Mexican opal forms in volcanic rock rather than sedimentary deposits. This gives it a transparent to translucent body with warm orange, red, and yellow colors from iron oxide content, rather than the play-of-color flash common in Australian opal.
Mexican fire opal rates 5.5–6.5 on the Mohs hardness scale. This makes it softer than quartz, so rings benefit from protective settings and removal during physical work or hand washing.
No. All Mexican opals in our collection are natural and untreated. We do not carry synthetic, dyed, or smoke-treated opal material.
Our stones come from the primary mining regions of Querétaro, Jalisco, and Magdalena in central Mexico, where opal has been extracted from volcanic deposits for nearly two centuries.
