4.22 ct Diamond and 9 ct Yellow Gold, Silver Set Brooch - Antique Circa 1820


This stunning antique diamond brooch has been crafted in 9ct yellow gold with silver settings.

The pierced decorated oval design features an old mine cut diamond, claw set to the centre flanked on either side with slightly smaller old mine cut diamonds.

The central design is surrounded with twenty-two pavé set old mine cut diamonds.

The outer border is embellished with a further sixteen old mine cut diamonds, individually displayed within silver, millegrain decorated collet setings.

This fine example of Regency jewellery secures to the reverse with a hinged pin and closed shut fastening, and benefits from the additional security of a fine link chain with a barrel catch.

The antique brooch is supplied with three independent diamond grading certificates for the feature diamonds, in addition to the diamond grading report card (shown).

This brooch has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 9ct gold and silver.

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.
