That is the correct spelling of "opal" (semi-precious stone, hydrated silica).
Well, opals are a very beautiful gem, and quite valuable. They are actually remains of ancient, fossilized beings, and have qualities that diamonds do not have, and unlike diamonds, which can be created in a lab, are very unique. Australia is very well known for it's opal mining systems. My source: the Opal Museum in Sydney, Australia.
Opals are merely a gemstone and contain no "powers". The only power an opal confers is the ability to instill in humans a sense of the wonder of nature that such a rich play of colors and beauty can be locked into the structure of the stone.
