This exquisite vintage Sterling Silver ring features an approximately 5.5 mm AA-quality natural Ammolite cabochon bezel set in a beautifully crafted mounting. The vibrant red, orange, yellow, and green flashes of the gemstone stand out against the detailed metal accents, making it a standout piece for any jewelry collection. Stamped 'sterling 925', this classy size 6.75 circa 1980s ring weighs approximately 3.88 grams. The top of the ring is 28.4 mm at its longest, over a 3.3 mm wide band for comfortable wear. The ring displays a pleasant patina typical of its age and has been cleaned but not polished.

Ammolite, a captivating organic gemstone, is celebrated for its vibrant, iridescent play of color, reminiscent of a kaleidoscope. Originating from the fossilized shells of Ammonites—ancient marine mollusks—primarily found in the Bearpaw Formation of Alberta, Canada, this gem displays a dazzling spectrum of hues, including reds, greens, blues, and purples. Its unique optical phenomenon, caused by light interference within the Aragonite layers of the shell, makes each Ammolite specimen distinctly individual. Ammolite's relatively soft nature necessitates careful handling and often involves protective treatments to enhance its durability and brilliance. As a rare and visually stunning gem, Ammolite holds both geological and aesthetic significance, making it a sought-after treasure for collectors and jewelry enthusiasts alike.
