During the period 200-100 BC, Opal was used as a precious gemstone, which was favored by the imperial royal family in ancient Rome. The early Greek royal family believed that Opal could give the power to forge ahead and predict the future. The Arab elders believed that Opal came from heaven and felt the lightning in the sky through it. Ancient legend Opal originated from the Latin Opalus, English name is opal, transliteration is Opal, Opal. It means "the beauty of the gemstones." In Europe, Opal was known as a Roman Empire and was of great value. According to Pliny, the Nunnery of the Senate has a very beautiful opal. He is very fond of it. At that time, the ruler Anthony asked him to give it, otherwise he would be exiled. As a result, Nonining chose to go exile and refused to offer Opal to Anthony. Place of origin Leiden Ninrich, New South Wales, Australia, is the only mining area identified internationally for producing black opal. Just like the darling of the gemstone investment community like Tanzanite, the only place of production is less, and the high quality is less, and the non-renewable resources are gradually becoming more and more rare in mining. In the rest of your life, you can encounter such a set of black opals, and you don’t have a gemstone game. form Opal is a gelatinous or liquid silica that remains in the formation cracks and caves and deposits into amorphous amorphous gemstones, which also contain animal and plant residues such as trees, carapace and bones. During the formation of opal, the silica solution deposits like a magma into the gaps and empty ore deposits of the inland strata. The sedimentation occurs at a depth of about forty meters from the surface, and the sediment increases by one centimeter every five million years. The thickness of the deposits began to slowly solidify with climate change during the first and second million years after this phase. Opal is a part that has not been bonded to other deposits and has been hard for a long time. Why can the science of Opal concentrate the color of the starry sky? Color change game Opal can appear in a variety of body colors: white body color can be called albumin; black, dark gray, blue, green, brown body color can be called black protein; orange, orange red, red body color can be called fire protein. The surface color of Opal changes with the intensity of light and the transformation of the visual angle, just like the game of playing hide-and-seek in various colors. Opal change color Opal change color: also known as color spots. There are irregularly arranged, differently colored films in the same opal. In the same color film, the light color is not uniform. Due to the size of the globular opal particles regularly arranged in the opal, only the scattered light and opal are opalescent when the spherulite size is significantly smaller than the visible wavelength; only when the spherulite size is slightly larger than the wavelength of visible light or half wavelength of visible light When the white light is diffracted and interfered, it exhibits a full-spectrum color from purple to red or some spectral color that is more monotonous. When the incident light direction or the gemstone position is rotated, the light color also changes. Identification A good opal stone produces a flame-like appearance. This appearance has only been found in very few substances, but it has not been found in other gemstones, and it has attracted people's interest and intoxication in ancient times. This phenomenon of flame-like appearance caused by diffraction of light is called color change. This is the most important identifying feature of opal stone and its main attraction as a gemstone.
