A gold vermeil pendant necklace with a vertical row of black onyx channel-set down the center of a rectangular bar. Two raised, polished edges frame the line of stones, giving the pendant a dimensional, architectural profile. The deep black onyx reads with a grounded, understated intensity against the warm gold, geometric and quietly bold rather than flashy. It hangs from a fine curb chain that keeps the pendant centered at the chest. The polished finish holds its shine through regular wear. Wear it on its own or layered with other gold chains for a minimal, modern stack.
