Sphalerite 8.60 Cts.

Natural Sphalerite

Coming in a gorgeous array of citrus hues, Sphalerite is the most outstanding Spanish gemstone, and highly regarded for its amazing Diamond-like characteristics and premium quality. Spanish Sphalerite beautifully displays, bright oranges, reds, and yellows with a highly-desirable medium saturation (strength of color) and tone (lightness or darkness of color), the marketplace ideal. As a rare exotic, Spanish Sphalerite is typically restricted to specialist collections and museum displays, even though it has some remarkable optical properties. Brittle, difficult to polish, and possessing six directions of perfect cleavage (easily exposed, continuous flat surface breaks that reflect light), Sphalerite is challenging for the cutter. While they can detract from brilliance, inclusions in Sphalerite can increase its fire. Spanish Sphalerite is very clean, displaying exceptional clarity for the type. Similar to Emerald, Sphalerite is classified as a Type III gemstone by the GIA (Gemological Institute of America), gemstones that typically grow with many inclusions in nature, which are usually eye-visible. Sphalerite clarities range from eye-clean (the highest quality clarity grade for colored gemstones as determined by the world’s leading gemological laboratories) to moderately included (minor inclusions visible to the unaided eye).
