Plumbogummite replacing Pyromorphite
stock #19.1-336
Daoping Lead-Zinc Mine, Yangshao
Guangxi Autonomous Region, China
7.5 x 5.1 x 2.7 CM (cabinet)
price: $950


An elegant specimen with flowerlike crystal sprays on a powder blue matrix. The crystals are in several stages of pseudomorphing from Pyromorphite to Plumbogummite. These are in excellent condition, complete and undamaged which is very rare in these specimens. Many of the free standing crystals are light blue on one side and yellow-green on the opposite side. These amazing Plumbogumites from China were big mineral news when these were first found, they have been recognized as the worlds best.
Plumbogummite and Mimetite, Pyromorphite
stock #18-AX-14B-130
Dry Gill Mine, Caldbeck Fells
Cumberland, Cumbria, England
4.4 x 2.2 x 2.2 CM (miniature)
price: $400


A very old or "vintage" specimen, previous label notes it to have been collected 1830-40 era. The labels call the associated crystals Mimetite although it looks to me like the larger greener ones are Pyromorphite with some yellow Mimetites as a second generation. This specimen is pictured on Mindat and it is labeled Pyromorphite there. Ex Ben Shumer collection, this is a small but pretty and colorful miniature. Under good magnification it is quite incredible, delicate and the blue Plumbo balls sparkle. Quite three dimensional, a nice classic specimen from this famed locale. Before the great Chinese Plumbogummites were found recently. English pieces (from Roughton Gill and Dry Gill) were the worlds best, prized in top collections all over the world. Despite the beauty of new Chinese pieces these old English specimens are still very special and quite different too. This mine was last worked in 1869, and was one of the worlds most important mineral localities.
Quartz Scepters with Sphalerite, Calcite etc
stock #18-AX-1-378
Verhniy mine, Dalngorsk
Primorsky Kray, Far Eastern Region, Russia
4.8 x 4.2 x 3 CM (miniature)
price: $285


A well proportioned Scepter of Quartz that has a milky phantom in the head sits on a mix of smaller crystals. Overall very esthetic and looks great from all sides, this is in outstanding condition. Vintage 1992-3 from the Verkhnil (Verhniy) Mine at Dalngorsk, this miniature has nice display impact. Ex William Hladysz collection.
Lithiophorite
stock #19.1-373
Olesna, Horovice, Beroun District
Central Bohemia Region, Czech Republic
7.1 x 6 x 4.4 CM (cabinet)
price: $40


A black ugly, nearly pure, globular Lithiophorite that is a very good example of the specie and the locality. From an old Czech collection, this Manganese Oxide mineral (with Aluminum and Lithium) is never a "pretty" mineral, but it is uncommon and this a rich specimen.
SOLD Rutile sixling twins, coated with Romanechite
stock #SOLD 16.1-331
Novo Horizonte
Bahia, Brazil
4.3 x 4.2 x 3.2 CM (miniature)
price: $0


A unique and rather bizarre specimen of Sixling twinned Rutile (epitaxial on Hematite" that is coated on almost every surface with a secondary growth of Botryoidal Romanechite. The form is very well defined and sharp, the twins are repeated and stacked in a line showing repeat orientation. A wonderful textbook perfect twin specimen that has the added oddity of being coated with what looks to the naked eye like a soot but with magnification is all botryoidal encrustations. In great shape, on the backside a small area of the Rutile is exposed and the hairs are clearly seen in bright golden color. We have visited Bahia ,and handled a lot of Rutile from there and elsewhere, but this is the only specimen I have ever seen like this. It was suggested that this be cleaned and made to look bright and fresh as is typical of Rutile. I prefer it like this as a very different if dark specimen that is unlike any other.
Dolomite with Quartz
stock #19.1-372
Traversella, Chiusella Valley, Canavese DistrictMetropolitan city of Tur
Piedmont, Italy
5.3 x 3.5 x 2.4 CM (cabinet)
price: $120


A cute and unusual Dolomite that is in translucent blocky rhombs nestled with clear Quartz crystals. A vintage specimen with old labels ex Pallanza collection. Very good luster and condition, Dolomites from this area of the Piedmont are known in many habits and styles, this one look much more like a French Alpine specimen but is really from the Piedmont.
SOLD Aurichalcite, Hemimorphite
stock #SOLD 19.1-371
Gorno, Riso Valley, Bergamo Province
Lombardy, Italy
6.6 x 4.2 x 2.8 CM (cabinet)
price: $0


An old Italian specimen, a brightly colored Aurichalcite deposited on top of a light blue Hemimorphite. The coverage on this matrix is quite dense and rich, unlike the more typical isolated micro tufts. Several old labels (Sisi, Sperulunga collections) are included. The backside is a complex mass of Hemimorphite in wormlike structures with a few Aurichalcites in small vugs.
Adamite - Manganoan on yellow/green
stock #19.1-262
Mina Ojuela, Mapimi
Durango, Mexico
2.8 x 2.6 x 1.5 CM (thumbnail)
price: $1150


Killer thumbnail of sharp Manganoan Adamite crystals clustered like a crown on a base of lemon yellow to green Adamites. The Manganoan crystals have light purple and reddish-pink zones with glassy luster, transparent in areas. . Ex collections of Willard Perkins (inventor of the Perky box) and Kay Robertson. In excellent condition, the display side is perfect and competition grade, the backside is contacted where it grew on host rock. With all the fine Adamites to come out of Ojuela it can be hard to find one that is exceptional or stands out. This one is top level with a unique form.
