If you think gold jewelry is only gold, you are most definitely mistaken. Today, gold is available in a rainbow of hues, from white to pink and green to gray. And of course, there is always yellow.

The color of gold is altered depending on the metal that it has been mixed with. Due to manufacturers variations in their alloy mixtures, there can be slight differences in items. This can cause one necklace to be a bit whiter than another of the same karat value by a different maker.

Yellow gold is made of an alloy of gold and copper, while mixing nickel, zinc, copper, tin and manganese with gold creates white gold. Combining gold, copper and silver will give you a pink or rose gold. High levels of silver or cadmium combined with gold give a green gold. Blue gold is created with the same high levels of silver or cadmium that green gold has, along with the addition of iron. Use an even greater amount of iron and you will end up with gray gold.

Lower karat gold jewelry items generally show a better depth of color than higher karats items. Always look for the hallmark indicating the karat weight of the piece of jewelry and enjoy the fun you can have with gold's many shades!
