Details
Circa 1950, this ring is built around a genuinely rare centerpiece: a cushion-cut Ceylon sapphire of 10.12 carats, GRS certified, its deep, velvety royal blue holding rich saturation from every angle of the stone's broad, well-proportioned facets. Four gold prongs lift the sapphire above the hand, letting light travel through its corners with a glow that only fine Ceylon material achieves.
Flanking the sapphire, four diamonds cut as trapezoids and trillions — weighing approximately 0.80 carat in J-K color, VS-SI clarity — step down the shoulders in crisp, architectural lines of platinum-set white, a cool counterpoint to the warmth of the 14k yellow gold frame and shank.
At 5.94 grams and sized 6.75 with room to resize, this ring has the classic three-stone poise of mid-century design — a substantial, gem-forward ring equally suited to daily wear or an evening out.
