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.
Calcite -light violet
Hyatt Mine, Talcville, St. Lawrence County
3.4 x 2.1 x 1.7 CM (small miniature/ large thumbnail (toenail))
Late Summer 2018
A single scalenohedral Calcite crystal with a light Violet hue. Sharp with a slight milky zoning, this is in good condition as well. Calcites from this locale are not often available.
Tremolite crystal in a sharp prismatic form nicely exposed on matrix. Ex S. Alverson Collection, this was collected over 25 years ago. The most prominent crystal is doubly-terminated and there are a few lesser crystals on the matrix as well. This find was not the well known Selleck road location but a small prospect that was kept private and never published. The color on this piece is a lighter hue of green than the Selleck material. Choice.
