Object Description

A stunning, fine and impressive antique 6.08 carat diamond and platinum, 18 carat rose gold set bar brooch; part of our antique jewellery and estate jewelry collections.

This stunning, fine and impressive antique brooch has been crafted in platinum with an 18ct yellow gold fastening.

The subtly tapering linear setting displays three stunning 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 an 18ct yellow gold hinged pin and safety catch.

The stunning antique diamond brooch has been hallmarked to the pin with the French mark for 18ct gold (eagle’s head) and maker’s mark, and the side of the setting bears the French mark for platinum (dog’s head).

This impressive antique diamond bar 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.
