It is common for jewelry buyers to underestimate the role the metal alloy of their ring plays in the value of a piece. Shoppers are drawn more to the stone itself as well as the way it is set. However, ignoring the metal can have disastrous consequences. Following is a look at how the overall price is affected by the metal you choose. Yellow Gold The stock metal option for pairing with diamonds, yellow gold is one of the oldest metals there is. It gives off attractive color and brightness, and works best with diamonds carrying a hint of yellow in them. White Gold White gold contains metals like silver or palladium, besides the pure gold of course. The former give it a color that, upon plating with Rhodium, appears white. White gold costs less than yellow gold, but is more secure and scratch-resistant. Platinum Platinum is rarer than gold, and more expensive as a result. It is only ever used in pure form, and has hypoallergenic properties that preclude skin allergies, as well as heavy resistance to breaking chipping and cracking. If you can afford it, a diamond with platinum ring is the best way to ensure your ring will last longer.
