Quartz (Var: Rose Quartz) from Alto da Pitorra, Laranjeiras, Galiléia, Doce valley, Minas Gerais, Southeast Region, Brazil [db_pics/mdpics/MD-51115a.jpg]

White crystals of albite form the contrasting matrix for this specimen of rose quartz. The rich pink color of rose quartz in a floral pattern has crystals that reach 2 .0 cm in length. 5 x 4.9 x 3.1 cm

Quartz (Var: Rose Quartz) from Alto da Pitorra, Laranjeiras, Galiléia, Doce valley, Minas Gerais, Southeast Region, Brazil [db_pics/mdpics/MD-51118a.jpg]

This is another pink specimen of richly colored, lustrous, rose quartz that looks very much like a flower. What makes it extra special is not just the intensity and color, though: rather, the largest crystal measures almost 4 cm in length. The color intensity is unreal. This piece also has crystals that are huge for a rose quartz, where for some reason large crystals are rarely formed. 8 x 4.8 x 4.4 cm.


MD-51153 - Calcite, Quartz (Var: Amethyst), Pyrite - - Archived

Calcite, Quartz (Var: Amethyst), Pyrite from Rio Grande do Sul, South Region, Brazil [db_pics/mdpics/MD-51153a.jpg]

A unique specimen, like none I have seen before from this region. It features a superb, gemmy, transparent, twinned calcite measuring 3 cm across, perched with smaller calcites cascading down the termination of a deep purple amehtyst point. It is amazing such a thing survived being found and cut out of the enclosing amethyst cathedral in which it surely grew. The lustre, and contrasting colors, the complex form of the calcite...all combine to make this a really stunning and unique piece. 9.6 x 4.8 x 5.5 cm


MD-51155 - Brazilianite, Quartz (Var: Smoky Quartz) - - Archived

Brazilianite, Quartz (Var: Smoky Quartz) from Córrego Frio mine, Linópolis, Divino das Laranjeiras, Doce valley, Minas Gerais, Southeast Region, Brazil [db_pics/mdpics/MD-51155a.jpg]

This is the only such specimen I have ever seen, of brazilianite from the original 1940s finds associated with smoky quartz. The contrast is striking! The brazilianite is exceptionally lustrous and gemmy as you would want for a specimen from the older finds, still not beaten by anything found later on at several other locales in Brazil. This is a unique, competition-quality miniature from an old collection in Europe, from whence I got it in trade. 6.3 x 4.1 x 4 cm

Wavellite, Quartz from Llallagua, Rafael Bustillo Province, Potosí Department, Bolivia [db_pics/mdpics/MD-51161a.jpg]

A gorgeous 1.5 cm spherical crystal ball of wavellite perched on quartz! Classi cmaterial, but rare in such aesthetic quality. Also the lustre of the wavellite is unusually high. 5.7 x 3.1 x 2.8 cm


MD-51167 - Tourmaline, Quartz - - Archived

Tourmaline, Quartz from Mogok, Sagaing District, Mandalay Division, Burma (Myanmar) [db_pics/mdpics/MD-51167a.jpg]

An outstanding, gemmy, brilliantly lustrous tourmaline nestled within and against a quartz! This aesthetic piece is really special, because they just do not often come like this, from Mogok. Usually you get matte-finish or opaque crystals....very rarely lustrous and gemmy as of Brazilian calibre! The tourmaline and its termination are complete. 3 x 2.8 x 2.2 cm


MD-51173 - Quartz (Var: Prase), Hedenbergite - - Archived
Serifos Island (Seriphos), Cyclade Islands (Cyclades; Kikladhes; Nomos Kikladhon), Kykládes Prefecture, Aegean Islands (Aiyaíon) Department, Greece

This is a damned good example of the classic Greek "prase" anyhow, with dramatic crystals to 5.5 cm leaping up from the matrix. Prasem was the name given to these classic quartzes, colored green by rich inclusion of hedenbergite. But beyond the obvious, it has really neat crystallized hematite rosettes in association, which I have never seen before on these! A coating of soft, fibrous actinolite overlays the "valley" running down the middle of the specimen in which teh hematite rosettes lay as well. I like that the actinolite remains, as usually it is completely blown away from the specimen, leaving them "naked". 10.8 x 8.8 x 6.5 cm


MD-51174 - Quartz, Anatase, Clay - - Archived

Quartz, Anatase, Clay from Curvelo, Minas Gerais, Southeast Region, Brazil [db_pics/mdpics/MD-51174a.jpg]

This piece has to be seen in person to be believed. It is an absolutely mesmerizing floater crystal with INCREDIBLE glassy lustre that looks like it was just windexed and polished (but hasnt been!), and fascinating inclusions. It has yellow color due to an odd claylike material included within, overlaying internal matrix or primary generation of quartz. On top of that layer, rest SHARP anatase crystals, some of them also twinned, to 1 cm in length. It is like looking at them down through a swimming pool, of such clarity that you wonder if it is glass or water...LITERALLY, this is a mesmerizing piece and one of the most interesting included quartzes I have handled, if not the most expensive by a long shot. 8.5 x 7.8 x 3.8 cm


MD-51178 - Quartz, Manganbabingtonite - - Archived

Quartz, Manganbabingtonite from Fengjiashan Mine (Daye Copper mine), Edong Mining District, Daye Co., Huangshi Prefecture, Hubei Province, China [db_pics/mdpics/MD-51178a.jpg]

This is a unique specimen, like none I have seen so far from China, as it features a Japan Law twin quartz included with a scattering of microcrysatllized babingtonite! The resulting complexity of the crystal is really interesting, and stands out from every other jap twin I have seen. I love it! The major crystal is 4 cm across. There are also half a dozen smaller twins present, though not as richly ncluded or as large. 10.5 x 6 x 4 cm


MD-51179 - Quartz (Var: Smoky Quartz), Microcline (Var: Amazonite) - - Archived

Quartz (Var: Smoky Quartz), Microcline (Var: Amazonite) from Crystal Peak area, Park and Teller Cos., Colorado, USA [db_pics/mdpics/MD-51179a.jpg]

This is a classic combination, in rare aesthetic and dramatic form and balance! Ogften, you have too much smoky or too much amazonite, but this is such a perfect mix of the two, I couldn't believe it was unrepaired and unfaked. The smoky is GEMMY and sharp, and completely terminated and freestanding 360 degrees around. The amazonites have the best color you could have asked for in pre-Tree Root Pocket material from the region, and the contrast between the sharp smoky is stark and dramatic. It comes from the noted collection of Dr. Dick Webster, one of the founders of plastic surgery and a major mineral collector several decades ago. This collection just surfaced through his children, to the market, with a friend of mine. Generally, all are good and all are classics...he had damned good taste! But this piece, while not nearly the most expensive in the collection, was one of my alltime favorites for its unique qualities. This is a superb example worthy of any collection. 8.2 x 7 x 6.2 cm

Epidote, Quartz from Hongquizhen Quarry, Meigu Co., Liangshan Autonomous Prefecture, Sichuan Province, China [db_pics/mdpics/MD-51180a.jpg]

This specimen hosts the largest and best epidote crystals I have yet seen from this recently productive locale in China, with sharp curved crystals measuring a whopping 2.5 cm, standing up against matrix of a host quartz crystal. I have not seen other epidotes from here of even half this size, commonly. In person, the epidote is more glassy and 3-dimensional, and has a very dark green color. These were initially mislabelled as pumpellyite when they first came out some 3 years ago, but they have been shown since to be epidote - if unusual in forma nd quality. This is MUCH BETTER IN PERSON! 6.4 x 4.9 x 2.3 cm


MD-51193 - Quartz (Var: Rose Quartz), Quartz - - Archived

Topaz, Quartz, Albite from Gaoligong Mts (Gaoligong Shan), Nujiang Autonomous Prefecture, Yunnan Province, China [db_pics/mdpics/MD-51195a.jpg]

An amazing specimen from a very small pocket recently found, that has the best color yet seen in Chinese topaz. The color in fact rivals Pakistani material, finally! This attractive matrix piece boasts crystals to 2.25 x 2 x 2 cm in size, with brilliant lustre and deep champagne color. As the crystals go larger in size, they shed some of the color intensity but get sharper and more gemmy, even (those to come in later updates). This is by far the best lot I have seen yet, although the mine has trickled material out for the last 5 years or so, sporadically. 12.9 x 8.7 x 4.6 cm

Quartz (Var: Amethyst) from Veracruz, Mexico [db_pics/mdpics/MD-51198a.jpg]

These brilliantly glassy, lustrous crystals were found early last year in a new find at this old locality. The differ from previous finds in the high lustre and unusually even lavender color, whereas most amethysts from this place show either uniform deeper purple hue or a gradient from purple to clear. This is a pristine, very attractive cluster and was one of the best of the lot 8.5 x 6.2 x 4.3 cm

This is a pristine, very attractive cluster and was one of the best of the lot. It has among the largest crystals of the find, as well. There is a contact on the left side, that is not damage but still an asymmetry that needs to be mentioned 8.4 x 4.6 x 2.5 cm
