Object Description

This stunning, fine and impressive antique brooch has been crafted in 15ct white gold with a platinum setting.

The pierced decorated, symmetrical Art Deco design is ornamented with eight claw set round faceted sapphires, totalling 3.20 carats.

The angular design to the centre of the brooch incorporates four of the aforementioned sapphires encompassing an impressive feature pavé set 0.15ct Old European cut diamond.

This central sapphire and diamond design is set in relief to an angular cut-cornered border, incorporating twelve pavé set eight-cut diamonds and four Old European cut diamonds.

The remaining four sapphires flank a collet set Old European diamond, in a linear arrangement segmenting the rectangular frame.

Either end of this geometric Art Deco frame incorporates a individually collet set Old European round cut diamond.

The brooch secures to the reverse of the setting with a hinged bar and safety clasp.

This stunning antique Art Deco brooch has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 15ct gold and platinum.

This impressive brooch is supplied with an independent diamond grading report certificate for the feature diamond, in addition to an independent diamond grading report card for the supporting diamonds and sapphires.
