fire opal stone--- Technically, the only type of opal known as 'fire opal' is Mexican Fire Opal, mined in Mexico, which usually has a distinct orange coloring. However, the term has been used to describe any kind of opal (normally a black opal shows it best) which displays a significant amount of red colouring. Red of course is the rarest colour, so these are quite valuable.
