PYRO1 - Pyromorphite
$ 275.00 SOLD
Yangshu, Guangxi Province, China
miniature - 8.5 x 5.6 x 1.5 cm
This piece shows a deep leafy green with bright reflection off the crystal faces. It was mined in the 1990's and comes from John Rakovan's personal collection. (Professor of Mineralogy at Miami University in Oxford, Ohio. His label is included).

SPHALERITE1 - Sphalerite on Quartz
$ 375.00
Shuikoushan Lead/Zinc Mine, Chaling, Hunan Province, China
cabinet - 11.5 x 8 x 6 cm
Two very large Sphalerite crystals are pleasantly perched on a bed of clear Quartz crystals. On top of the Sphalerites are water clear Drusy Quartz crystal clusters. This piece is aesthetic, especially in its contrast. The dark orangey Sphalerites vs. the white/clear quartz. The Sphalerites are relatively rounded, vs. the Quartz pointiness. And finally the tiny, fine druzy clear Quartz contrasts the larger cluster of points. It's in good condition overall. There's a minor blemish on the far right side of the lower Sphalerite crystal. Comes with a 1.25 inch three-prong acrylic stand.

CREEDITE1 - Creedite on Rhyolite
$ 125.00 SOLD
Abasolo Mine, Navidad, Durango, Mexico
small cabinet - 7 x 5.2 x 5.3 cm
This Creedite is neatly perched on a matrix of Rhyolitic host rock. Most Creedite specimens are not on matrix, and are commonly damaged. This one is in excellent condition. Creedites are found in a highly mineralized clay (that affects their color), within a Breccia Pipe, that had injected hot solution that later crystallized as Creedite. Mining these is fraught with danger, as cave-ins are quite common, and have finished recent production (according to Mike New).

PHENAKITE1 - Phenakite
$ 135.00 SOLD
San Miguel de Piracicaba, Minas Gerais, Brazil
thumbnail - 3.1 x 2.1 x 2.7 cm
This is large for Phenakite crystals I have seen over the last 20 years. It was mined prior to 1970 (probably much earlier, but not sure). It is a classic "fan," shape with good crystal faces. There's no visible dings, and the bottom is contact with another crystal (not broken).

QUARTZ4 - Quartz var. Amethyst "flower"
$ 160.00 SOLD
Irai, Rio Grande do Sul, Brazil
cabinet - 13 x 9 x 3 cm
In the same general area of the Amethyst geodes from southern Brazil, there is another deposit that produces elegant Amethyst "flowers," like this one. They form in basalt (ancient volcanic flows), with very little room to crystallize. the result are thin 'sheets' of Quartz that catch the light and add attractive vertical composition to your collection. This piece is in excellent condition, and displays a range of color from clear to a moderate purple/lavender.

OLMIITE2 - Olmiite on matrix
$ 395.00
N Chwanning II Mine, Kuruman, Republic of South Africa
small cabinet - 5.2 x 4 2.7 cm

QUARTZ3 - Quartz with Blue Fluorite inclusions (hand polished)
$ 135.00 SOLD
Miandrivazo Province, Madagascar
thumbnail - 7.8 x 1.7 x 1.4 cm
This is an excellent example of the limited find of prismatic Quartz crystals with small blue Fluorite crystals included within them. All of the crystals found, were in frosty Quartz, such that polishing really enabled a proper view at what these extraordinary. This is a bright crystal, with the fluorites well positioned in the top third of the crystal for easy viewing in a showcase. Although you can't see it without a hand lens, there is a miniscule chip off the backside of the termination.

QUARTZ2 - Quartz aka "Spirit Quartz"
$ 95.00
Near Pretoria, South Africa
thumbnail - 9.0 x 9.6 x 7 cm
Spirit Quartz is found in South Africa. It's unusual in that drusy Amethyst grows over an opaque Quartz shaft, thus creating a sparkly, cactus-like specimen. I learned with considerable glee, that this Quartz was not named "Spirit Quartz," because of any isoteric, or transcendental reasons. The African miners named it Spirit Quartz because when they found the good color (a rich purple) they could then get paid and buy some of the readily available "mentholated Spirits," at the local liquor store. Apparently both Spirit Quartz and Mentholated spirits have the same purple color!
This piece is aesthetic and has crystals that are on average 9 cm (3 1/2 inches) long. It displays well, and is in good condition. Unseen from the displayable angle, on the back there is a patch where some of the drusy Amethyst came off, thus exposing the primary Quartz shaft, probably when it was extracted.

SIKHOTE1 - Sikhote-Alin Meteorite
$ 125.00 SOLD
Sikhote-Alin Mountains, Eastern Siberia, Russia
miniature - 5 x 4 x 1.7 cm
This iron meteorite fell on Feb. 12, 1947 in the Sikhote-alin Mountains of Eastern Siberia, Russia. It is the largest observed meteorite fall in history, with over 23000 kg raining down on the earth in the form of iron shrapnel and the more rare individual fallen meteorites such as this one. It is covered in regmaglypts, the indentations that give the piece contours. I put this piece away, back when this meteorite was readily available on the market. A couple years ago, the Russian government has made it difficult to export, and diggers I knew said there was almost nothing left to find. It weighs 49.6 grams.

LINAR1 - Linarite, Galena on Quartz
$ 45.00 SOLD
Sunshine #2 Mine, Hansonburg Mining District, Bingham, New Mexico
miniature - 3.5 x 2.5 x 1.6 cm
This is actually Anglesite and Brochantite psuedomorph after Linarite, however there is also Linarite on Galena present. Sound complex? It comes out of the John Rakovan collection (professor of geology at Miami of Ohio in Oxford), his label is included (pic #3). John spent a lot of time and numerous studies at this locality, and is quite the expert.

AMETHYST1 - Quartz var. Amethyst with Hematite Incl.
$ 285.00 NET
Goboboseb Mtns. Brandberg Dist. Erongo Region, Namibia
small cabinet - 6 x 8 x 5 cm
This dynamic cluster of Amethyst has crystals directed in several different directions, making it eye-catching. There is a bit of "smoke," in the primary crystal, which adds additional character to the piece. Crystals from this area are often misidentified as being from "Brandberg, Namibia," which is actually a deposit within a nature preserve in the same district. The Goboboseb mountains, in the Erongo region from which this cluster was found, is know for its remoteness, as the nearest water source is over 35 kilometers away. Near the base of the cluster, are needles of hematite, which occur occasionally in Quartz from this deposit. It is in excellent condition, with only the back-projecting crystal having been broken in the pocket and rehealed.

DIOPSIDE1 - Diopside
$ 195.00 SOLD
Merelani Mine, Lelatema Mountains, Arusha Region, Tanzania
thumbnail - 1 x 1 x 1 cm
Gem Diopside crystals from the Tanzanite mines in Tanzania are a relatively new item on the market. They tend to be small, with the best quality ones being bright green and glassy. This gemmy diopside has an electric "glowing" green that is so striking. It has a wonderful multi-face termination, brilliant color and internal clarity as well. This piece will add great color to your display. It weighs 1.35 grams (over 6.5 carats). An impressive article about this deposit was printed in the Mineralogical Record in September-October 2009 (the "Tanzanite Issue").

DIOPSIDE2 - Diopside
$ 195.00
Merelani Mine, Lelatema Mountains, Arusha Region, Tanzania
thumbnail - 2.2 x .8 x .5 cm
Gem Diopside crystals from the Tanzanite mines in Tanzania are a relatively new item on the market. They tend to be small, with the best quality ones being bright green and glassy. This piece has an excellent, rich color. It is nearly an inch long and has a smaller crystal that has joined the primary that adds character to the overall crystal. It weighs 1.7 grams (8.5 carats). An impressive article about the deposit was printed in the Mineralogical Record in September-October 2009 (the "Tanzanite Issue").

SERANDITE1 - Serandite with Aegirine
$ 175.00
Mont St. Hilaire, Quebec, Canada
thumbnail - 1.7 x 2 x 1.2 cm
This lovely Serandite is a floater crystal, and has an embedded Aegerine in the top that adds contrast to this richly colored mineral. For its size, this piece is top notch. The mines in Mont St. Hilaire are all closed, and sadly pieces such as this one are irreplaceable. It comes in a thumbnail box, with its original hand written label, assembled by famed thumbnail collector Wendy Melanson of Hawthorneden Inc.

CUPRO1 - Cuproadamite
$ 395.00
Ojuela Mine, Mapimi, Durango, Mexico
miniature - 2.6 x 3.5 x 2.1 cm
This was the best piece in a high-grade lot of about 40 pieces I acquired, shortly after it was mined. The rare production occurred, following the drought in Mexico (fall of '08) that lowered the water level in the Ojuela Mine below the Adamite level for the first time in about 20 years. I love this piece as it shows saturated, green color in a primary, large crystal. This main crystal has an unusual four sided form, that you don't see in the ordinary variety of Adamite. There is a sharp contrast between the glassy green, copper rich adamites and the brown Limonite matix. The primary crystal is 1.8 x 1.3 cms. An unusual and hard to find specimen.
