Olesna, Horovice, Beroun District
Central Bohemia Region,
7.1 x 6 x 4.4 CM (cabinet)
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.
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
Traversella, Chiusella Valley, Canavese DistrictMetropolitan city of Tur
5.3 x 3.5 x 2.4 CM (cabinet)
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.
Gorno, Riso Valley, Bergamo Province
6.6 x 4.2 x 2.8 CM (cabinet)
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.
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.
Wulfenite with Mimetite
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
1.7 x .9 x .8 CM (thumbnail)
Small but incredibly esthetic, a perfect window pane Wulfenite with a single bright red Mimetite ball. From the last work at the Rowley Mine which is now closed for safety reasons, this is a classic association. Very few of these were in such perfect condition. The color, form and condition of this are top quality, despite the small size this has a big visual impact. In person the color and luster are more vibrant than the photos show. This specimen is understandably delicate but is still shippable.
Diopside -single crystal
Orford Nickel Mine, Brompton Lake, Sherbrooke
5 x 1.6 x .8 CM (miniature)
Exceptional, perfect, partly gemmy and with glassy luster this is a great Orford Diopside. There were larger crystals found years ago but few were so well defined. This has the desirable honey yellow color and looks better in person. A modern classic with top quality, perfectly undamaged and looks fine from every angle.
SOLD Kyanite on Quartz
stock #SOLD 19.1-370
Barra do Salinas Mining District, Coronel Murta
7.8 x 3.7 x 2.5 CM (cabinet)
Kyanite crystals with Inky blue color with fine luster. Both crystals on the Quartz matrix are doubly terminated, in great condition with no damage. The larger crystal is a cluster of individual blades that start as a single prism and diverge to many separate sheaves all of which are terminated. Translucent and in a few spots transparent, this is a choice specimen of rich blue color. Kyanite is not a rare mineral but good free standing esthetic crystals are quite scarce.
