CJ Recht Moonscape Ring in Sterling
The Moonscape Ring may be the boldest metal ring in the CJ Recht collection. The deeply textured Moonscape is set on a square shank which keeps it from rolling around. and it looks cool too. The circular top is heavily textured with alternating light and dark ridges which create a stunning surface-of-the-moon look. The Moonscape Ring is also available in bronze and oxidized sterling silver. Make a statement with this one, which is $290 in sterling silver.
