Is it useful is there a uv led strip verify the natural emerald？

At present, the jewelry market has several testing method for folk jewelry, Further studies will be needed to see if these method have any value.

Use ultraviolet led strip to verify natural jade is best way.
Now, let’s find out that jade classification for jewelry. The division of the stars into four classes of jade . They were A、B、C & B+C . A is natural jade . B is through artificial filled jadeite.
C is through high pressure and high temperature dyeing jade. B + C goods is both filling and dyeing jade. because natural stone did not produce the reaction of fluorescent reaction, natural jade does not shine under the irradiation of ultraviolet led.

Experts explain: because B cargo jade and B + C cargo jade implants are epoxy resin. They will produce the reaction of fluorescent reaction under the irradiation of ultraviolet led. This is an important theory in identify work. but C cargo jade not filling, just dye, also can’t produce the reaction of fluorescent reaction under the irradiation of ultraviolet led.   so This application is for B cargo jade and B + C cargo jade use only.
