Wulfenite on Gibbsite (rare association)
stock #AX-15-053
Baoshan Prefecture
Yunnan Province, China
7 x 5.5 x 3.6 CM (cabinet)
price: $650
Winter 2016-17

An attractive, delicate and rich color Gibbsite is host to dozens of sharp Wulfenite crystals. This is the only specimen of this rare association that I have ever seen. Ex. Shields Flynn collection which he obtained from Bert Ottens. In perfect condition, this would be a really fine Gibbsite even without the Wulfenites. Displays well from many angles. Choice!

Serandite and Aegirine (rare form)
stock #A7-257-(439A)
Mont Saint-Hilaire, Monteregie
Quebec, Canada
6.9 x 2.6 x 2.4 CM (cabinet)
price: $880
Winter 2016-17

A delicate sculptural Serandite specimen with a delicate salmon color. Ex Larry White collection, this is composed of the uncommon blade-like habit crystals inter-grown in parallel arrangement. Collected in 1980 by Ernie Schlicter, this is unlike most Serandite, the flat crystal form is very rare, and with the mine closed there are no more to be found. The spike-like crystal of Aegirine is a nice accent.

Sperrylite crystals with Native Gold on Chalcopyrite (type locale)
stock #AX-16-433
Vermillion Mine, Denison, Sudbury District
Ontario, Canada
4.3 x 3.2 x 2.1 CM (miniature)
price: $1550
Winter 2016-17

Sperrylite is a scarce Platinum Arsenide that has only been found in good crystals at just 3 locations worldwide. This is an especially nice association piece with both Platinum and Gold on the same specimen. This is an older example from the Vermillion Mine (the type locale) and ranks as one of the very best examples I have seen from this deposit. A series of Gold veins and bleb run through the matrix mostly on the back side. Recent finds at Broken Hammer and earlier finds in Siberia have produced some larger crystals that are are best for the mineral but are also very expensive. This specimen is not of the top caliber but still very good and not priced in the 5 or 6 figures! A sharp, very bright lustrous metallic cube and some complex modified octahedra are nestled on the contrasting Chalcopyrite. Mostly intact and quite fine for the specie and locale.

Pectolite - prismatic crystals in radiating clusters
stock #AX-24-511
Jeffrey Mine, Asbestos (now Val-des-Sources, Estrie,
Quebec, Canada
8 x 5.7 x 3.2 CM (cabinet)
price: $850
Winter 2016-17

Pectolite is not usually an attractive mineral and good prismatic crystals are quite rare. This is a strong exception to that rule. More than 25 years ago a series of pockets at the Jeffrey Mine produced some of the most perfect and esthetic specimens of this usually drab mineral. Several crystals are transparent and all others are translucent. A perfect undamaged floater there is no matrix or point of attachment. Outstanding for the specie, choice, very large and rarely available now.

Diopside - gemmy crystals on matrix
stock #AX- 35-524
Calvin Mitchell Prospect, Dekalb, St Lawrence County
New York, United States
4.3 x 4 x 2.6 CM (miniature)
price: $700
Winter 2016-17

Fine and sharp gem clear Diopside crystals on a Diopside matrix in excellent condition. From the famed Dekalb classic location made famous in the 1800s, The largest crystal is 2.3 CM long and has fine transparency and a nice yellow-green color. This was collected by and in the collection of S. Alverson in the last good find over 4 decades ago. Since that pocket there have been no more with this clarity and glassy luster. Outstanding for the location and an esthetic piece as well!

Smithsonite - gemmy scalenohedral crystals
stock #14.1-058
Tsumeb
Otjikoto Region, Namibia
7 x 6 x 2.9 CM (cabinet)
price: $1050
Winter 2016-17

Yellow-hued crystals of transparent Smithsonite up to 2.5 cm long are sticking out in all directions on this complex yet esthetic piece. In outstanding condition overall, there is one crystal with a broken termination that will be hidden on most logical display angles. All of the other crystals are quite perfect. Without analysis I am not sure if this should be called Cadmian Smithsonite as many yellow examples are labelled. Choice and attractive.

Elbaite - gem grade crystal
stock #15.1-422
Resplendor Mine - Doce Valley
Minas Gerais, Brazil
4.9 x .8 x .4 CM (miniature)
price: $580
Winter 2016-17

Sharp, pure gem clear grade with fine green to blue green color. The photos have a very slight backlighting, with a stronger backlight this crystal glows intensely and shows some blue zones as well. In fine condition as seen with top notch glass-like luster internally flawless and super clear. Older material from the famed Resplendor Mine, there has not been any like this available for some time.

Smithsonite on Galena
stock #16.1-562
Tsumeb
Otjikoto Region, Namibia
4 x 3.3 x 2.9 CM (miniature)
price: $900
Winter 2016-17

Outstanding esthetics, in fine condition a very choice Tsumeb piece. The matrix is the classic type of Tsumeb Galena with small areas of Cerussite best seen with magnification. The Smithsonites contrast nicely with the matrix. Colorless to very pale pink hues on crystals reaching 1.7 cm with fine transparency as well. Displays with great impact despite the small size!
