North Gouverneur, St. Lawrence County
3.3 x 1.6 x 1.3 CM (thumbnail)
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.
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.
