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.

Plancheite
stock #20.1-823
Mindingi Mine, Kambove District
Haut- Katanga, Democratic Republic of Congo (Zaire)
7.3 x 5.2 x 4.1 CM (cabinet)
price: $290
new year 2021

A sizable mass of radiating fibrous crystals of Plancheite on matrix. The Plancheite specimens from the Congo are remarkably rich, considered by many the worlds best come from the Katanga region. This specimen is from an old find at the less well-known Mindingi Mine in Kambove. It is similar to other good specimens from the region and has the silky to chatoyant luster that is distinctive for the specie. Most often Plancheite is seen as an associate mineral, being the matrix for other Copper species, but it can be a very attractive specie in its own right. This looks especially impressive under magnification.

Vesuvianite - green tips with pink core
stock #AX-32-094
Jeffrey Mine, Asbestos
Quebec, Canada
2.6 x 1.9 x 1.3 CM (thumbnail)
price: $400
new year 2021

Fine glassy thumbnail with two main crystals that both have green terminations and light pink to violet bodies. The whole piece is translucent and when backlit glows a bright green to yellow with little of the pink showing. This sort of pastel Vesuvianite from Jeffrey is unique in the mineral world. There were several finds of this style there with the elongated blocky habit and pyramidal termination, but those were years ago and there will never be more. Already specimens of average quality are getting expensive and top pieces are nearly priceless. In very good condition, broken only from the base and back edge the terminations are perfect with no damage.

Copper - branching crystals on matrix
stock #20.1-824
Cliff Mine, Pheonix, Keweenaw County
Michigan, United States
6.2 x 3.6x 2.5 CM (cabinet)
price: $80
new year 2021

A tree of crudely crystallized Copper 3.5 CM tall branches from this blocky matrix. A few small chunks of colorless Calcite are on some branches as well, adding some contrast. The Copper branches are locked in the matrix along a line of small holes and are able to be moved several degrees but are still firmly held. The movement of the copper on the matrix is an oddity and not at all common.

Strontian Apatite (Fluorstrophite)
stock #20.1-753
Karnasurt Mountain, Lovozersky District
Murmansk Oblast, Russia
3.5 x 2.8 x 2.1 CM (miniature)
price: $420
new year 2021

Glassy stacked hexagonal crystals of the rare Strontium Apatite variety Fluorstrophite. These are fully translucent to slightly transparent on thin edges, and overall are very sharp. Some edges show a complex recrystallization but aside from one small chip there is no damage. This rare variety of Apatite is also known as Strontiapatite and it seems that the crystals from Karnasurt Mountain are the best ever found. The color ranges from green to yellow and there is a faint fluorescence. Choice and large example of this rare Apatite.
