Palladium is one of the platinum group metals but is considered a precious metal in its own right. Palladium is naturally white which means that there is no need for rhodium plating. Palladium is more precious than silver. It is less dense than platinum, being nearly half the weight, so larger necklaces and bracelets can be made, capable of bearing larger gemstones with minimal gain in overall weight. For the same reason, palladium is considered to be a good choice for earrings although unlike platinum it is not hypoallergenic. It is often recommended as a good alternative to 9Kt white gold for male bridal consumers due to it never needing re-plating.
