Vintage Sterling Silver Indigo Sapphire Signet Ring
A handsome, elegant sapphire signet ring is set with a double row of dark, mysterious, indigo blue sapphires. They are a very dark blue, almost black, and gorgeous. Round cut, each of the 8 stones is approximately 2.5mm in diameter.
The setting is 1/2″ wide by 1/4″ tall. The ring size is 7.5 US.
The ring is unmarked and tests as sterling silver, likely rhodium plated to keep the brightness. The stones are calibrated, and likely lab-created.
