Mexican fire opal, prized for its vibrant orange and red hues, is a unique variety of opal found in Mexico, particularly in the states of Querétaro, Jalisco, and Guerrero. Unlike common opals, Mexican fire opals often display vivid flashes of color known as "play-of-color," adding to their allure and beauty. The term "fire" in its name refers to the opal's fiery appearance rather than any internal phenomenon. In ancient times, Mexican fire opals were revered by indigenous cultures like the Aztecs and Mayans, who believed they held mystical properties and represented the sun's energy. Despite its popularity, Mexican fire opal is relatively soft compared to other gemstones, making it more prone to scratches and damage. Today, Mexican fire opal is treasured by jewelry enthusiasts and collectors for its intense color and unique play-of-color, adding a fiery touch to various pieces of jewelry and decorative items.
