Cheryl Eve Acosta’s Mer de Verre collection is for ocean lovers who appreciate the beauty of marine life. Her cascading blue glass enamel Sting Ray Ring emits color from its copper surface and is inspired by floating sting rays that live in the tropical waters. Subtle variations in color and metal growth may result due to the unique process. None of her enamel rings are resizable because of fused glass on the surface. Also available in oil gray.
