Red emerald, more love. People always have their own preference for colorful jadeite colors, and some people especially like red jade, because its color is bright and dazzling, meaning festive, but the output of red jade is not much, especially the red jadeite with good texture and high color is even less, of course, the price will be higher.
In order to meet the market demand, an optimized treatment method for jadeite has emerged, that is, jadeite "burned red", select some red series jadeite with darker color and lower value, and artificially heat it up to make the iron mineral elements that form jadeite emerald oxidize and dehydrate, showing a more red color.
Technically, burnt red jadeite is artificially optimized, so does it still belong to jadeite a goods, and how should it be described on the appraisal certificate?
Before understanding whether red-hot jadeite is a product, let's first understand what is the identification standard for jadeite a goods in China? It is generally based on the structure, composition, density and reflection spectrum of jadeite and other data for comprehensive analysis to determine whether it is natural jadeite, and like pickling, glue injection and dyeing of b goods and c goods jadeite is obviously not up to standard. Moreover, the national standard stipulates that in addition to cutting and polishing, other ways to change the appearance and durability of jade are collectively referred to as optimization treatment.
From the perspective of processing, the use of physical methods to color the red jadeite, after the high temperature of the fire to change the color of the jadeite, and did not destroy the composition, structure, density and other aspects of the jadeite, but can optimize the appearance of the jadeite, and not like the jadeite b goods, c goods after chemical treatment, completely change the internal structure of the jadeite, so from a certain level, it still belongs to the jadeite a goods, and the conclusion of some identification agencies is still jadeite a goods.
However, strictly speaking, there will be a certain difference between red-hot jadeite and natural jadeite, and if you want to buy natural high-quality red jade, it is best to buy it from a regular and reliable merchant.
