How do you distinguish between chalcedony and topaz?
In the jade market, the variety of varieties is very confusing, like the chalcedony. If you understand it from the name alone, many consumers may think that the chalcedony is the essence of jade, which is the essence of topaz. The marrow and topaz are two different species, and they can't be confused. So what is the difference between them? How do we distinguish between topaz and chalcedony? The following is a small series of China Jewelry Merchants Network Xiaobian to tell you the difference between topaz and chalcedony.
1, from the color to distinguish
Although both chalcedony and topaz are yellow, they are also different in yellow. The color of topaz has many classifications, such as egg yolk, beeswax, sweet-scented osmanthus, chestnut yellow, etc., and the yellow color of topaz is from light yellow to deep yellow, and the different shades of yellow also determine its different value. The chalcedony does not have so much color, and it is usually called chalcedony, which is orange-red. So from the point of view of color, there are obvious differences between the two.
2, from the composition to distinguish
When chalcedony and topaz appear in people's field of vision, most people confuse them. In fact, the two are not only different in color, but even the ingredients are different. Topaz is a fluorine-containing aluminosilicate mineral, which is often produced in the pores of granite and rhyolite. It is formed when these rocks are heated by steam. It is often called citrine, and its main mineral component is tremolite. The topaz is a kind of quartz, and the main component is silica, so it can be seen that there is a big difference in composition between the two.
3. Distinguish from value
Although the value of topaz is not comparable to that of sheep fat jade, but with the hot market of jade, the development of topaz has been improved, and the sales price in the market has been rising. However, compared to the chalcedony, the price is not very high, and it is affected by the value of the entire chalcedony. The market of the chalcedony is developing slowly, so the value is also one of the distinguishing points between the topaz and the chalcedony.
The above three points are the main difference between the chalcedony and the topaz. Of course, the difference is not limited to the above. The effective method is to compare the topaz with the chalcedony. In the jade market, there are too many similar varieties, and the true and false situation is also very rampant, so you have to be cautious if you want to buy a gem that you are satisfied with.
