A very rare metal, it requires the mining of 2-3 tons of platinum ore to produce enough metal to create a single ring.
Platinum was refined and introduced into the jewellery trade in the early 1900s. Platinum's hardness and strength suited the "clean" geometric designs of the Art Deco period in the late 1920's and 1930's. These designs frequently incorporated the newly developed angular Baguette and Emerald diamond cuts, the hardness of platinum allowing the jeweller to create a delicacy of design whilst retaining great strength.
The twenty-first century has seen a resurgence of interest in platinum in jewellery designs, probably for the first time since the 1930's. The high cost of the raw metal, its high melting point, its hardness, and its difficulty in fashioning, makes platinum one of the most expensive precious metal used in jewellery. However its unique properties offer a strength and security greater than that of other precious metals, as well as allowing the working jeweller a great freedom of expression in design.
Cellini uses platinum extensively, having developed a specialised expertise in using this difficult metal. Its hardness and durability makes it the metal of choice used in many of the ring designs and high quality settings.
