1 pcs Orange, Yellow Sphalerite - 21.00 ct - International Colored Gemstone Association (ICA GemLab) - Rare Gem Mined From Spain

Sphalerite is a fascinating and rare mineral primarily composed of zinc sulfide, often valued by collectors and gem enthusiasts for its exceptional luster and range of colors. This particular specimen features beautiful orange and yellow tones, contributing to its appeal. With a substantial weight of 21 carats, it is notably larger than many gem-quality sphalerite crystals. Sphalerite's optical properties, including a high dispersion rate, give it a brilliance that can surpass even diamond in fire, though its relatively low hardness (3.5–4 on Mohs scale) limits its everyday wear potential. Mined from Spain, this gem carries both geological and regional significance, as Spain is known for producing some high-quality sphalerite specimens. The confirmation of quality by the International Colored Gemstone Association (ICA GemLab) adds credibility, making it an attractive option for collectors or those seeking unique gemstones beyond the traditional sapphire, ruby, and emerald. Its striking yellow to orange hues, rarity, and size make it an exceptional natural treasure born from hydrothermal mineral deposits.
