Is the blue topaz valuable?

Valuable. It must be pointed out that the color of some popular topaz on the market at present is the result of irradiation and heat treatment. The most common topaz in the market is blue and pink. But more than 99% of them are topaz with colorless or brown rough stones, which are transformed by irradiation and high temperature. Its color is elegant and gorgeous, its properties are stable, and all its characteristics are basically the same as those of natural topaz, which is difficult to identify with naked eyes. Bright pink and blue topaz with natural color are very rare in China at present, and the international price is also very high. The price of irradiated topaz is not high. The price of blue topaz is much lower than that of aquamarine, but the price of topaz is still much higher than that of crystal.

1. Topaz, also known as topaz or topaz in mineralogy, is a fluorine-containing aluminosilicate mineral. Because consumers easily confuse the names of topaz and topaz, the English transliteration name "topaz" is often used in business to label gem-grade topaz. Topaz is very popular because of its high transparency and hard texture, so it has good reflective effect and beautiful color. For example, in the17th century, the Braganza diamond in the Portuguese crown (1640 carat) was once considered as the largest diamond, and now it has been proved to be a colorless topaz.

2. Topaz is mainly distributed in Brazil, Mexico, Saxony, Scotland, Japan, Wula Mountains and other places. Topaz is pure and transparent, but it is often opaque because there are impurities in it. Typical topaz is wine color or light yellow. But it may be white, gray, blue and green. A well-cut colorless topaz may be mistaken for a diamond. Colored topaz may be unstable or discolored by sunlight. Among them, the best dark yellow is the most precious, and the better the color of Huang Yue. Followed by blue, green and red.

3. Topaz is the English name of Topaz, and its name comes from two sources: one is put forward by Pliny, an ancient Roman scholar, who thinks it comes from the Greek word "Topazios" (this is an island name rich in olivine, so it also means "hard to find"), which originally refers to a name called "Topaz" in the Red Sea. Another view is that it originated from Sanskrit "topaz", which means "fire". 1737 A man named Henkel was named after topaz, describing Germany as rich in topaz.
