All original Art Deco black star & Frost one of a kind ring with diamond shape Calibré cut black Onyx and a beautiful Emerald step cut center diamond. In the early 1900’s diamonds with a hint of warm color and few flaws with good cutting were prized and sought after. We believe this was a custom design privately commissioned ring because of the unique one of a kind design.
