Mexican Fire Opal: Gemstone and Jewelry


Mexican Fire Opals, also known as the Mexican Opal, is a versatile gemstone that emanates a vibrant orange, yellowish, red, or sometimes brownish hue. It is a unique stone that can be found in various parts of the world, but its superior quality is associated with the mines located in Mexico. These mines, particularly in the states of Hidalgo and Queretaro, produce some of the most exquisite Fire Opals in the world. In this article, we will explore the background, history, properties, and uses of the Mexican Fire Opal and its contribution to the world of jewelry.



Background and History: 

Mexican Fire Opals have been known to the world since the pre-Columbian era when the Mayans, Aztecs, and other indigenous peoples of Mexico used it for religious, social, and economic purposes. The Mayans, in particular, valued the Fire Opal, believing it to have supernatural powers that could provide guidance and wisdom to its wearer. They were also known to bury Fire Opals with their dead and used them in sacrificial ceremonies to honor their gods.

The Aztecs, on the other hand, traded Fire Opals as a form of currency, valuing it equally with gold. They believed that Fire Opals were a symbolic representation of the sun and bestowed them with healing properties. Furthermore, the Aztecs believed that Fire Opals could also protect them from harm and danger, hence, often wearing it as a talisman. It was not until the 19th century that Fire Opals began to attract international attention.

A few Mexican mines had produced a significant number of Fire Opals, some of which were notable for their size and quality. Most of these mines were being operated by the Mexican government, who had prohibited foreigners from acquiring them for some time. However, in 1827, a British merchant, who was also a mineral collector, convinced Mexican authorities to allow him to purchase some Fire Opals, and so began the exportation of these glittering gemstones to the rest of the world.




Mexican Fire Opals are unique because of their internal structure, which is different from other opals. The Fire Opal owes its colorful display to the presence of iron oxide and traces of manganese and copper. The stone is transparent to translucent, and in some cases, even opaque with play-of-color that results from the diffraction of light on the internal structure of the stone.

The Mexican Fire Opal has a Mohs hardness scale rating of 5.5 to 6.5, which makes it softer than many other precious and semi-precious stones. This means that it is more vulnerable to scratching than other gemstones like rubies, sapphires, and diamonds. Consequently, Fire Opals require careful handling and maintenance, which includes avoiding extreme temperatures, ultrasonic cleaning, and exposure to harsh chemicals or oils that could change the color or damage the structure of the stone.




Mexican Fire Opals are known for their vivid colors, which include orange, yellowish, red, and a rare green-blue hue. These intense tones make the Fire Opal a favorite among gemstone lovers and collectors. The orange hue is the most common, while the reds are rare and, therefore, significantly more valuable. The Mexican Fire Opal's color can be influenced by the lighting, with the intensity of the illumination affecting the brightness and saturation of its hues.
