Mohave turquoise - composite turquoise stabilized with copper to create the distinctive blue-purple color and metallic inclusions that make Mohave one of the most visually distinctive turquoise varieties - in two shapes together in 18K yellow gold over sterling silver creates a ring where the Mohave's specific character is shown across two different cut forms. The fancy shape and marquise cuts each display the composite material's swirling blue-purple-copper pattern differently, creating a two-stone ring where both stones are from the same material family but each shows it from a different angle. A ring with a specific, unusual material identity.
