We frequently suggest a platinum white gold ring since it is a precious metal, but if you're a savvy buyer, you should be aware of some of its disadvantages as it matures. Remember that white gold isn't the only type of yellow metal used to make jewelry. White metals like palladium, nickel, and silver are mixed with 24K yellow gold to produce white gold. After these metals have been thoroughly combined, the resulting white gold product is "rhodium plated" to give it a brighter, whiter appearance.
