| Gold color is created by mixing in other various elements with gold to create a gold alloy with various
colors. No matter which gold color is created, the pure gold is always present in the correct percentage. For example, 18K gold will
always have 75% pure gold contained in the jewelry, while the rest of the alloy colors can be altered to create a different color. One
color for example is the popular white gold. It is created by mixing in nickel to give it a whiter appearance. For more information
regarding the percentages and elements used, see the chart below.
