Moonscape ring blackened sterling silver
The Moonscape Ring is now available in blacked (or oxidized) sterling silver. This is the boldest ring in the CJ Recht collection. The ring is set on a square shank which keeps it from rolling around. The circular top is heavily textured with alternating light and dark ridges which create a stunning effect. The Moonscape Ring is also available in bright sterling silver and bronze.
