Large Art Deco Platinum & Diamond Rectangular Brooch

329M
Rare Find
Written by Olly Gerrish

A fabulous brooch that was made in the 1920s. It is typical of the period with its angular design and has been set with graded and good white well matched diamonds. The brooch is not flat as the platinum almost looks like it has been woven in to the design. There is wonderful millgrain detail throughout. This is when the edges of the platinum have been worked with a knurling tool to produce tiny beads, hence the French name “Millgrain” meaning a thousand beads. The reverse is equally well made with attention to the settings which have been filed and polished. It is a stunning piece of jewellery.
