Sphalerite - gem crystal on Quartz
stock #24.1-158
Empire State #4 Mine, 3900 foot level, Balmat, St. Lawrence County
New York, United States
3.5 x 2.7x 2.2 CM (thumbnail)
price: $480


A killer thumbnail with a flawless gem clear Sphalerite twin perched on contrasting Quartz crystals. From the incredible new find of these Sphalerites at Balmat, New York in the #4 Mine at 3900 feet down. There were quite a number of nice thumbnails in the find, but just a few of this quality and esthetics, most were very quickly snapped up. Certainly destined to be classics, the better specimens from this locality are modern mineral treasures. Bright glassy luster, yellow-orange color and perfect clarity.

Pecoraite ps after Millerite with Millerite
stock #24.1-179
Sterling Mine, Antwerp, Jefferson County
New York, United States
6.4 x 3.3 x 2.8 CM (cabinet)
price: $290


Pecoraite can be seen as a greenish alteration of Millerite crystals along with some unaltered Millerite in vugs. A quite rare specie worldwide and also rare from the famed Sterling Mine locality, this specimen was in the collection of Skylar Alverson which he obtained in 1980. The matrix is the classic Iron ore most likely Hematite with tiny Quartz, Dolomite and Chalcopyrite crystals. The hairlike crystals are mostly brassy unaltered Millerite but some show the alteration and are no longer metallic. Millerite from Sterling Mine is quite sought after, the Pecoraite is much more rare and the two together are a nice combination. Please note, these are quite tiny crystals, well visible by naked eye but really not a display type specimen, it is best appreciated with magnification.

Tremolite
stock #21.1-038
North Gouverneur, St. Lawrence County
New York, United States
3.3 x 1.6 x 1.3 CM (thumbnail)
price: $160
Fall 22

A single terminated prism of yellow-green Tremolite from the Skarns of St. Lawrence County, NY. An older specimen collected by Skylar Alverson more than 40 years ago. Skylar had several localities he mined in this region some of which he kept secret through out his lifetime. The Tremolites of this area have become famed for the size, sharpness and overall quality of the crystals. This is a choice thumbnail with good transparency and luster.

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.

Fluorite -gem clear with Anhydrite crystal inclusions
stock #AX-34-034
Walworth Quarry, Walworth, Wayne County
New York, United States
7.4 x 5.3 x 5.2 CM (cabinet)
price: $2950
new year 2021

A USA classic from the Walworth Quarry. Perfect, glass-clear transparent Fluorite sits exposed on Dolomite matrix. The cube is 2.3 CM diameter and several flat needle like crystals of Anhydrite are clearly seen inside. The Fluorite has the most desired blue color and the matrix is seen perfectly through the crystal. This specimen is sawn on the base which is commonly done to collect these without damage in the very hard matrix. The saw marks are not really noticeable in most display positions. We can arrange for a prep lab to use pneumatic tools to roughen the sawn surface if desired though this is certainly not needed, and incurs a cost. Walworth Fluorites are highly desired in fine condition like this, some many have at least some damage. These are a modern classic, the quarry is still operating and twice each year collecting is allowed for one day. Some years little or nothing good is found, such good undamaged specimens are very rare and highly prized.

Spinel on Chondrodite - USA classic
stock #21.1-043
Amity, Orange County
New York, United States
4.6 x 3.8 x 2.9 CM (miniature)
price: $340
new year 2021

The famed old Spinel locality of Amity was one of the first of the Eastern USA Classic locales. The exact original locality may be lost today but the Skarns in the area have yielded some nice Spinels from time to time. This is an older piece with fine octahedral Spinel crystals on a crystalline orange Chondrodite matrix. Ex Hladysz collection, this has sharp form, nice arrangement and excellent luster with no damage. Displays very well from several angles and better in person.

Quartz - gem
stock #20.1-308-(LW328)
Lasselville, Town of Ephratah, Fulton County
New York, United States
1.8 x 1.4 x 1.2 CM (thumbnail)
price: $130
new year 2021

A perfect thumbnail of gem-clear Quartz with a form that looks a lot like a Herkimer Diamond but is from the less well-known locality of Lasselville in Fulton County, NY. No damage, with fine esthetics, collected in 1972 by Larry White. This had been in his thumbnail collection for more than 40 years.

Danburite -Classic USA Locale
stock #19.1-318
Russell, St. Lawrence County
New York, United States
7.3 x 7.5 x 4.1 CM (cabinet)
price: $475


A fine, well crystalized old Danburite from Russell, New York. A classic of the Historic St. Lawrence County region, this specimen is from the late Ingeborg Burggraf collection. Several zones on the matrix host dense clusters of Danburite crystals with several habits, most being transparent to translucent and fairly glassy. The crystals reach over 1.3 CM though the majority are smaller. Uncommon on the market, the clear type like this are usually somewhat smaller in size this is well above average for quality.
