Description

This striking statement piece is a masterclass in Mid-Century Modern design, specifically drawing from the bold, architectural movements of the late 1960s and early 1970s. The ring features a centerpiece of genuine Petoskey stone, a fossilized rugose coral unique to the Great Lakes region that flourished over 350 million years ago. This ancient fossil is expertly polished into a smooth oval cabochon, showcasing the distinctive hexagonal "honeycomb" patterns that make each stone a prehistoric work of art. The stone is securely housed in a thick bezel setting, elevated above a dramatic and highly stylized split-shank frame.

The band itself is an avant-garde architectural feat, constructed from solid sterling silver with a substantial total weight of 9.6 grams. The design utilizes negative space and geometric cutouts, creating a cage-like structure that is both sturdy and visually lightweight. Despite its bold presence, the smooth interior and balanced weight ensure a comfortable fit for a size 11 finger. The lack of traditional hallmarks is common in custom artisan-crafted pieces of this era, and the metal has been professionally scratch-tested and verified with acid to ensure its high-quality sterling purity. This ring serves as a bridge between natural history and modernist art, making it an ideal choice for collectors of unique geological specimens or vintage brutalist fashion.

Vintage Condition & Care: All items listed are previously owned and used unless otherwise stated. Please expect signs of wear such as scuffs, blemishes, or imperfections.
