COMMENTS: We love a good timeless engagement ring, like this one from the Retro era of the 1940’s. This style engagement ring made it’s debut during the Art Deco era and continues to be among one of the most desired designs today. During the Retro period the design was modified to be slightly heavier than the Art Deco design. This small modification increased the overall durability of the ring to last a lifetime and more. The center of the ring features a GIA certified 0.64 carat round brilliant diamond. GIA is the only recognized and non-disputable gemological laboratory in the world, you can shop with confidence in this ring and your investment. The setting is composed of solid platinum and is fashioned in a timeless three diamond design. The tapered baguette accent diamonds total 0.16 carats, bringing the total carat weight in the engagement ring to 0.90 carats. Pictured as received from a local estate. Excellent estate condition with minimal wear indicative of age.
