting
feature of this specimen is that the Barite crystals exhibit pale turquoise-green
fluorescence when lit by SWUV light. Good mineral specimens,
especially on matrix, from the Fluorite districts of Illinois are getting
hard to obtain now that the mines have all closed.

C-170 Calcite
on Fluorite $140
Minerva
#1 Mine, Hardin County, Illinois
13.5
x 9.6 x 5.5 cm.
A
silky and lustrous example of Calcite from the famed Fluorite mines of
Illinois. The best, and my favorite, feature of this large and showy specimen
is the way the Calcite has crystallized in the form of wheat-sheaf-like
bundles at its center, with a ring-like crust of white Barite in the center,
followed by fan-like groups of Calcite crystals forming a ring around
most of the specimen. This Calcite specimen also fluoresces a creamy-yellow
when lit by SWUV light. Good Calcites from this location are all
but impossible to find these days, as the mines have been closed for almost
a decade now.

F-165 Fluorite $80 SOLD
Annabel
Lee Mine, Hardin County, Illinois
10.2
x 8.8 x 7 cm.
This
cluster of Fluorite crystals exhibit a rich purple color with a blue core
that is very pleasing to the eye. This specimen has been backlit
just a little bit to illustrate the color zoning. This colorful
specimen is contacted on the bottom and has a concave backside that features
a piece of the matrix that it formed on. Nonetheless this specimen
presents well.

Q-211 Quartz
variety Amethyst $85 SOLD
(ex. Russ Rizzo collection)
Comstock
District, Storey County, Nevada
6.4
x 4 x 2.9 cm.
The
Comstock Lode achieved fame for the enormous volume of Silver that was
mined there during the mid 1800's. Very few examples of the Silver ore
specimens or other associated minerals such as this Amethyst specimen
were preserved. While single crystals are occasionally found on
the mine dumps and surrounding hills by local collectors it is indeed
a rare occasion that an intact cluster of crystals such as this one is
found.

V-017 Manganoan
Vesuvianite $125
Jeffrey
Quarry, Asbestos, Québec, Canada
2.5
x 1.9 x 1.9 cm.
First off let me say that the photo of this specimen does not even come
close to doing it justice. The crystals of this specimen have
an eye-pleasing, grape-juice-like purple color with several of the crystals
showing hints of magenta inside of their greenish-yellow terminations. When
illuminated with SWUV light, the crystals on this specimen fluoresce a
good orange color. The Jeffrey Quarry has long been known to produce
excellent mineral specimens. Good specimens of Manganoan Vesuvianite
from this classic location are rarely found these days as the mine is
mostly inactive and the lower levels are filling with water.
