In Baidu, I know that this great god told Yuyou more than once that there are three steps to judge a suspected jade object: the first step is jade, the second step is A goods, and the third step is to comprehensively evaluate its value from five aspects: species, water, color, workmanship and shape.

Talk about two colors of jadeite, such as colored Toona sinensis, blue on a white background, three colors, such as Fu Lushou, and five colors, such as Five Blessingg ware. First, it must be jade, and it is A goods, in order to carry out the next evaluation. Don't just plant water first, so how much evaluation is too impetuous and imprecise.

Is this artifact jade? The first thing to pay attention to is "emerald", which is composed of crystals. Emerald is the most basic feature that distinguishes jadeite from others. Whether it is wool (unpolished), soft polished parts or high polished parts, there must be "emerald". What is emerald? Under the light, jade will give off a little reflection, forming a unique visual effect. This is not even jade. Is it meaningful to talk about tricolor and tricolor? It's not jade at all, even ten colors don't have the value of jade.
