Light opal has been produced in good quality in the northern part of Hungary since ancient times. Black opal, on the other hand, was unknown for a long time, but was discovered in 1902 from Lightning Ridge, New South Wales, Australia. Shortly before that, light opal was produced from Queensland and New South Wales in Australia, and with the discovery of black opal, Australia outperformed Hungary. Black opal is said to have the highest quality when the stone has a very bright play color, and poor quality when it has a part that is dull and has no play color. Also, when you change the viewing angle of black opal, another play color appears. The cause of this play color has been scientifically clarified, but it is strange that the power of nature created this. The mere mineral opals, which cannot be called gems, are widely distributed near the surface of the earth, and with the probability of thousands or hundreds of illions of them, nature accidentally created gem opals. Furthermore, the characteristic of black opal, which shows a completely different pattern depending on the viewing angle, has a mysterious beauty not seen in other gemstones. Black opal contains less water contain than light opal and is less likely to crack, but its hardness is 5 to 6 and it is easily scratched and weak to impacts, so it is important to wear it as not to give any impact.
