Retro Certified Natural No-Heat Sapphire Diamond Cocktail Ring Yellow Gold 1940s

About the Item

A striking vintage sapphire and diamond cocktail ring from the 1940s, crafted in polished yellow gold. The centerpiece is a certified natural no-heat cushion-cut sapphire of 4.00 carats, displaying a deep blue hue, secured by eight delicate claws. Surrounding it, a tiered halo of eight round brilliant-cut diamonds and eight circular sapphires creates a dazzling floral effect, all set in open-back settings to enhance their brilliance. The collet leads to an elegant D-shaped solid shank with gracefully open split shoulders, a refined touch of elegance for those who appreciate discreet details.
