Authentic John Hardy sterling silver men's Bedeg Lava signet-style ring with black sapphire.  Measures 18mm wide across the finger and weighs 18.7 grams. The black sapphires are different sizes and shapes and are set with space in between so you have a dark, textured background with just a little pop of sparkle when the light hits the sapphires.  It reminds me of concrete or granite that has a few specks of sparkle sprinkled throughout.  It's a very masculine and understated look with just the right amount of "bling"  Retail price is $695.  Come with storage pouch and polishing cloth.
