Mexican opal jewelry features opals sourced from the volcanic regions of Querétaro, Jalisco, and Magdalena. These deposits produce two main varieties: fire opals with orange-to-red body color and crystal opals with transparent to translucent bases. Mexican opals form in rhyolitic lava flows and register 5.5 to 6.5 on the Mohs hardness scale. Our collection pairs these North American stones with .925 sterling silver settings.

Mexican opals form in volcanic rock and often display warm body colors without play-of-color, while Australian opals form in sedimentary rock and are known for their color play against white, black, or boulder backgrounds.
Mexican fire opals range from affordable to high-value depending on color intensity, transparency, and size. Deep red-orange specimens with good clarity command the highest prices in the market.
Clean Mexican opal with a soft damp cloth and avoid ultrasonic cleaners, harsh chemicals, and extreme temperature changes. Store pieces separately to prevent scratches from harder gemstones.
