1.55ct Diamond and Synthetic Ruby, 18ct Yellow Gold Brooch - Antique Belgian Circa 1930


A stunning, fine and impressive antique Belgian 1.55 carat diamond and synthetic ruby, 18 carat yellow gold, 18 carat white gold set brooch in the Art Deco style; part of our diverse antique jewellery collection

SKU A1946

This stunning double clip Belgian 1930's brooch has been crafted in 18ct yellow gold with an 18ct white gold setting.

The pierced decorated frame has a three-dimensional, organic, leaf style form embellished with two feature old European round cut diamonds, collet set to the centre of each segment of the clip brooch.

The brooch is further ornamented with pave set eight-cut diamonds, graduating in size within a sweeping design to the centre.

Six scrolling fronds emanate from opposing sides along the curvilinear design.

The antique Art Deco brooch is further accented with seven, channelled set, baguette cut synthetic rubies*, flanked with a row of old European round cut and eight-cut diamonds, graduating in size, collet set to each section of the double clip brooch.

This versatile 1930s duette brooch may be worn as a single item, or as a matching pair.

Both components may be held on the unifying, 18ct yellow gold frame which secures to the reverse with a hinged pin fastening with security clip.

Alternatively, the designs may be removed from the frame and worn singly or as a pair, securing by virtue of the hinged locking feature incorporated to the reverse of each.

The hallmarks to the reverse include the Belgian country marks and an 18ct gold hallmark (750).

The diamond brooch is supplied with an IDGL diamond grading report card.

NOTE * In 1837 Gaudin made the first synthetic rubies by fusing potash alum at a high temperature with a little chromium as a pigment. Natural rubies and synthetic rubies look very similar on general observation. Synthetic rubies have a different internal colour banding and crystal structure which can only be identified under specific test conditions. It was common practice to incorporate synthetic rubies to impressive pieces of antique jewellery.

*NOTE: Contrary to what many people may think, the word "synthetic does not mean fake when it comes to gemstones. In order for a material to be called "synthetic" it must have a natural counterpart. A synthetic ruby will have the same chemical composition as a natural ruby and therefore have an almost identical appearance to the naked eye.

The first ruby formed by melting two smaller rubies together was in 1817, and the first microscopic crystals created from alumina in a laboratory in 1837.

Common practice was to set and enhance fine quality antique jewellery with vibrant and colourful synthetic stones.

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.
