For example, 14K yellow gold is 58% gold, and 42% copper and silver. We generally recommend 14K gold rings for anyone who uses their hands for manual labor because it is strong and durable. 18K gold is 75% gold, with the balance mixed with copper and silver.
Alloys also can be used to actually change the color of the gold. We add nickel to the yellow gold to create the white tone. However, if you are sensitive to nickle, we have options of making the ring with palladium at additional cost on a special order basis. Rose gold has a higher copper content, which produces the red tone.
