SOLD Sphalerite- gemmy crystal, classic locality
stock #SOLD 18-1-417
ZCA corporation / Pierrepont Mine, Pierrepont, St Lawrence County
New York, United States
2.7 x 1.9 x .4 CM (thumbnail)
price: $0


A flat, transparent Sphalerite crystal with cognac color from the ZCA Mine in St Lawrence County, New York (USA). This is large, lustrous and very well-defined for this famed locality. The edges are very slightly rough as is typical of all larger crystals from here, but overall this is exceptional with a gemmy interior. This looks at first glance to be untwinned, but under magnification there is a small notch that may indicate a twin plane. Either way the crystal is much more impressive in person, the termination is complete though a bit crude on one edge and with backlighting it glows very nicely.

Sphalerite - triplet macle
stock #21-FC-010
Baia Mare
Maramures, Romania
4.3 x 2.4 1.6 CM (miniature)
price: $390


A sharp, textbook perfect triplet or macle twin of Sphalerite on contrasting Dolomite. From the classic Romanian locale of Baia Mare, this is highly lustrous in person. The main twin is a prominent 1.8 CM triangle nicely centered in the center of this cute miniature specimen. Sphalerite is a mineral that is very often twinned, but this habit of triple joining is quite unusual.

Sphalerite - gemmy crystals
stock #18-AX-418
ZCA corporation / Pierrepont Mine, Pierrepont, St Lawrence County
New York, United States
2.2 x 1.8 x 1.4 CM (thumbnail)
price: $240
Late Summer 2021

A very lustrous Sphalerite thumbnail. This is a sharp and fully transparent honey-yellow crystal from a classic Northeastern US Locality. The ZCA Mine in Saint Lawrence County has been the source of many fine minerals. This specimen is twinned as seen and has several complex growth structures on some faces as well as some flat glass-like ones as well. A few rough edges from contacts but overall in very good condition. What looks like inclusions inside the crystals in the photos is actually other crystals on the backside seen through the clear Sphalerite. Not many of these make it to the market, this specimen is from an older collection and was collected at least 25 years ago.

Sphalerite (Cleiophane) and Galena on Quartz
stock #13.1-158
September 9th Mine, Madan Ore field, Rhodope Mts.
Smolyan Oblast, Bulgaria
11.8 x 8.2 x 4.4 CM (cabinet)
price: $950
Early summer 2021

A very fine cabinet display specimen of gemmy yellow to dark green Sphalerite crystals on a contrasting drusy Quartz boxwork matrix. The Quartz druse sprinkled with cubes of Galena some of which have grown next to the Spahlerites. A classic association from the Madan area of Bulgaria, this is much better than most and in excellent condition. This presents the majority of the Cleiophane (gemmy Sphalerites) in a chain like cluster. These photos are not backlit but with a good light behind the Sphalerites they glow a vivid bright yellow-green which is fantastic in person.

Sphalerite (Rubyjack) historic specimen.
stock #AX-35-207
Quapaw tribal area, Ottawa County
Oklahoma, United States
7.8 x 3.7 x 2.2 CM (cabinet)
price: $380
new year 2021

A very unusual looking specimen of Sphalerite with some bright red and darker crystals perched on a thin shard of Chert matrix. Ex Wallace Gould Levison collection, he obtained this piece in 1909 from the "northeast corner of the Quaparo Indian Territory, A zinc mine there" his notes give the source as George R. Osborn who was located in Kansas City, MO. This area we know today as the Quapaw territory of Ottawa County, Oklahoma. Mining had begun on the Indian territories in 1908 so this is a very early specimen. The area became a very important Lead Zinc supplier though the Indians were not compensated as agreed. Mining ended in 1950 but for a while this was the world's largest Pb Zn source. The specimen has well-formed crystals with the largest 2.3 CM. Smaller crystals are translucent to transparent and this is quite esthetic in person. We include a photocopy of Levison's original collection ledger page with this specimen. A very nice quality Tri-state classic specimen with unusual early provenance from an important US collection.

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.

Sphalerite var. Schalenblende
stock #AX-35-108
Eagle Mine, Gilman District, Eagle Co.
Colorado, United States
5.8 x 3.6 x 2 CM (cabinet)
price: $240
new year 2021

An oddity from Colorado, this unusual botryoidal Sphalerite is a complete floater, with a dark yellow-green color. This variety (Schalenblende) of Sphalerite is known in a very few other specimens from the Eagle Mine; most Sphalerite from there was the more normal lustrous black crystals. In fine condition, from the collection of Skylar Alverson obtained by him from Charlie Bowman in 1984. Excellent for a Colorado collection and a very rare Sphalerite from any place in the USA.

Sphalerite and Siderite - fine Cornish
stock #15.1-450
Ale and Cakes Mine, Gwennap
Cornwall, England
4.2 x 2.8 x 2.6 CM (miniature)
price: $800


Super lustrous black Sphalerite crystals on contrasting crystals of Siderite. This piece is from the noted Cornish collection of Lewis Barton (his label is included), and is a superb Sphalerite from anyplace in Cornwall and likely the best known from the Ale and Cakes Mine (which is a great name for a mine)! Despite a few edge nicks and contacts the overall quality and condition is really fine. A choice addition for any good Cornish or UK suite.
