Most opals are pale colors, but the Mexican fire opal is anything but. In India, Persia and Central America people used to believe this was the ultimate stone of love. The stories said that the gem was so colorful because it was made in paradise waters. Mayans and Aztecs loved fire opals. They referred to it as the “stone of the bird of paradise.” This particular ring features a round Mexican fire opal, with diamonds and 14k white gold.
