Over the years Palladium has become extremely popular for many reasons. It is in the Platinum family of metals and is know for shine and durability with a lower cost. Until approximately the year 2001 the metal price was actually higher and when it decreased so did the popularity.
It is also about half the weight of platinum and has an even brighter shine naturally. This can be useful in manufacturing earrings and many other pieces of jewelry that contain large diamonds and gemstones. The metal is absolutely ideal for wedding bands that are worn everyday and will keep the silvery/white luster since that is the color of the metal.
Palladium has also been given one of the four currency codes used in commodity trading in addition to Gold, Silver and Platinum. The precious metal has gained all time popularity, but the traditional metals are still household words for now.
