Overall Condition: Very Good
Condition Notes: Structural ingenuity and decorative artistry intersect in this brilliantly engineered diamond ring. At first glance, the piece presents as a substantial, sculptural design, with a richly textured 18k gold exterior framing the center stone in commanding fashion. Closer examination reveals that this gold shank is fully hinged and functions as a removable jacket.

The 18k mounting opens and separates, peeling away to reveal a refined platinum engagement ring beneath. In its streamlined configuration, the platinum shank offers a far more understated presentation, allowing the center diamond to stand independently with crisp, tailored lines. When reassembled, the gold jacket transforms the piece into a bold statement ring with dramatic scale and contrast. *While the platinum engagement ring is fully sizeable, the 18k gold jacket mount my not be sizeable due to the presence of the hinge by the sizing area.
