Antique Platinum Diamond Ring, Art Deco Era

A refined and beautifully balanced Art Deco–era ring (circa 1920s–1930s), crafted in enduring platinum and showcasing the architectural elegance for which the period is celebrated. At the center is a sparkling round diamond, approximately 0.65 carats, held in a sculptural, geometric setting that draws the eye with timeless sophistication.

Flanking the center stone are side diamonds totaling approximately 0.40 carats, thoughtfully arranged to enhance brilliance and symmetry. The ring’s front measures approximately 9mm across (about 0.35 inches), offering a graceful presence on the hand without overwhelming scale. Subtle openwork and crisp detailing along the setting reflect classic Art Deco design principles—clean lines, symmetry, and fine craftsmanship.

With its substantial platinum construction and elegant proportions, this ring is ideal as an antique engagement ring or a distinguished addition to a curated estate jewelry collection.
