Quartz with Hematite
Chubb Lake, St. Lawrence County
2.2 x 2.1 x 2.1 CM (thumbnail)
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
Penfiled Quarry, Penfield, Monroe County
3.2 x 2.3 x 2.3 CM (thumbnail)
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.
Sphalerite on Quartz
Clinton, Onieda County
3.5 x 2.7 x 2 CM (small miniature/ large thumbnail (toenail))
A bright lustrous Sphalerite crystal perched above a sparkling Quartz matrix. From an important 1987 find in Clinton, NY. this is an excellent clean example. The Sphalerite shows the complex form that is typical with multiple twinning and is translucent, light passing through gives a rich yellow to rootbeer color. Can be trimmed to a thumbnail if desired. A modern classic from the Northeastern USA not often available.
A main gem clear Tremolite prismatic crystal sticks straight up from a complex mix of Tremolite, Diopside and Calcite crystals. From the classic locality of Pierrepont in St Lawrence County, New York, this was found a few decades ago by the late Skylar Alverson, a legendary collector in the area. In excellent condition the main crystal is well terminated and has a pleasing blue-green color. The matrix is sawn on the back and bottom to allow it to be collected intact, the cut marks are not visible on display. A very fine example of the specie and is typical of a choice specimen from the famed Skarn gash veins of the region.
ZCA Mine number 4, Balmat, Balmat-Edwards District, St. Lawrence, Co.
3.9 x 3 x 2.2 CM (miniature)
Ex. New York State Museum collection specimen with especially sharp, fine crystals. The cubic habit Magnetites from Balmat are renowned as unique in the mineral world. This is a superb specimen with sharp, complete and lustrous crystals. Very few of these are in such clean condition and the form of this is especially distinct. Most cubes show the stepped cubic striations and growth hillocks clearly.
A rare doubly terminated, complete enstatite (Hypersthene) crystal 2 CM long on bright red Alamandine. From the famed Gore Mt Garnet locality that produced huge masses of Almandine years ago. Hypersthene was also fairly common but mostly massive or very poorly formed. This Enstatite is crude but with clear form with a melted edge look. The crystal is perfect, undamaged and nicely perched on the Garnet matrix, this is not typically a pretty mineral but this crystal has charm. This is the best formed and most distinct Enstatite I have seen from the locale, a fine thumbnail for the region.
Sharp, glassy, with catseye effect luster and very well formed, a pure mass of Tremolite crystals. From the now classic Pierrepont locality in St Lawrence county New York, this has fine deep olive green color and is in excellent condition. Collected more 40 years ago by S. Alverson, the chantoyance or catseye effect is striking in person.
Sphalerite -gemmy crystals
ZCA Corp./Hyatt Mine, Talcville, St. Lawrence Co.
2.4 x 2 x 1.8 (thumbnail)
Late Summer 2018
A super thumbnail of fine gem clear Sphalerites that came from Talcville decades ago. in excellent condition, this looks great from several angles and the luster is brilliant. A more modern USA classic these do not turn up very often. The Sphalerites stand out well from the dark matrix making a nice three-dimensional presentation.
