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.
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.
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.
