Object Description

A stunning, fine and impressive, large antique 4.05 carat diamond and 6.07 carat emerald, 18 carat yellow gold and platinum Art Deco style brooch made by Garrards & Co Ltd; part of our diverse antique boxed jewellery and estate jewelry collections

This stunning 1930s antique emerald and diamond brooch has been crafted in 18 ct yellow gold, with a platinum setting.

The brooch is comprised of an impressive and large yellow gold ribbed irregular oval toroid shape, accented with a platinum sporadic array emanating from the hole to the centre.

The non-uniform array is embellished with nine impressive claw set marquise cut diamonds and fifteen stunning mixed fancy cut Colombian emeralds, totalling 6.07ct.

The toroid shaped setting is interwoven with two curvilinear strands, incorporating forty-three channel set baguette cut diamonds; these strands bear the same alignment as the aforementioned emerald array.

This large antique brooch secures to the reverse with a yellow gold hinged pin and safety clasp.

This antique diamond and emerald brooch is fitted to the original hinged leatherette presentation case with a satin and velvet lined interior, securing with a push fit catch.

This case retains the original outer card presentation box; this is an additional feature of the piece.

The interior of the cover of the case and surface of the box features the retailer’s mark ‘By Appointment of Her Majesty the Queen, Goldsmiths and Crown Jewellers, Garrard & Co Ltd, Crown Jewellers, 112 Regent Street, London, W.1’.

This magnificent emerald and diamond brooch has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 18 carat gold and platinum.

This impressive brooch is supplied with an independent diamond grading report card*.

NOTE: * The Gemmological Certification Services (GCS) lab has verbally accredited the emeralds originating in Colombia and verifies that the gemstone shows indications of minor clarity enhancement.

“Rather than regarding inclusions in coloured stones as harmful, in small sizes and numbers that do not in any way detract from their beauty, they should be regarded as adding to desirability, for they provide identifying characteristics.”
