Antique Art Deco 8.64ct Diamond and Platinum Brooch Circa 1935

1920 - 1940
For Sale by AC Silver
Description

A stunning, fine and impressive antique Art Deco 8.64 carat diamond and platinum brooch; part of our diverse antique jewellery and estate jewelry collections.

This stunning, fine and impressive antique diamond brooch has been crafted in platinum.

The pierced decorated, elliptical shaped platinum frame is ornamented with a central feature collet set 0.69ct transitional modern brilliant round cut diamond.

The symmetrical iconic Art Deco frame is embellished with a further ninety-four pavé set diamonds, in a combination of square, baguette, Old European and eight cuts.

The impressive design secures to the reverse with a hinged pin and security clip fastening.

This Art Deco diamond brooch has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

This impressive Art Deco brooch is supplied with an IDGL diamond grading report certificate for the feature stone, in addition to an IDGL diamond grading report card for the supporting stones.

This Art Deco style platinum antique diamond brooch exemplifies the geometric symmetry, clean lines and refined craftsmanship associated with the Art Deco period. The platinum setting enhances durability and diamond brilliance, while the balanced design creates strong visual presence without excess ornamentation. Particularly suited to milestone birthdays, anniversaries, retirement celebrations, weddings and major personal achievements, it functions as both a versatile statement accessory and a treasured heirloom.

Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone.

Condition

This stunning Art Deco brooch is excellent quality, set with an impressive feature diamond displaying a fine white colour, brilliance and presence.

The impressive high colour graded supporting diamonds display a fine white colour and brilliance.

The brooch is an excellent gauge of platinum and is in excellent condition.

Reflections in photographs may detract from the true representation of this fine example of Art Deco jewellery/estate jewelry.

An antique Art Deco brooch from circa 1935, created in platinum and set with brilliant and square-cut diamonds. The silver-coloured piece takes the form of an elongated geometric openwork plaque, featuring a central bezel-set round diamond within a symmetrical lattice of pavé-set stones, interspersed with horizontal rows of channel-set square and baguette diamonds and secured with a hinged pin and security clip on the reverse. The brooch measures 0.308 cm high, 2.46 cm wide, and 5 cm deep. It belongs to the Art Deco style, displaying clean lines, pierced decoration, and balanced symmetry. In a contemporary home, such an antique accessory is typically stored in a jewellery box or displayed within a cabinet when not being worn for milestone events, weddings, or formal evening gatherings. The construction comprises ninety-five diamonds totalling 8.64 carats, mounted in an elliptical platinum frame with openwork details, circular collet settings, and a hinged pin mechanism.

FAQs

Art Deco brooches from the 1920s and 1930s feature bold geometric shapes, symmetrical patterns, and a focus on architectural structure. They frequently incorporate platinum settings with intricate openwork and high-grade diamond arrangements.

Art Deco fine jewellery predominantly utilised platinum for its strength and ability to create delicate mountings without sacrificing structural integrity. Diamonds, particularly in geometric cuts like baguettes and square cuts, were set alongside platinum to achieve a crisp, monochrome aesthetic.

Authentic 1930s pieces typically feature hand-cut diamonds such as European or single cuts, fine millegrain detailing on platinum edges, and period-accurate hallmarks. The precision of the hand-carved openwork and geometric symmetry also distinguishes original items from modern reproductions.

An antique diamond brooch can be pinned to the lapel of a tailored jacket, secured at the neckline of a plain silk blouse, or attached to a satin clutch bag. It can also be worn in the hair using an adaptable clip attachment for formal occasions.

Clean platinum and diamond jewellery using a soft brush with mild soapy warm water, then dry thoroughly with a lint-free cloth. Store the piece individually in a lined box or velvet pouch to prevent diamonds from scratching other gemstones or metal surfaces.
