Fluorite, Quartz from Nasik District, Maharashtra, India [db_pics/mdpics/MD-112909a.jpg]

I was shocked to see purple fluorite from India. Never seen it, in 20 years-plus of looking at Indian specimens. Recently over the last 4 years, we have seen for the first time (at least so I believed and everybody else I know), rounded botryoidal fluorite from India : red and yellow hemispheres from Mahodari in Nasik. Somehow, Charlie had bought and stahed a whole previous pocket of fluorites, and a novel color for India no less, and nobody knew. I BUY A LOT of Indian minerals and believe me, I would have bought ANY purple fluorite from India if i had seen ONE SINGLE specimen out of the tens of thousands of pieces I have been offered over the years. It simply wasn't to be had. I asked Charlie how the hell...and he just chuckled and said he "got good things from time to time an dput them away." Charlie had apparently bought this small pocket in the late 1980s , and it was all he had seen, as well. This is the largest specimen of the small group we found in his collection - nestled in with a large and extensive Indian Collection Suite which we will post later in the year. This piece is pristine , and it positively glows when backlit with the light shining through both the translucent fluorite and the thin quartz late on which it rests. This hemisphere measures 5 cm across. NOT a pale lavender, but a nice rich shade of purple! Rare and unusual, I would say... 11.9 x 6.5 x 2.7 cm


MD-112915 - Proustite, Quartz - - Archived
Schlema, Schlema-Hartenstein District, Erzgebirge, Saxony, Germany

Proustite, Quartz from Schlema, Schlema-Hartenstein District, Erzgebirge, Saxony, Germany [db_pics/mdpics/MD-112915a.jpg]

A SHARP crystal of wine-red proustite just perched right up atop a pedestal of quartz! NICE thumbnail or small mini! The sharply steepled termination is pristine and the crystal is only contacted on the back and the right side, away from the viewing display. 3.3 x 2.2 x 1.7 cm


MD-113273 - Quartz (Var: Amethyst) - - Archived
Turkana District, Rift Valley Province, Kenya

share specimen

CLICK HERE FOR LARGER IMAGE:
Quartz (Var: Amethyst) from Turkana District, Rift Valley Province, Kenya [db_pics/mdpics/MD-113273a.jpg]

31.5 x 8.1 x 8.1 cm. This monstrous sceptre quartz is simply unprecedented in Africa...even Brandberg doesn’t produce them as large and dramatic as this! It is an amazing piece, which is much more impressive in person as it is hard to convey the sheer size in pictures (12 INCHES!). There are all kinds of interesting inclusions inside, including hematite, amethyst and smoky zones, and lepidocrocite. This is by far the largest crystal we have so far. It is doubly-terminated, though the bottom termination is repaired (some damage is visible from the backside but from the front or side, honestly you’d never notice at all...it’s a pretty clean repair job).


MD-113277 - Quartz - - Archived
Grischun (Grisons; Graubünden), Switzerland

large cabinet, 22.7 x 7.5 x 2.6 cm.
share specimen

Quartz from Grischun (Grisons; Graubünden), Switzerland [db_pics/mdpics/MD-113277a.jpg]

22.7 x 7.5 x 2.6 cm. A DRAMATIC, LARGE CABINET, doubly terminated, tapering quartz crystal from Graubunden, Switzerland. This giant is very glassy and translucent. Super trivial contacting on one termination only! A complete, all-around floater! This is from the noted Wein collection.


MD-113302 - Galena, Quartz - - Archived
Neudorf, Harzgerode, Harz Mts, Saxony-Anhalt, Germany

Galena, Quartz from Neudorf, Harzgerode, Harz Mts, Saxony-Anhalt, Germany [db_pics/mdpics/MD-113302a.jpg]

4.7 x 3.8 x 2.2 cm. A lustrous, sharp, 1.3 cm, complex galena crystal nicely set on glassy quartz crystal matrix from Neudorf, Germany. This is CLASSIC, OLD-TIME material from a renowned location. This specimen is easily over 100 years old. Ex Joseph Rawlings and Seaman Museum Collections. Rawlings was born in 1826 and worked as engineer at the Cliff and Minnesota Mines. The Cliff closed in 1883!


MD-113369 - Apatite, Quartz - - Archived

6.0 x 5.1 x 3.2 cm. Lustrous, pastel-pink apatite balls richly cover quartz matrix on this very fine, CLASSIC, OLD-TIMER from Schlaggenwald, Erzgebirge, Czech Republic. Come with an old label in German.


MD-113378 - Quartz (Var: Chalcedony), Chrysocolla - - Archived
Ray Mine, Scott Mountain area, Mineral Creek District (Ray District), Dripping Spring Mts, Pinal Co., Arizona, USA

Quartz (Var: Chalcedony), Chrysocolla from Ray Mine, Scott Mountain area, Mineral Creek District (Ray District), Dripping Spring Mts, Pinal Co., Arizona, USA [db_pics/mdpics/MD-113378a.jpg]

2.5 x 2.5 x 2.2 cm. A GLORIOUS thumbnail of transparent chalcedony coating turquoise-blue chrysocolla stalactites from the famous Ray Mine of Arizona. This is about as good as it gets, with the twin spires dominating this beautiful piece. Ex. Sam Nasser collection.


MD-113438 - Spessartine, Quartz (Var: Smoky Quartz) - - Archived
Wushan Spessartine Mine, Tongbei, Yunxiao Co., Zhangzhou Prefecture, Fujian Province, China

miniature, 4.3 x 3.8 x 3.4 cm.

Spessartine, Quartz (Var: Smoky Quartz) from Wushan Spessartine Mine, Tongbei, Yunxiao Co., Zhangzhou Prefecture, Fujian Province, China [db_pics/mdpics/MD-113438a.jpg]

4.3 x 3.8 x 3.4 cm. These new Spessartines are some of the most attractive and highly displayable specimens to come out of China in the last few years. This particular piece features several lustrous, gemmy, bright orange trapezohedra with dodecahedral modifications associated with a few highly lustrous, gem quality Smoky Quartz crystals and light greenish color Muscovite crystals on Orthoclase. The color in these crystals is very attractive, and they are not at all dull or pitted. This material is becoming less and less available on the market, and keep in mind that there are only a few worldwide localities that produce this color of Spessartine in fine specimens. Bright orange Spessartine specimens are NOT easy to find these days from any locality.


MD-113441 - Stilbite, Apophyllite, Quartz - - Archived
Pune District (Poonah District), Maharashtra, India

large cabinet, 17.5 x 7.4 x 6.6 cm.
share specimen

Stilbite, Apophyllite, Quartz from Pune District (Poonah District), Maharashtra, India [db_pics/mdpics/MD-113441a.jpg]

17.5 x 7.4 x 6.6 cm. A large, glittering, amazing specimen from India, a real showstopper! It is a stalactite of quartz that has been completely covered with sparkly microcrystalline apophyllite - and on the apophyllite field have grown dozens of chisel-shaped, pearly stilbite crystals. It is complete all the way around, with a narrow area of contact on back where the stalactite apparently was conjoined with the wall of the vug or cave. (Ex.Ed David Collection).


MD-113444 - Calcite, Quartz - - Archived
Droujba (Drujba) Mine, Djurkovo Complex, Laki (Luki), Rhodope Mts, Plovdiv Oblast, Bulgaria

Calcite, Quartz from Droujba (Drujba) Mine, Djurkovo Complex, Laki (Luki), Rhodope Mts, Plovdiv Oblast, Bulgaria [db_pics/mdpics/MD-113444a.jpg]

7.1 x 4.4 x 4.2 cm. A beautifully-trimmed and balanced Eastern European calcite specimen, with two snowy calcite crystals with sharp faces centered on a matrix of translucent quartz crystals; the Rhodope Mountains have been producing wonderful calcites on and off for years now, in a great variety of forms and combinations with other minerals.


MD-113447 - Galena, Chalcopyrite, Quartz - - Archived
Yuzhna Petrovitza deposit, Borieva Mine, Madan ore field, Rhodope Mts, Smolyan Oblast, Bulgaria

Galena, Chalcopyrite, Quartz from Yuzhna Petrovitza deposit, Borieva Mine, Madan ore field, Rhodope Mts, Smolyan Oblast, Bulgaria [db_pics/mdpics/MD-113447a.jpg]

4.8 x 4.3 x 3.7 cm. Just a GREAT-looking galena from the prolific Madan district - these crystals are so sharp and well-formed, and have the best shiny-metallic luster. They are accented with some creamy calcite, and sit on a large chalcopyrite crystal, which creates a nice contrasting natural base for the galenas.


MD-113450 - Quartz - - Archived
Macaco mine, Conselheiro Pena, Doce valley, Minas Gerais, Southeast Region, Brazil

Quartz from Macaco mine, Conselheiro Pena, Doce valley, Minas Gerais, Southeast Region, Brazil [db_pics/mdpics/MD-113450a.jpg]

9.9 x 4.2 x 2.2 cm. Complete and terminated all around, a super-complex specimen of so-called "elestial" quartz, which have the appearance of aggregates of gemmy, beta-style smaller quartz crystals. The faces are glassy and flashy!


MD-113454 - Quartz (Var: Amethyst), Hematite - - Archived
Diamond Willow Mine, Pearl Station, Thunder Bay District, Ontario, Canada

small cabinet, 5.4 x 5.0 x 2.0 cm.
share specimen

Quartz (Var: Amethyst), Hematite from Diamond Willow Mine, Pearl Station, Thunder Bay District, Ontario, Canada [db_pics/mdpics/MD-113454a.jpg]

5.4 x 5.0 x 2.0 cm. From near the famous Thunder Bay locality which is renowned for these - a cluster of lustrous amethyst crystals accented by rusty-red inclusions of hematite.


MD-113486 - Boulangerite, Quartz - - Archived
Yaogangxian Mine, Yizhang Co., Chenzhou Prefecture, Hunan Province, China

Boulangerite, Quartz from Yaogangxian Mine, Yizhang Co., Chenzhou Prefecture, Hunan Province, China [db_pics/mdpics/MD-113486a.jpg]

5.8 x 5.3 x 3.8 cm. You mostly see boulangerite as merely a color tone inclusion inside calcites from Eastern Europe. In this Chinese specimen, it is represented by a rich carpet of fine needles at the base of gemmy quartz crystals.


MD-113496 - Quartz, Hedenbergite, Goethite - - Archived
San Antonio Mine (San Antonio el Grande Mine), East Camp, Santa Eulalia District, Mun. de Aquiles Serdán, Chihuahua, Mexico

cabinet, 11.0 x 9.1 x 4.2 cm.

Quartz, Hedenbergite, Goethite from San Antonio Mine (San Antonio el Grande Mine), East Camp, Santa Eulalia District, Mun. de Aquiles Serdán, Chihuahua, Mexico [db_pics/mdpics/MD-113496a.jpg]

11.0 x 9.1 x 4.2 cm. This plate of glassy, flashy quartz from the Glover collection is distinctive due to the rich inclusions of hedenbergite and goethite, which give the crystals a rich mossy color. Fine quartz specimens are unusual from the San Antonio Mine, and actually, except for the amethyst variety, are not all that common from Mexico in general.
