Origin

The fire opal used comes from Mexico, one of the world's most renowned sources for this opal variety. Deposits in Querétaro, Jalisco, and Hidalgo are particularly famous for their intensely colored, clear to translucent fire opals.

Mexican fire opal differs from other opals by its own body color and not primarily by play of color.
