1, look at the color
The color of natural jadeite is very natural. The brighter and purer the color, the more evenly distributed the jadeite, and the higher the quality. Some artificially dyed jadeites become very bright in color, but lack aura and look dull and unnatural at all.
2. Listen to the sound
A very simple way to judge the quality of jade is to listen to the sound, tap the jade gently with a gadget and listen attentively. The sound of natural jadeite is crisp. Generally, it is judged as a good jadeite with a crisp and melodious voice, and it is regarded as a bad jadeite with a low mute.
3. Look at transparency
Good jadeite should have good transparency besides pure color. Light can be used to illuminate jadeite. High-quality jadeite has clear interior and few impurities. The more transparent and shiny jadeite is, the better its quality is, and vice versa.
Distribution of jadeite origin:
Most of the high-quality jadeites in the jewelry market come from the Quaternary and Tertiary conglomerate layered jadeite deposits in the Ulu River (River) basin in northern Myanmar. They are mainly distributed in Kachin State in northern Myanmar, with a length of about 240km from north to south and a width of 170km from east to west. 187 1 year, several major mineral deposits were discovered in Lu Wu, Myanmar (also known as Wu Jia, Wulong and Lu Wu), among which four are the most famous.
They are Du Mao, Myanmar Mao, Pan Mao and Nan Nai Mao. Primary jadeite is mainly composed of white jadeite with various green tones, brownish yellow and light purple. In addition to jadeite, there are diopside, amphibole, aegirine and albite, and green jadeite rarely reaches the gem level.
