Onyx is a stone that've been around for centuries, and our version captures that sense of age-old intrigue but sill looks modern. Cast from 18-karat gold-plated silver, the band gently wraps the finger and it's tipped with a polished translucent black onyx stone. It coordinates beautifully with the matching earrings. Materials 10x8mm. Onyx 18k Yellow Gold Over Sterling Silver (1 Micron thickness). An additional layer of palladium plating is applied to protect gold from natural oxidation of silver.
