Large Art Deco Platinum & Diamond Rectangular Brooch

A fabulous platinumDerives from the Spanish word ‘platina’ meaning ‘little silver’. Acknowledged since the 1900s, platinum’s durability and natural brightness has been and still is today highly treasured A metallic element prized for its rarity, whiteness, high tensile strength and insusceptibility to corrosion, platinum first became widely used in jewellery in the late ninete… 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.
