Opal Characteristics

オパールSpeaking of opals, they are known for their fantastic colors.Play of color". As opal contains all the colors of the rainbow, alchemists long ago called it the "philosopher's stone." Its colorful shimmer, reminiscent of water, comes from 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 show play-of-color. Opals that show play-of-color are called precious opals, and 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 play of color that sparkles on a dark background. A fantastic black opal that resembles the aurora borealis. It is one of the most expensive opals, and those with a clear play of color and red color are particularly rare and highly valuable. It is mainly produced in Australia, but is also found in Mexico and Ethiopia.
ブラックオパール
■ Fire Opal
Fire opals have a fiery play of color. They are considered the second most expensive after black opals, and their play of color appears on a red to orange background. The calm atmosphere of black opals contrasts with the passionate play of color, even though they are the same stone. There are also common opals that do not show play of color. As the main source of fire opals is Mexico, fire opals are sometimes mistaken for Mexican opals, but Mexico also produces water opals, which are sometimes sold as Mexican opals, so please be careful. Besides Mexico, fire opals are also produced in Ethiopia and Brazil.
ファイアーオパール
■Water Opal
Water opals are refreshing opals that have play of color on a colorless to clear blue background. Those with particularly high transparency and clear play of color are also called crystal opals because of their beauty, as if water is inside the gemstone. A type of Mexican opal, it is mainly produced in Mexico. It is also mined in Ethiopia.
ウォーターオパール
■ Hyalite Opal
Opals are generally called precious opals, which have play-of-color, but we will introduce one common opal that does not have play-of-color. It is a hyalite opal, which develops bright colors under ultraviolet light. When exposed to black light, it shines like neon, making it another mysterious gemstone. It is a rare gemstone that is difficult to produce among opals, and its name comes from the Greek word "hualos" (glass).
