October’s birthstone, Opal, displays a unique play-of-color that some say looks like fireworks, lighting, or galaxies trapped inside the stone. The patterns and colors that result from the stone’s interaction with light make each opal one of a kind.

There is no right or wrong in choosing an opal that appeals to you, but knowing what to look for is essential. GIA’s Opal Buying Guide will make sure you know the basics before you buy.
