Some gemstones are admired for their color. Others are remembered for their patterns. This Peruvian Blue Opal offers both, featuring rare natural color banding that creates a scene reminiscent of distant landscapes or an unfamiliar world viewed from above. No two stones display these formations in exactly the same way, making each example genuinely individual.
At 17.59 carats and measuring 16.76 x 14.57 x 11.10 mm, this oval cabochon Peruvian Blue Opal displays an Ice Blue color with translucent clarity. The beautifully developed bands move through the stone naturally, creating depth, contrast, and visual interest far beyond what color alone can provide. The substantial size allows these unique formations to be fully appreciated from every angle.
Completely untreated and naturally formed, the gemstone preserves its original character exactly as nature created it. Stones displaying this combination of Ice Blue color and distinctive natural patterning are rarely encountered. This stone fits comfortably into a collection built on real taste.
All Peruvian blue opal is entirely natural and untreated. No dyeing, heating, impregnation, or coating is used or required. The blue color is a permanent natural product of the copper trace element chemistry in the Andes geological environment. Learn more about Peruvian Blue Opal.
