A stunning antique Art Deco French 4.53 carat diamond and platinum brooch; part of our diverse antique jewellery and estate jewelry collections

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

The pierced decorated, geometric Art Deco rectangular frame is ornamented with a central feature collet set 0.66ct transitional modern brilliant round cut diamond.

The principal stone is surrounded with four pierced decorated arched incurved designs, accented with enveloping collar motifs to the outer frame.

The symmetrical arched motifs incorporate seventy-four pavé set diamonds, in a combination of transitional modern brilliant round and eight cuts.

The cut cornered rectangular frame is embellished with a further thirty-two pavé set diamonds.

The stunning design secures to the reverse with a hinged pin and push fit fastening.

This antique Art Deco brooch is supplied with an independent diamond grading certificate for the feature diamond, in addition to an independent diamond grading report card for the supporting stones.

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.

This stunning antique Art Deco brooch is exceptional quality, set with very high colour graded diamonds displaying a fine white colour, brilliance and presence; the high graded diamonds indicate the exceptional quality of the piece.

The brooch is an exceptional gauge of platinum and is in excellent condition, with a clear French hallmark to the setting.

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