The Story

A super chic diamond and onyx ring, perfect for a lover of the Art Deco movement.  Made circa 1920s-1930s, it features a gorgeous antique Old Mine cut diamond that predates with setting. The beautiful, chunky cut stone weighs approximately 0.80 carats.  Old Mine cut diamonds are our favorite, they sparkle and move light unlike any other.  Surrounding the center diamond are twenty rose cuts diamonds accenting the piece.  The ring finishes with four carved onyx pieces. 

Made in platinum, this incredible ring is quintessentially Art Deco with its geometric shape and onyx and diamond combination.  This chic piece would make a fantastic engagement ring, and is a classic for generations to come.
