EXCELLENT. This 18ct Gold old mine-cut Diamond solitaire ring is in excellent condition. The 0.36ct Diamond is secure within its settings with all of the claws firmly intact. There is some tiny wear to the surface of the Diamond, but this is imperceptible when worn and rather adds to its vintage allure. The construction of the piece comprises an old Diamond in a vintage shank and setting dating to 1989. This means that the antique Diamond is in a robust setting and has a shank that is secure around your finger, allowing you to wear it with the utmost confidence!
