Mexican fire opal is a glassy, sometimes transparent variety of opal best known from Querétaro in the south of the country. Like other opals, the gemstone forms from silica-rich water filtering through porous sandstone, depositing the mineral to be heated and pressurized into the beautiful gem. Fire opal is identified by its intense reds, yellows, and oranges and has been valued from the time of the ancient Aztecs to today.

This pendant contains a polished 0.828" gem of Mexican fire opal set into a sterling silver bezel. It comes with an 18" silver chain in a padded black jewelry box.
