At present, the popular types of Burmese jadeite in the market are divided into the following four categories according to the level of authenticity. A goods are both natural texture and natural color. Identification methods mainly focus on the following three points. (1) Look before you leap. Because of the relationship between mineral resources and exploitation and the specific situation of people's large demand. At present, there are few good Burmese jadeites on the market. In particular, there are few varieties with green color and bright ground color. (2) Generally, varieties such as Mabel Miao, spinach green, scarlet or violet floating flowers are common. (3) Observed by naked eyes under the light, the texture is delicate, the color is soft and the stone lines are obvious; Slight impact, crisp and pleasant voice; Holding it in your hand has a heavy feeling, which is obviously different from other parts of the stone. B, soak the jadeite with black spots, commonly known as "dirty", in strong acid for corrosion, remove "dirty" and "cotton" to increase transparency, and then inject epoxy resin or substitute filler into the microcracks caused by strong acid corrosion with high pressure to fill and reinforce the cracks. (1) The color of B goods was good at first. If you look closely, the color will become evil. If you look at it under a lamp, the color transparency will be weakened. (2) Within two years, B goods gradually lost their luster, were full of cracks and became ugly. This is caused by the strong acid destroying its original quality. (3) The density is reduced and the weight is reduced. Slight impact, low voice, lost the crisp sound of a cargo. C the goods are completely artificially colored. (1) At first glance, the color is not right and evil. (2) Looking closely under the lamp, the color does not naturally exist in jadeite crystals, but is filled in the cracks of minerals, showing a network distribution of colorless roots. (3) Observing with Charles filter, the green color becomes red or colorless. (4) The surface color can be removed by scrubbing with powerful decoloring agent or turned brown. D goods, D goods pretending to be jade ornaments mainly have the following two categories. (1) jade. That is, other jadeites pretend to be jadeites.
