Object Description

A stunning French antique 2.79 carat aquamarine and 4.96 carat diamond, 18 carat white gold and platinum brooch; part of our antique jewellery and estate jewelry collections

This stunning, fine and impressive antique aquamarine brooch has been crafted in 18ct white gold with a platinum setting.

The pierced decorated, oval shaped setting displays a central feature collet set 2.79ct cushion cut aquamarine.

The feature aquamarine is flanked to the upper and lower borders with a pavé set 0.35ct and 0.33ct Old European round cut diamond.

The millegrain decorated frame is embellished with a further seventy-four pavé set diamonds, in a combination of Old European round and eight-cut.

The brooch secures to the reverse with a hinged pin and push fit clasp.

The rim of the setting is hallmarked with the French import mark (owl); this mark is used for finished articles brought into France to be examined by the French assay office.

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

This stunning antique brooch is supplied with two independent diamond grading certificates, in addition to an independent diamond and gemstone grading report card for the supporting stones.
