Large detachable double-clip brooch in platinum adorned with a pavement of scrolling diamonds ranging from 0.01 ct. to approx. 0.35 ct., combining approx. 7.30 ct. of 8x8, old European and old round brilliant diamonds (various qualities). Fine jewelry. Double pin on each of the two parts. Circa 1940. Dimensions: 6.1 x 4 cm. Gross weight: 39.5 g. The transformable jewel of the 1930s/1940s was a huge success at the time. The parts were detached to put one side on the chest and the other on the hat, or like Queen Elizabeth II of England, the two brooches separated by a few centimeters on the shoulder. Today, it can become the jewel of a couple, each wearing one of the two parts, which are reunited in the jewel box at the end of the evening.
