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 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.
Quartz (Cumberland habit) with Hematite -USA classic
stock #18AX-17-304
Chubb Lake, St. Lawrence County
New York, United States
4.7 x 3.5 x 2.8 CM (miniature)
price: $330
Spring 2020

Doubly terminated Quartz crystals with classic "Cumberland" form in a cluster dusted with small Hematite crystals. In incredible condition, this certainly looks like a superb vintage English specimen but it is much more unusual, being from Chubb Lake in Northern New York, USA. The locality has been closed for some years but during a brief period some amazing specimens were found. This habit was wrongly called "Beta Quartz" for a time and many old labels reflect that. This specimen has fine form, the crystals are undamaged, it is possible to see inside the Quartz through glassy faces to see dense inclusions. Not often available, this was in the William Hladysz collection.
Tremolite - chatoyant terminated crystals
stock #20.1-137
North Gouverneur, St. Lawrence County
New York, United States
7.4 x 4.6 x 2.8 CM (cabinet)
price: $330
Spring 2020

St Lawrence County of northern New York state is a legendary classic zone for mineral collectors. From time to time new finds are still made often in the isolated Skarns. This significant Tremolite was collected by Skylar Alverson in 1974 and remained in his collection until his passing. Individual crystals reach 4.4 CM and have deep green translucent to transparent faces some showing chatoyance. There are even a few zones of gem grade which could be faceted. In fine condition, no damage except for a small attachment at the base where it was attached, and a few clean contacts where other crystals had grown. A choice example similar to yet rather different from a small find made in 2019, Tremolite is not often an esthetic mineral and this is quite choice.
Quartz (Cumberland habit) with Hematite
stock #18.1-366
Chubb Lake, St. Lawrence County
New York, United States
2.2 x 1.9 x 1.7 CM (thumbnail)
price: $260
Spring 2020

A USA classic Quartz from Chubb Lake, New York, this is a perfect thumbnail with textbook form. The crystal is complete all around, undamaged, a floater with sharp faces and a sparkling dusting of Hematite in tiny crystals. The Quartz is also included with the same sparkling Hematite which can be seen clearly inside the faces. This locality has been closed for many years and is remarkably similar in its mineralogy to the old British localities of the Cumberland Iron mines., This piece could easily pass as British (and as a very fine piece) but it is actually much more uncommon from this small but significant US locale.
Hexagonite - rare terminated Mg Tremolite
stock #19.1-377
Gouverneur Mine, Fowler, St. Lawrence County
New York, United States
2.8 x .8 x .3 CM (thumbnail)
price: $800

A rare, choice gem clear thumbnail of lilac color Hexagonite (var of Tremolite). The termination on this is complex being made of many tiny points in a tapering structure. Transparent with some color zoning seen when backlit. I believe that St. Lawrence County is the only place where this mineral occurs being found at just 4 locations. However only the Gouverneur Mine ever produced any of this sort of clear terminated crystal and not many of them. This was named when it was thought the crystal form was Hexagonal, however it was later determined to be Monoclinic. The crystal here is in fine condition, has clear striations along the prism faces and a very rich color.
Diopside -Classic gem crystal with Tremolite
stock #19.1-356
DeKalb, St Lawrence Co.
New York, United States
3.6 x 1.5 x 1.2 CM (small miniature/ large thumbnail (toenail))
price: $575

A fine old DeKalb, New York Diopside crystal with exceptional transparency and color. This has a "crown" of altered Tremolite that adds a nice accent. These encrustations were usually removed by mechanical means but this is still intact and I think gives an nice touch to the crystal. Some typical contacting on the rear and one side, overall the condition is excellent with far better than usual luster.
Quartz with Hematite
stock #18.AX-398
Chubb Lake, St. Lawrence County
New York, United States
2.2 x 2.1 x 2.1 CM (thumbnail)
price: $390

A superb thumbnail- doubly terminated Quartz from Chubb Lake that looks remarkably like a fine English (Cumberland area) Quartz. This has inclusions of sharp Hematite crystals and a few on the exterior of a few faces as well. The crystal is quite transparent but densely included with the Hematites so it seems murky inside. In flawless condition, this has very sharp edges and almost non-existanct prism faces (they are under 1 mm in size). This locality has been closed for decades and dates back to the 1850 vintage. Good pieces of this quality are quite rare, certainly less common that their British counterparts.
Fluorite - gem clear
stock #AX-20-237
Penfiled Quarry, Penfield, Monroe County
New York, United States
3.2 x 2.3 x 2.3 CM (thumbnail)
price: $360

An ultra clear sharp and glassy Fluorite cube perched on Dolomite. Choice thumbnail or small miniature of a Penfield New York Fluorite, this was collected more than two decades ago. Flawless with no damage at all even under strong magnification. The matrix is clearly seen through the Fluorite, which I would describe as a clear colorless ice. In some light however a very slight hint of blue is seen. A modern USA classic, New York Fluorites are relatively rare, and are prized when perfect and esthetic.
