Palladium is resistant to corrosion, oxidation and tarnishing and is very durable. Because it is low maintenance, lighter than platinum, 12% harder than platinum and nearly half the weight, palladium can be an especially good choice. Not only is it lighter, but Palladium is also an extremely strong metal, making it scratch resistant and an ideal ring for any man or woman that has a hands on job or active lifestyle.
Palladium was discovered by William Hyde Wollaston in 1803 and has been used as a precious metal in jewellery since 1939. As recently as 2001, palladium was more expensive than platinum and rarely used in jewellery due to the issue of casting - the technology to efficiently cast palladium as jewellery did not exist then. Palladium is extremely difficult to cast well because it is a veritable oxygen sponge when molten; it therefore requires a very controlled melting environment. However, the casting problem has been solved and its use in jewellery has increased because of a large increase in the price of platinum and a drop in the price of palladium.
