Palladium has obvious benefits when compared with other white precious metals. It has none of the tarnishing or wear problems associated with white gold; palladium is approximately half as dense as platinum, being 12 grams per cubic centimetre as opposed to 20 grams for 950 platinum, and 16 grams for 18 carat white gold; and the identical article is therefore much less expensive in palladium than platinum, as it contains less weight of a significantly cheaper metal. A 950 palladium alloy is approximately half the price per gram of 18 carat gold at present, although additional making costs narrow the difference considerably. The table below demonstrates even bigger ‘perceived value’ benefits if 500 palladium is substituted.
