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

The subtly tapering linear setting displays three feature Old European cut diamonds to the centre, accented with fifteen pavé set Old European round cut diamonds graduating in size.

This antique brooch secures to the reverse with a hinged pin and safety catch.

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

This impressive antique brooch is supplied with three independent diamond grading report certificates for the feature stones, in addition to an independent diamond grading report card for the supporting stones.

Such bar brooches with larger set diamonds are becoming increasingly difficult to locate.

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.
