Cartier 3.28 Carat Art Deco Diamond Ring A rare and ravishing beauty. From Cartier-Paris, circa 1930s, a gorgeous, bright-white European-cut diamond, weighing 3.28 carats, sizzles between a pair of long and slender straight baguette diamonds (.50 carats total) set in platinum.
A belle epoque tiara, 1908, by Chaumet. Made for the Marquis de Talhouet, a classic scrolling foliate tiara, with large circular diamonds at the centre of each scroll and topped by a larger, cushion-cut diamond.
The diamond necklace, part of the French crown jewels was collier aux quartre rivieres, a four-strand diamond necklace which originally had two large shoulder bows. Set with 222 diamonds weighing a total of 363 carats.
Given to the British Museum by an anonymous donor, the centerpiece of this ring is a brilliant-cut blue diamond weighing nearly 16 carats. The stone itself shows signs of being cut in the 1920s, however, the setting--a mount of platinum with three-stone baguette diamond shoulders suggests the style of the 1940s-1960s.
