SORRY ITEM SOLD

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.


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 within this stunning piece of antique jewellery.


This impressive antique diamond bar brooch is excellent quality, set with stunning diamonds displaying a fine white colour, brilliance and presence.

The brooch is an excellent gauge of platinum and gold and is in excellent condition, with clear French hallmarks to the pin and setting.


Reflections in photographs may detract from the true representation of this fine example of antique jewellery/estate jewelry.
