SOLD Krennerite - rare Gold Telluride
stock #SOLD 20.1-699
Kalgoorlie-Boulder Shire
Western Australia, Australia
3.4 x 1.7 x 1.5 CM (small miniature/ large thumbnail (toenail))
price: $0
new year 2021

Small crystals in aligned clusters with some larger masses of Krennerite in several spots on a greenish matrix, from Western Australia. Krennerite is a quite rare Gold and Silver Telluride that is only known in decent specimens from a small number of localities, most all being old and no longer productive. This is a very good reference grade specimen best appreciated with Magnification. The famed one time find of larger crystals many years ago in Fiji stands as the greatest of all time. This specimen is not in that class, but it is also not priced in the six figures either! 12.5 grams weight for this small specimen indicates a rather rich Gold content. Although this is not a "display grade" specimen it is a a good reference piece for collectors of Gold and Gold Tellurides.

Carnelian - red Quartz nodule
stock #1047-JM-1645
Fassa, Val de Fassa, Trentino -Alto Adige
South Tyrol, Italy
4.6 x 4.3 x 2.8 CM (miniature)
price: $360
new year 2021

A half nodule of bright red Quartz (crypto-crystaline variety Carnelian) from Fassa which is now in Italy (since 1919) but at the time this was found was in Austria. From the Phil Scalisi collection and also was in the John Marshall collection Translucent to transparent, an excellent example of an old European Carnelian gem that is just not often seen for sale.

Azurite on Malachite
stock #AX-3-045
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
3.7 x 2.6 x 1.6 CM (small miniature/ large thumbnail (toenail))
price: $1350
new year 2021

From the great finds at Milpillas, this is a very fine small miniature in perfect condition with excellent esthetics. The Azurite crystals stand up from the contrasting green Malachite which covers a thin shard of matrix. These are translucent on the edges with a brilliant blue. A few tiny spots on the Azurites show Malachite alterations and the overall luster is very bright. With a close exam or under magnification the crystals are seen as compound prisms made from aligned crystals in an almost rosette structure. This piece is more impressive in person, and has a lot of display impact for its size. When Milpillas was active it produced lots of good Azurite and also a few really great pieces. Finding an above average specimen with rich color contrast in perfect condition (and at a fair price) was never easy. This is that sort of piece.

Quartz - classic locale
stock #15.1-732
Vizille, Grenoble, Isere
Auvergne-Rhône-Alpes, France
9.4 x 7.3 x 7.7 CM (cabinet)
price: $230
new year 2021

The Quartz localities clustered near Grenoble in Isere, France were sources of some of the most classic and special Quartz specimens in the world. This piece shows well the forms of the slender clear Quartz prisms perched on an altered Siderite "Limonite" matrix. In exceptional undamaged condition, this is from the Dr. Warren Johansson collection, he purchased this in 1984. A nice sized cabinet specimen that shows well the clarity and luster that these are famed for at a reasonable cost for one of these European classics.

Quartz included by Epidote
stock #20.1-880
Cisneros, Mun. de Buenaventura
Valle del Cauca, Colombia
4.1 x 3.3 x 2.1 (miniature)
price: $150
new year 2021

A light greenish Quartz that is slightly milky is surrounded by and included with slender Epidote crystals. From a remote locality in the Gold mining areas of the Cauca Valley of Colombia, these greenish Quartz and Epidote have trickled out for several years, never many pieces and usually badly damaged. This is from a small lot we obtained in Colombia in 2018 and is far better than usual. The front or display side offers a large window into the Quartz where the Epidote are like a forest or garden scene. The backside has a clean geometric contact and the condition is overall very good, strong magnification does show some very tiny bruises that are not visible by naked eye, for one of these remarkable crystals this as close to perfect as we have seen. A very different and attractive small Quartz.

Dolomite cast with Calcite
stock #16.1-308
Otjikoto Region, Namibia
4.3 x 3.4 x 2.2 CM (miniature)
price: $120
new year 2021

One of the many odd but amazing things found over the years in Tsumeb were hollow Dolomite casts. These are replacements or encrustations of earlier minerals which have since disappeared. Sometimes the casts have then been overgrown with other minerals as well. The forms are quite diverse and entire collections have been made of the many shapes, colors and associations. This miniature cast is a pale green color and is overgrown with gem clear, colorless Calcite rhombs. The walls are typically thin and the whole specimen is a delicate hollow structure. Looks great from any angle, an attractive example of a mineral oddity.

stock #14.1-380
Minas Gerais, Brazil
4.6 x 3.5 x 1.4 CM (miniature)
price: $300
new year 2021

A pair of fine, sharp and lustrous crystals of Epidote from Capelinha in Brazil. Most of the Epidote we see from Brazil is a more fibrous habit, this prismatic specimen is the best formed I have ever seen. Textbook perfect crystals with well-defined terminations and on the backside a few clusters of small Quartz crystals. Overall in excellent condition as seen, the faces are either well-striated or perfectly flat, mirror-like and brilliantly lustrous. The sharpness and quality of this could easily be confused with a fine Alaskan Epidote.

SOLD Fluorite on Quartz
stock #SOLD AX-14-346
Orange River, Namakwa
Northern Cape Province, South Africa
3 x 2.8 x 2 CM (thumbnail)
price: $0
new year 2021

A super esthetic thumbnail from the Orange River area on the border of Namibia and South Africa. Orange River Quartz is well-known for the orange to red coloring of the crystals caused by Hematite inclusions. This piece has a light red zoning on transparent Quartz crystals that are the hosts for small zoned cubes of Fluorite. The Fluorites are very sharp, deep purple in the core with transparent zoning outside including a light yellow edge area. In fine condition overall, there is some very tiny chipping (under 0.2 mm) found with magnification, not visible to my unaided eye. This area has unusual mineralization which is unlike any other area I know of, this piece from a small unique find in 2017. This is a choice thumbnail from anyplace with nice color contrast.
