The appearance of jade jewelry can be distinguished by the two actions of “knock” Dan “photograph” by looking at “color, transparency, uniformity, and shape”.
◎Knock this is the selection criteria for jade jade bracelets. Hang the jade jade bracelet in the air and tap the bottom of the jade jade bracelet with a coin. The better the texture of the jade bracelet, the sound will be clear and loud. Some people also It is judged whether the jadeite has been processed by goods B by knocking sound, but this test is not 100% correct to determine whether it is goods B, because the development of processing technology has made the sound of some goods B knocking sound very crisp, if not often listened The sound of the jade bracelet may be misjudged.
◎Use the light of a penlight or flashlight to inspect the flaws in the jadeite. Jadeite is a polycrystalline mineral with complex chemical composition, so it is inevitable that there will be some small cracks or other minerals in it when it is formed. This test is not to find jadeite without any flaws, but to see if there are large cracks that will affect the durability of the jadeite. If it is a naturally formed fine stone vein pattern, as long as it does not affect the permissible range of the appearance, but if it is a crack that crosses more than half of the jadeite or obvious black inclusions, it will have a significant impact on the price of jadeite.
The world’s gem-grade jadeite is mainly produced in Myanmar, and it is also produced in other countries, such as China, Japan, Guatemala, Mexico, and California, Amerika Serikat, but the quantity is not large and the quality is poor.
The so-called gold is priceless and jade is priceless. The difference between jadeite in the above aspects determines the huge difference in its value. Especially when buying precious jade jewelry products, you must identify jade in all directions, and buy jade with great value for money.
