No reserve price Orange, Brown Sphalerite - 61.79 ct - Instituto Gemólogico Español (IGE)

Sphalerite is a fascinating and relatively rare mineral prized by collectors for its brilliant luster and striking colors, ranging from deep browns and oranges to yellows and even greens and reds. Its high dispersion makes it sparkle with fire more intensely than many other gemstones, which can rival even diamonds in brilliance when cut properly. Weighing 61.79 carats, this specimen is notable for its impressive size; sphalerite specimens of this scale and quality are exceptional. While not traditionally used in mainstream jewelry due to its softness (around 3.5-4 on Mohs hardness scale) and cleavage, sphalerite remains a prized collector's gem and decorative stone. Certified by the Instituto Gemológico Español (IGE), this specimen's properties and authenticity have been professionally verified. Its multifaceted color palette of orange and brown hues, combined with excellent brilliance, makes sphalerite a captivating mineral both scientifically and aesthetically.
