Precious diamond brooch of the Art Déco in platinum, France around 1930

In the Art Deco era, a new basic shape for jewellery began its triumphant advance: The shield, designed as an elongated oval or polygon. It met the 1920s preference for graphic forms, because the large surface could be filled with powerful geometric patterns. The brooch here demonstrates this fashion impressively. The slightly wavy outline is filled inside with jagged, powerful lines, all of which are set with sparkling Old European Cut diamonds. An additional large diamond of 0.75 ct is set in the center of the design, held in place by a polished hexagonal frame. The brilliant cut diamond is particularly pure and shines in fine white: a true highlight of this magnificent piece of jewellery. A total of 6.41 ct of diamonds have been worked into the brooch. An independent appraisal has confirmed the quality of the gemstones and comes with the piece of jewellery. The brooch sets the diamonds in white platinum, which with its cool and elegant luster was the fashion material of the Art Deco period. The hallmarks of the jewel show that it was created in France. Its powerful forms allow us to date it to the years around 1930.

Jewellery in elegant, cool and noble white - that has been the dream of jewellery designers since the late 19th century. But the technical possibilities put a stop to this dream for some time. Diamonds were available, but the tricky part was the question of the right metal. At first, only silver was available to create white jewellery from, but the metal tarnishes and can leave discolorations on skin and clothes. From the 1900s onwards, platinum was used more and more, but it was difficult to work with and much more expensive than gold, so that platinum was usually only used on the front of the pieces. It was not until 1912, when Pforzheim succeeded in producing white gold on a mass scale by cleverly alloying gold with other metals, that the way was clear for all-round white jewellery. However, it was to take until after the First World War for the new metal to really establish itself: with the fashion for Art Deco, however, there was no stopping it.
