Cartier has been the jeweler of kings and the king of jewelers since 1847 — and a diamond ring from the house of Cartier, purchased in the 1960s and accompanied by its original documents, represents something far beyond a purchase: it is a piece of history. The center stone, a 4.33-carat round brilliant diamond graded D color and SI1 clarity by the GIA, is flanked by two tapered baguette diamonds in a setting of pure platinum — a composition of absolute classical authority. D color is the pinnacle of the diamond grading scale: completely colorless, with a purity and brightness that is immediately apparent to the eye. At 4.6 grams of platinum, the ring is refined and wearable, designed to be worn and admired for generations. Preowned, very good condition, with original Cartier documents and GIA certification. A once-in-a-lifetime acquisition.
