What colors do topaz have? Among many colors of topaz, red topaz is the most valuable. At present, it is only produced in a small part of Minas, Brazil. Because its output is very rare, topaz with pure color and fullness above 10 carat is rare. The value is even hundreds or even thousands of times that of the same grade of blue topaz.
Emperor topaz Emperor topaz was named Shirley topaz. Because its color is like light yellow or dark brown wine produced in Spain, the color is mainly yellow and brown, and the brown components are orange and orange-red. The value of imperial topaz lies in its high color concentration, so the orange-red with higher color is the most valuable.
Pink topaz Pink topaz is mainly made of yellow and brown topaz after irradiation and heat treatment. Mostly pink, light red to light purple or violet. Natural deep pink topaz is the most popular, but this quantity is also relatively small. The key is to have enough purity and no brown or black defects.
Yellow topaz Yellow topaz is slightly lighter than imperial topaz, and its color is not as rich as imperial topaz. The best color is lemon golden yellow. The brighter the color, the higher the value. If the color is black or brown, the value will decrease.
Blue topaz Blue topaz is the lowest value among colored topaz, because blue tones are the most common. Except Brazil, Madagascar, Sri Lanka, Russia and other places produce blue topaz with large particles, so its rarity is not high and its value is limited. But it's worth saying that the blue topaz is almost the best in Huang Yushi.
Colorless topaz Colorless topaz used to be used as a substitute for diamonds and was once called "slave diamond". Now it is the raw material of color-changing stone, which is generally used to turn the color into blue topaz. Through artificial irradiation, the white topaz becomes rich blue, which is difficult to identify by conventional methods, so the value is relatively low and it is rarely cut directly.

Where does topaz come from? Brazil's topaz is mainly produced in minas gerais, Brazil, because there are a large area of granite megacrysts, which mainly produce topaz in various colors such as yellow, deep Sydney yellow, pink, blue and colorless, as well as topaz in yellow, deep Sydney yellow, pink, blue and colorless. It was once the largest transparent topaz in the world.
Sri Lanka Sri Lanka is also an important producer of topaz, producing blue, green and colorless topaz. California mainly produces yellow and blue topaz.

Topaz is produced in Xinjiang, Yunnan, Inner Mongolia, Guangdong, Jiangxi and other places in China. The most familiar one is that a large number of colorless topaz is produced within 0/00km of Fiona Fang/Kloc, the ghost town of Karamay, Xinjiang. However, this colorless topaz is irradiated and needs to be left for more than a month before it can be used as a gem.
How topaz is formed Topaz is the product of gas-producing hydrothermal stage, so topaz is mostly produced in veins such as granite, gas-producing hydrothermal dolomite, skarn, alluvial rock and acidic volcanic rock.
