Rare, giant botryoidal fluorite.
This is a very unique fluorite. It comes from the vicinity of the
famous De An Mine in Wushan, Jiangxi Province, China. You've seen the
Indian botryoidal fluorite, yellow, once in a while red, maybe an inch
across. But look at this!!! A huge botryoidal form, 3 inches wide, 2
inches high and 1 5/8 deep (7.5 X 5 X 4 cm). There was a very small
group of these sold at Tucson this year. Some of them were up to 5 or 6
inches. You can see some
others at Rob Lavinsky's site
(http://www.irocks.com/TUCSON07china1.html - while you're there you can
see Da Ye calcite, then look at my example of Da Ye calcite!). Get one
of these while you can. Depending on the exact color
temperature of the light you use this looks purple to blue. The surface
is matte. If you get some light behind it, very pretty. If it is front
or top lit, not bad and very unique for the size in this form. Click on the picture for a series of other

Fantastic octahedral form, with strange,
complex terminations.
This is a very unique galena from Reynolds County, MO, probably the
Sweetwater mine, octahedral with cubic faces on the
terminations. These flattened terminations show complex "hoppering" as
the photos show. There is partial covering of quartz on some of the
crystals and there is micro chalcopyrite scattered about. The big
crystal of galena is 1 inch across! The whole specimen is about 2 3/4 X
2 inches (7 X 5 cm). Very cool!

The
specimen has a mass of interconnected,
rounded crystals of copper. One side has a lot of a copper
mineral,
probably malachite, delightful color
contrast, very fine. 7.5 cm (3 inches) tall, with a nice little stand
that sets it upright.
These copper crystals are from the world famous Central Mine. Here is a
great opportunity to add some choice copper
crystals to your collection. The Central was one of the greatest
fissure mines that opened in the Michigan Mining District. It operated
from 1854 to 1898 and produced over 50 million pounds of copper.
Nice Yellow Fluorite.
The color is good on this southern Illinois fluorite, more of a lemon
yellow than the usual
dull orange yellow one sees. The back is very interesting, showing
scalloped casts where barite has dissolved away after formation of the
fluorite that once covered it. I got this a number of years ago from
Douglass Minerals and it includes that label. The face of this is
beautiful and highly translucent. to transparent. The dimensions are
9.5 X 5 X 4 cm (3 3/4 X 2 inches).

Rare
Location, fine fluorite. From Leidan, Guizhou Province, China.
I acquired this specimen from Peter
Seroka, a famous German mineral collector and fluorite specialist; it
comes with his label. For those of you interested in fluorite, you
should try to get a copy of Peter's book Fluorit: Daten Fakten
Weltweite Vorkommen (roughly, Fluorite, World-wide localities). It's a
big three-ring bound collection of all the known fluorite localities
world wide, plus detailed drawings of all the possible crystal forms of
fluorite. A very ambitious project. The specimen is about an inch thick
(2.5 cm) and about 4 X 3 inches (10 X 8 cm). The fluorites have good
transparency and there are little pyrites here and there.

Calcite on Calcite on Matrix.
The Ezhou Prefecture, Daye, Hubei, China has produced small finds of
extremely fine calcite specimens, including many twins. This is a very
fine example from a find in 2005. Much of this material was
unfortunately scraped or dinged by the time it reached shows and retail
mineral shops. I selected this and a few other specimens for their
perfection. This is a splendid group of twinned crystals up to 3.5 cm
on a bed of smaller calcites on an interesting matrix of dolomitic
limestone, hematite and sulphides.
The specimen is 8.5 X 6 X 4 cm. The crystals are absolutely perfect on
all sides. The crystals glow with light and are highly translucent,
tinged with internal veils of included hematite. This is a
pink/orange/red hematite, not the dingy brown that is common. Also,
there is good translucency to the crystals, as I tried to show in the
backlit photos.
