    RARE GEMSTONE: SPHALERITE- 15.24 CT.
    Spain

    Sphalerite (ZnS) is the principal ore of Zinc. Although widely distributed around the globe, it is not usually found in transparent crystals light enough in color and with sufficient clarity, to furnish facetted gems. The mines of Picos de Europa in the Pyrenees of Spain are one of the exceptions to this rule. Here orange-red globular crystal groups attain sizes of 2 to 4 inches in diameter. Clear areas within these aggregates are occasionally saved for cutting by master gem cutters skilled enough to handle this difficult material. This golden round brilliant gemstone shows the exceptionally brilliant adamantine luster and extreme dispersion that Sphalerite is known for. There are several tiny, unobtrusive inclusions near the the girdle, otherwise the stone is quite clean.
    Measurements: 14.4 mm in diameter , 15.24 cts.
    Offered at no reserve.
