Modernist Sterling Silver Swivel Ring | Black Onyx & Abalone Shell | Rotating Double-Sided | Adjustable Open Shank | Handmade 925

Handcrafted with bold Modernist conviction, this one-of-a-kind sterling silver ring is a study in kinetic artistry. At its heart is a double-sided swivel mount — riveted to rotate freely — that showcases a deep black onyx cabochon on one face and a luminous abalone shell on the other, each bezel set with quiet precision. Wear it mysterious with the onyx forward, or flip it to reveal a cascade of iridescent blue, green, and violet. Two moods. One ring. Entirely handmade.

The open, expandable shank adjusts comfortably starting at a size 7. The sterling silver has developed a natural patina over the years — an honest mark of age and authenticity that only deepens the piece's character. Marked 925 and clearly the work of a skilled studio hand, this ring embodies the spirit of the Modernist studio jewelry movement: thoughtful in construction, bold in presence, and built to be worn.

A rare find for collectors of wearable art, kinetic jewelry, or anyone drawn to pieces with more than one story to tell.
