Our gold products are either 14k or 18k. 14K is 58.3% pure gold mixed with 41.7% other metals that give gold the hardness to be durable in jewelry. 18K is 75% pure gold. White gold is an alloy of metals that give the metal hardness and whiteness. Nickel is normally used in this alloy. White gold products, because they are not pure white, are normally plated with rhodium to give the metal a bright white luster.
Our platinum products are made with 95% pure platinum and 5% irridium.
