Diamond and 18kt White Gold Art Deco Brooch C. 1925

1900 - 1920
Description

A dazzing and beautiful 18kt solid white gold bar brooch which is set with three large and brilliantly sparkling old European cut diamonds (VS1-VS2 clarity) and almost clear in colour, (tested as F-G).

The three principal diamonds totalling 0.89 carats and there is also a small triangular diamond at the tail of approximately 0.1 carats, the setting in the design of the Ace of Clubs.

The fixing pin is straight and strong and has a slide lock. This Art Deco brooch dates from c. 1925 and is in excellent original condition with only very light and fine surface marks consistent with occasional careful use. Valued by a local reputable and well established jeweller at £2,250 and the diamonds graded and reported on by the Word Gemological Institute. The Valuation Certificate and WGI report will be supplied with the brooch.

With fully insured next day tracked UK postage on this lovely brooch and a presentation box included in my price. This is a lovely piece when worn, really dramatic and eye catching - it looks a million dollars! The fitting with reassuring slide catch are robust enough to wear without worry.

Dimensions are:

5.4cm long, 1cm tall, 0.8cm deep the tie pin weights exactly 4g

This Art Deco brooch dates from c. 1925 and is made of 18ct solid white gold in a silver colour. The design includes a central trefoil motif formed by three large old European cut diamonds in prong settings, accompanied by a smaller triangular diamond accent at the tail. The piece incorporates a long bar pin setting with a straight pin and a slide lock fastening on the reverse, along with visible surface marks consistent with occasional use. Measuring 5.4 cm long, 1 cm tall, and 0.8 cm deep with a weight of 4 g, the brooch is supplied with a valuation certificate and a gemological report. It is worn pinned to garments as an ornamental accessory.

Art Deco bar brooches from the 1920s are characterised by sleek, geometric lines, horizontal alignment, and the widespread introduction of platinum and white gold settings to highlight white diamonds.

Jewellers during the Art Deco era primarily utilised 18ct white gold or platinum, combined with old European cut diamonds, rose cut diamonds, and geometric filigree or milgrain metalwork.

Authentic pieces typically display hand-cut diamonds such as old European or single cuts, period-correct metal hallmarks, safety catch mechanisms specific to the early 20th century, and precise geometric symmetry.

When not being worn, antique brooches can be styled in a modern interior by displaying them on velvet-lined trinket trays, under glass cloches, or mounted within framed shadow boxes on a dressing table.

Clean the brooch gently using warm water, mild soap, and a soft-bristled brush, ensuring the piece is completely dried afterward; store it separately in a fabric-lined box to prevent surface scratches.
