Quartz on Quartz replacing Calcite
stock #17.1-123
Langyang Mine
Fujian Province, China
9.6 x 7.2 x 5.3 CM (cabinet)
price: $360
new year 2021

A very attractive, bright sparkling Quartz specimen with an unusual form that looks like snowy mountain peaks. The core of this is a cluster of scalenohedral Calcites some partly replaced by Quartz and then overgrown by a new generation of clear slender Quartz needles much like cactus spines. The core Calcite is fluorescent (red and orange) and it shines through the exterior Quartz. The specimen overall is in fine, undamaged condition only broken on the underside where this was removed. This is from a small find about 5 years ago I have not seen anything quite like this since.

Mimetite (botryoidal yellow)
stock #6.2-936
San Pedro Corralitos, Municipio de Casas Grandes
Chihuahua, Mexico
6.7 x 5.7 CM (cabinet)
price: $575
new year 2021

From the earliest finds of several years ago this is a classic San Pedro Corralitos Mimetite. More recent finds never reached the quality of that original discovery. The very best have a wet-look luster, super bright color and very high price tags when available. They are world class. This piece is really good (far better than many) and has excellent three dimensionality, but does not quite reach the color and luster that would add a zero to the price. An excellent value for a very pretty Mimetite. The form is classic and displays well only a few very minor contacts are noted.

Calcite
stock #AX-19-212
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Russia
6.4 x 4 x 3.2 CM (cabinet)
price: $180
new year 2021

Thin undamaged hexagonal Calcites are clustered together without matrix. The crystals are all lightly frosted on the wide faces and are transparent to translucent. The arrangement of the crystals is quite esthetic and displays very well from almost any angle. An older Dal'negorsk specimen ex. Greg Kirby collection. The largest crystal is 4.3 cm wide and just 3mm thick with smooth, beveled side faces.

Wulfenite
stock #18-AX-504
Red Cloud Mine, Silver District, Trigo Mts, La Paz County
Arizona, United States
2.8 x 2.6 x 1.3 CM (thumbnail)
price: $300
new year 2021

A cute thumbnail with a choice, undamaged Wulfenite crystal nicely perched on matrix. Good color, great form and bright glassy luster this comes from the attempt a few years ago to rework some areas of this legendary mine. It is not so well-known that nearly all the Wulfenite from the Red Cloud is twinned, though much of it is hard to see by naked eye. This small crystal (1.1 CM) does show this rather well when examined closely. Nice esthetic example from this classic locale and in remarkably fine condition.

Libethenite - unusual rosette habit from type locality
stock #15.1-715
Lubietova, Slovenske Rudohorie Mts,
Banska Bystrica Region, Slovakia
6 x 4.8 x 3.6 CM (cabinet)
price: $350
new year 2021

An excellent very old Libethenite from the type locality with well-formed rosette structures. This habit is quite rare from Lubietova (originally Libethen) and these are sizable up to 5 mm which is large for any locale. From the collection of Dr Warren Johannson, his label notes he obtained it in a trade with Amherst College in 1982. The rosettes are in very good condition having been protected in a vug.

Vesuvianite
stock #AX-32-091
Jeffrey Mine, Asbestos
Quebec, Canada
2.4 x 1.3 x 1.2 CM (thumbnail)
price: $390
new year 2021

Bright, apple-green Vesuvianite crystal that is doubly terminated and has glassy lustrous faces. The crystal is complete all around and undamaged, fully translucent with some spots of transparency. There are a few small sidecar crystals that have some spots that are contacted and recrystallized on those edges, this is not seen without magnification. One termination is a deeper more emerald green color than the other. Overall a choice Vesuvianite from the famed Jeffrey Quarry, the only place on earth that ever produced Vesuvianite of this vivid color.

Apatite (Fluorapatite) on Calcite
stock #AX-10-663
Otter Lake, Pontiac County
Quebec, Canada
8.8 x 6.3 x 5 CM (cabinet)
price: $220
new year 2021

Doubly terminated, lustrous Apatite crystals set in a pink Calcite matrix. The Apatites are a mix of green to red-brown colors and have the typical slightly rounded edges noted from the Canadian Skarn deposits in this region. The matrix is sawn on the backside which is not visible on display. The smaller crystals have chipping but the largest (6.5 CM) is pristine. These Apatites are slightly transparent and fully translucent.

Sphalerite - USA tristate classic
stock #AX-35-135
Pelican Mine, Joplin Field, Jasper County
Missouri, United States
5.6 x 4.3 x 3.2 CM (cabinet)
price: $180
new year 2021

Textbook perfect, sharp Sphalerite crystal perched on Dolomite with a small bit of Chalcopyrite. The main Sphalerite crystal is complete all around, perfectly undamaged and has the silky luster that is typical from this locale. Through the 1960's, Tri-state specimens were very common even as the mines closed. These are no longer common and are unlike any other Sphalerites from other locales.
