Mexican Opals

We will meet mineral collector Bob Boisvert as he describes his visit to the opal mines of Mexico. Mexican fire opals consist of silicon dioxide or silica spheres arranged in an orderly pattern with iron oxide dispersed throughout. It’s the iron oxide that gives the Mexican fire opal its distinctive brilliant flame-like colours of yellow, orange, and red. The three most important attributes of the fire opal are body colours, transparency, and play of colour (differing colours when viewed from various angles.)
