Vintage Coffin-cut Black Onyx Ring-Cerys

Design overview

This vintage black onyx ring centers a 6 × 8 mm coffin-cut stone in a tapered geometric outline. Round black onyx and moissanite side details create a contrasting frame around the dark center, while the 1.5 mm band keeps the lower profile narrow. Straight coffin edges, compact accents, and the contrast between the black center and its side materials define the top view. Material options include plated silver, 18K gold vermeil, and 10K, 14K, or 18K gold choices; select the exact material shown for the variant you want.
