SOLD Pectolite
stock #SOLD 20.1-882
Jeffrey Mine, Asbestos
Quebec, Canada
3 x 2.2 x 1 CM (thumbnail)
price: $0
new year 2021

Very esthetic 360 degree thumbnail specimen of perfect radiating crystals of Pectolite and no matrix. These crystals are transparent and in person the luster is bright and glassy. Pectolite is not often a pretty mineral and is most often seen as needle like crystals in radiating balls. This blocky prismatic style is quite different and one of the classic fine minerals from the Jeffrey Mine. I have not seen another Pectolite thumbnail this well-composed. Also vividly fluorescent with an orange response. Choice.

Grossular - gemmy crystals
stock #AX-16-570
Jeffrey Mine, Asbestos
Quebec, Canada
2.2 x 2 x .6 CM (thumbnail)
price: $175
new year 2021

Thumbnail specimen of fine transparent Garnet. These are well-defined, isolated and brilliantly lustrous. The Garnets are perched on a very thin plate of matrix, all show glassy striations on the larger faces. From the great Jeffrey Mine, this thumbnail is a fine but scaled-down version of larger specimens that can cost a fortune when available.

Quartz - optically clear
stock #20.1-881
Peñas Blancas, San Pablo de Borbur
Boyacá, Colombia
5.3 x 3.7 x 2.2 CM (small cabinet/ large miniature)
price: $380
new year 2021

Some of the world's clearest and most perfect Quartz has come from the finds in the ridge above the Peñas Blancas Emerald Mines in Boyacá, Colombia. This is an incredibly clean highly lustrous example, one of a small carefully selected suite we obtained at the mine. The luster is brilliant and almost impossible to see in a photograph. This zone has recently produced a lot of good to fine Quartz but very close exam finds that there are very few truly perfect examples, nearly all have at least some chips or rough spots on terminations. This is a remarkably limpid and flawless piece that can act as a prism to make rainbows. Nothing like the average material from here, this is textbook perfect. As is sometimes seen at this locale this piece has some extra faces in corners adding some nice modifications.

Demantoid (Andradite) - vintage classic garnet
stock #20.1-616
Val Malenco, Sondrio Province
Lombardy, Italy
6.3 x 5.2 x 2.7 CM (cabinet)
price: $370
new year 2021

A chain of linked line of apple-green Garnets on a Rodingite/Serpentine matrix. The specimen is from the old locality of Val Malenco and was collected prior to 1905. The form and color of these Andradites are classic and immediately recognizable. In very good condition as seen, just one very small chip is noted, the crystals reach up to 1.3 CM in a 4.7 CM line. The luster is waxy and the crystals are all transparent to translucent. In person the color is close to a good deep Peridot hue.

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.
