Art Deco Style Platinum Old European Cut Diamond Ring SI1 J Size 5.25

Title:
Art Deco Style Platinum Old European Cut Diamond Ring SI1 J Size 5.25

Description

This item is offered on consignment on behalf of a client; all serious and reasonable offers are presented for consideration, and I work diligently to achieve a mutually agreeable outcome.

One (1) vintage ring crafted in platinum featuring a central Old European cut diamond set within an elegant Art Deco-inspired mounting accented by round brilliant and single-cut diamond melee in a pavé setting.

The center diamond measures approximately 6.34 mm and is estimated to weigh approximately 0.90 carat based on its dimensions. The diamond displays a warm J color and would likely grade VS clarity; however, a small chip is present on the girdle, resulting in an overall clarity grade of SI1.

Delicate openwork details, geometric lines, and pavé-set accent diamonds create a timeless Art Deco aesthetic. The ring tests as platinum and offers substantial finger coverage while maintaining an elegant profile.

Condition Notes

Very good vintage condition with light surface wear consistent with age and normal use. The center Old European cut diamond displays a small chip on the girdle visible under magnification, which is reflected in the estimated SI1 clarity grade. The accent diamonds appear secure, and the platinum mounting exhibits minor wear commensurate with age. The shank is slender at approximately 1.13 mm but remains structurally sound. No box or papers are included. Please review all photographs carefully, as they form an important part of the description.
