china bridal jewelry Not all opals will change colors

Zveřejněno na podle Kingjy

Opal, a beautiful gem that makes people reluctant to look away, conquer the world with its unpredictable colorful colors. As the viewing angle changes, the opal will show ever-changing colorful colors, which is most suitable for social occasions such as dance parties and banquets.

The composition of opal is actually very simple, it is water-containing silica. The reason why opal is precious is mainly due to its unique fantastic optical special effects. How did Opal produce such a magical effect?

Opal silica is not a crystal, but a small, amorphous spherical shape. So obviously, Opal is not a crystal. These silica balls in opal are closely packed together, and they must meet strict and harsh conditions in order to produce color changing effects. Především, these small balls must be basically the same size, not big or small. Za druhé, the diameter of these small balls must be within a certain range, not too large or too small. You might as well imagine the internal structure of Opal as countless piled up ping pong balls. When the diameter of the ping pong balls meets certain conditions, light will diffract and interfere in the gaps of the balls, resulting in a strange color-changing effect. You know, in the natural state, it is not easy to meet these two conditions at the same time, which makes the opal with the color changing effect extremely precious.

Black opals are not all black, but opals with a darker base, such as dark blue, hnědý, atd.; the base of white opals is usually white. Imagine, under what circumstances will Opal’s color changing effect become more clear and eye-catching? Is it on a dark background or a light background? Obviously, on a dark background, the color change will be clearer.

The value of black opal is much higher than that of white opal. In the international market, the price of high-quality black opal is about thousands of dollars per carat, while white opal is only tens to hundreds of dollars per carat.

In addition to Australia, Mexico is another important opal origin. Not all opals have a peculiar shadow effect, and Mexican opals usually do not have this effect. They are called fire opals because they resemble fire in color. Však, fire opal will not be fiery red. It can be a variety of warm colors, such as yellow, pomerančový, atd. The redder the color, čím dražší to je.
