The emerald jingle is: red and yellow are princesses, green is emerald, and purple is expensive. The names of emeralds are complex and diverse, and ten words are often used to evaluate them in jewelry industry, which can be called the cross formula.

"Red and green, purple and precious, yellow and reverence. Purple jade itself has a noble atmosphere, romantic and mysterious feeling, which makes people full of infinite reverie. It is not only sought after by oriental women, but also favored by western women.

This is the ancient color grading system in China. Yellow is the noblest color, followed by purple, and green is turquoise, which is a fresh and natural color. This color grading system is embodied in ancient costumes, buildings, utensils and so on.

Then the grade of jade color is very clear. Green is the most important, purple is the rarest, red is the most expensive, then yellow, black and white are available for collection, and the latter three are only suitable for appreciation but not for collection.

Second, look at the color. As the saying goes, purple is precious, green is noble, and red and yellow are auspicious. The jadeite value of these colors will rise sharply, but even a certain color, such as green, has different greens, such as green, sun green and apple green, and their values vary greatly.

The red color of jadeite symbolizes love and heat, most of which tend to be yellow-red or brownish-red, and a few are bright red and blood red, which often plays the role of finishing touch in jewelry. If you can be with green at the same time, the effect will be greatly improved and the value will be particularly precious.
