Opal characteristics

オパールSpeaking of opals, they are fantastic because of the variety of colors they can be seen in.play-of-color" Because opal contains all the colors of the rainbow, alchemists long ago called it the "philosopher's stone." Its colorful shimmer, reminiscent of water, is created by the large amount of water it contains at the molecular level. Its Japanese name is "opal stone," derived from the fact that white opal resembles egg white. However, some opals do not exhibit play-of-color. Opals that exhibit play-of-color are called precious opals, while those that do not are called common opals. Opals are also known by many names, so we will introduce a few of them.


■Black Opal
A rainbow of play-of-color sparkles against a dark background. A dreamy black opal reminiscent of the aurora borealis. It is one of the most expensive opals, and those with a clear play-of-color and red inclusions are especially rare and highly valued. It is primarily found in Australia, but is also found in Mexico and Ethiopia.
ブラックオパール
■ Fire Opal
Fire opals exhibit fiery play-of-color. Considered the second most valuable after black opals, their play-of-color appears on a red to orange body color. The two stones contrast with the calm atmosphere of black opals and the passionate appearance of fire opals, even though they are the same stone. Some fire opals also contain common opals, which do not exhibit play-of-color. Because fire opals are primarily produced in Mexico, they are often mistaken for Mexican opals, but Mexico also produces water opals, which are sometimes sold as Mexican opals, so be careful. In addition to Mexico, fire opals are also mined in Ethiopia and Brazil.
ファイアーオパール
■Water Opal
Water opal is a refreshing stone with a colorless, transparent to clear blue body color and play-of-color. Those with particularly high transparency and clear play-of-color are sometimes called crystal opals because of their beauty, as if water is inside the gemstone. It is a type of Mexican opal and is mainly produced in Mexico. It is also found in Ethiopia.
ウォーターオパール
■ Hyalite Opal
While precious opals are commonly known for their play-of-color, we'd like to introduce one common opal that does not have play-of-color. This is hyalite opal, which develops bright colors under ultraviolet light. When exposed to black light, it glows like neon, making it another mysterious gemstone. It is a rare gemstone that is difficult to produce even among opals, and its name comes from the Greek word "hualos," which means glass.

There is also an anecdote from the Australian Aborigines that says, "The Creator rode a rainbow down to the earth, bringing news of peace to all mankind."
