Topaz, hence the name Siyi, is yellow jade, of course, there are two meanings here, one is color, the other means variety. At present, in the national standard "jewelry jade name" can be called topaz jade species, only Hetian jade, this and mineralogy in the "topaz" to distinguish it, that refers to topaz, belongs to the gem variety Ha, is not confused? In fact, there are many names for "names", some from the perspective of mineralogy, and some from the jewelry aspect. It doesn't matter if you don't understand, so we will introduce it today from the aspect of jewelry and jade.

So what is Topaz? Why is topaz on the market not recognized by the industry?
Let's look at the definition of topaz in the national standard: refers to the main color of yellow to medium yellow, yellow green, chestnut yellow and other shades of Hetian jade.
"Yellow like steamed chestnut" is the best interpretation of topaz in ancient times, its yellow color is like the yellow of steamed chestnut with broken shells, warm as crisp, golden color. The color of the original topaz is yellow, with wax yellow, chicken fat yellow, okra yellow, maroon yellow, soft luster, generally brown, yellowish black skin.

Topaz on the Hetian jade market generally refers to "yellow mouth material", the main production areas are Ruoqiang, and the end of the land, Russia also has output, yellow in the bluish yellow or yellow-green, its color belongs to the primary color, but the mountain material is brittle, toughness is not as good as the seed material topaz, whether in oil moisture, density and other aspects, the two are very different, in addition to topaz varieties will also be accompanied by sugar color hues. Although Huangkou is defined as topaz in the national standard, the industry is not recognized at present!

In addition to the yellow mouth material and yellow Qin material, Huang Qin actually belongs to the secondary color, the base color is basically in the surface layer of jade, in the natural oxidation environment due to the skin mixed with the color of the chromogenic metal ions that have been oxidized to form a hue, of course, individual seed material will also be through, the formation of full color yellow flesh, to be carefully screened, of course, good Yellow Qin seed material is also more expensive!
Huangqin color is rich and diverse, some colors are bright and bright, some are gray and yellow and dark, this kind of Hetian topaz can not be considered topaz in the industry, if the yellow Qin material is sold as topaz, it is considered to be an act of breaking the rules!

We often say that "things are rare and expensive", in the value of Hetian jade, "one red, two yellow, three mutton fat", topaz is naturally relatively high in value, in addition to its own color pleasing, "imperial color" also means nobility, wealth, therefore, a little "small expensive" is naturally reasonable.
Today's Topaz has disappeared, there are also a small number of players in the circle of mutual circulation, outsiders can only "look at Huang Xing sigh"! If you like topaz and based on not finding the real topaz, in fact, yellow mouth material, yellow qin material can also be selected, but I want to remind everyone here, Hetian jade market yellow qin material a lot of baked color situation, buy huang qin to be cautious to start!
