Dutch Art Deco Bar Brooch with Diamonds and Sapphires, Circa 1920

A striking Dutch Art Deco bar brooch, crafted circa 1920 in 18K yellow gold with a platinum or white gold top. Its elongated form is set with sapphires and old-cut diamonds, framed by subtle rose cuts and senailles. Once part of a transformable jewel, it now stands alone as a refined piece echoing the streamlined glamour of the Roaring Twenties.

Style
Art Deco - Art Deco is an eclectic artistic and design style which had its origins in Paris in the first decades of the 20th century. The style originated in the 1920s and continued to be employed until after World War II. The term "art deco" first saw wide use after an exhibition in 1966, referring to the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes that was the culmination of high-end style modern in Paris. Led by the best designers in the decorative arts such as fashion, and interior design, Art Deco affected all areas of design throughout the 1920s and 1930s, including architecture and industrial design, as well as the visual arts such as painting, the graphic arts and film. At the time, this style was seen as elegant, glamorous, functional and modern.

Style specifics
Abstract motives and geometrical forms are quite typical for the Art Deco period. Art Deco moved away from the soft pastels and organic forms of its style predecessor, Art Nouveau, and embraced influences from many different styles and movements of the early 20th century, including Neoclassical, Constructivism, Cubism, Modernism, and Futurism. Its popularity peaked in Europe during the Roaring Twenties and continued strongly in the United States through the 1930s. Although many design movements have political or philosophical roots or intentions, Art Deco was purely decorative.

- When we provide weights, colour grades, and clarity of diamonds, these are approximate unless otherwise stated, as we do not remove diamonds from their settings to preserve the integrity of the piece.

- All diamonds, regardless of their size or shape, in our vintage and antique jewellery are verified as 100% natural by the IJGC laboratory.

- We do not sell lab-grown (synthetic) diamonds.

Precious stones
Eighteen sapphires . We did not check if the sapphires are lab produced or not as this information has no influence on the value of this jewel. Natural sapphires and lab produced sapphires were both used in this era, rather more for their effect than for their intrinsic value.
It is a very common practice to treat gemstones to intensify their clarity or colour. The item in question has not been tested in this regard.
