Vintage 1950’s Birks Platinum Cabochon Sapphire French Diamond Cocktail Ring

A refined cocktail ring by Birks of Canada, the historic Montreal house founded in 1879 and known for its precise workmanship and understated luxury. Crafted circa the 1950s in platinum, the ring is centered by approximately 7.00 carats of deep blue natural cabochon sapphires. The composition is accented by approximately 1.50 carats total weight of oversized tapered baguette, French cut, and round brilliant diamonds, arranged with a strong sense of structure and balance that reflects the period’s design language. The contrast between the saturated cabochons and the crisp geometry of the diamond cuts underscores the quality of both materials and execution. The ring measures 0.60 inches north to south, weighs 9.3 grams, and is a size 6.
