Amethyst Scepter
Specimen #W0801
Ankadilalana Mine
Antananarivo Province
Madagascar
2.4 x 0.6 x 0.6cm
Thumbnail
$45

To kick off my first update of 2008 that incorporates a multitude of specimens from all around this incredible world of ours, I've chosen a very attractive specimen of quartz var. amethyst.  Quartz being one of the most common, abundant and extremely variable specimens of the mineral world, is a species that never ceases to amaze me. 

This specimen is a wonderful example of the variety of quartz specimens that mother nature produces.  It's an intact scepter with wonderful color and form. No damage.

Enjoy this update and I hope you like it as much as I enjoyed putting it together. 

Na Zdorovie!










Beryl var Emerald
Specimen #W0802
Muzo Mine
Vasquez-Yacopi Mining District
Boyaca Department
Columbia
4.8
x 2.0 x 1.8cm
Large Miniature
$50

Here's an attractive emerald specimen from one of the best producing locals in the world. It's made up of a number of interlaced opaque emerald green xls on matrix.  Nice piece!












Cactus Quartz var Amethyst
Specimen #W0803
Magaliesberg Mtn. Range
Kwa Ndebele
South Africa
5.8 x 4.2 x 2.3cm
Small Cabinet
$75

Here's a very nice cactus quartz piece from South Africa.  The quartz xls display a wonderful "amethyst" or purple color along with a bit of "smokiness" along the top edge of the specimen.  There are a few trivial dings here and there on the edges of the specimen, but they are only really noticeable under magnification.  A very nice specimen in my humble opinion!











Calcite 
Specimen #W0804
Lavrion
Lavrion District Mines
Lavrion District
Attikí Prefecture
Greece
6.3 x 5.8 x 5.7cm
Small Cabinet
$195
Mildly Fluorescent

There's a WHOLE lot going on with this specimen.  First..... It's made up of  a base matrix that is literally covered by heavily altered calcite scalenohedral and arborescent xls.  They vary from ice cube clear, to frosty white, to a ghostly pale blue color.  The ice blue color is awesome! Scattered about in many of the nooks and crevices of this specimen are small green acicular to botryoidal blobs of what I believe to malachite.  Their are a few of these "blobs" that could possibly be Cuprian Adamite or Annabergite, but I could not say for sure even under 10x magnification.  This local is known for both of these species.  There is also a small deposition of azurite xls that I just came across.  Lastly, there are a number of brownish-red or rust colored xl growths scattered about which I cannot identify.  The more I look at this specimen, the more I like it.  It is one COOL piece of Mother Nature!













Calcite, Pyrite & Stilbite
Specimen #W0805
Rudny
Kustanay Oblast
Kazakhstan
7.7 x 6.7 x 2.4cm
Small Cabinet
$125
Mildly Fluorescent

Here's another really COOL rock.  It consists of a mass of calcite xls that have been etched to reveal a underlayment of pyrite xls.  Many of the calcite xls that were not etched display "slivers" of pyrite xls, i.e. they're included with the pyrite.  The picture below this clearly shows the inclusion.  The stilbite xls are milky to brownish white and add a nice contrast to this very interesting piece.  No discernible damage.












Corundum (polychrome) var. Ruby
Specimen #W0806
Ambahatraso
Ihosy
Madagascar
6.5 x 5.1 x 4.1cm
Small Cabinet
$250

I absolutely love the color of this ruby!  It is bi-colored or polychrome.  The xl is fully terminated, measures 1.1x0.9cm, and is undamaged.  It sits atop a metamorphic base which provides a very nice color contrast.  The xl displays a bit of geminess and did I mention the color?  WOW!












Fluorite, Galena & Barite
Specimen #W0807
Bingham
Socorro County
New Mexico
8.0 x 6.4 x 2.8cm
Small Cabinet
$75
ex Don Belsher collection

Here's a very colorful and showy specimen from New Mexico.  You could display it from either side as each one is covered with numerous cubic fluorite xls to 8mm.  The fluorite xls range in color from pale lavender to pale blue and are virtually damage free.  In addition to the fluorite there are a number of galena xls scattered about.  It appears to me that the galena is replacing the fluorite.  Lastly there is one one larger (2.2x1.6cm) barite blade with a number of smaller blades scattered about.  Nice rock! 

Please note - My pictures turned out a bit darker than the actual color of the specimen. The fluorite xls are not quite that dark (at least on my monitor).













Fluorite
Specimen #W0808
Grant County prospect
Bound Ranch District
Grant County
New Mexico
16.5 x 9.3 x 6.5cm
Large Cabinet

Here's a excellent example of the gorgeous green translucent octahedrons of fluorite from Grant County that have a look all their own. They have a smooth, glass like surface and almost look melted together. They really light up and glow a beautiful green color under good light! These xls have formed on a rather large chunk of matrix giving it some heft.  (1lb 13oz or .815kg = higher shipping costs)











Galena on Barite
Specimen #W0809
Julcani District
Angaraes Province
Huancavelica Department
Peru
4.8 x 3.8 x 2.7cm
Large Miniature
$35

This specimen is made up of a number of milky white bladed barite xls nestled in between two modified galena cubes.  The barite blades are intact while the galena have a "pitted" look to them.  A rather interesting and attractive mineral specimen!












Goethite 
Specimen #W0810
Dachang mine
Qinglong County
Guizhou Province
China
11.2 x 2.2 x 2.0cm
Cabinet
$250
New Find

This is one unusual piece, in my estimation.  It comes from a new find in China.  It's either a stalactite or stalagmite.  I'd vote for stalactite, but you can't really tell.  Goethite is commonly found in iron ore deposits and up until now, I had never seen it in this form. It varies in color from a dull metallic look to very iridescent.  This is probably my favorite piece in this update!
