The fiery, warm glow of the fire opal beguiles jewel enthusiasts the world over. This radiant orange simply cannot be overlooked! The fire opal, which, like the other opals, consists of silicic acid with a relatively high water content, was named for its colour.
The colour itself comes from fine traces of iron oxide. With a hardness of between 6 and 6.5 on the Mohs scale, however, the fire opal is among the somewhat sensitive gemstones which require a protective setting, especially when worn as a ring stone.
