It turned out you can also use the flashlight to see the emerald bracelets and gems lines.  a lot of people went to Shenzhen antique city with a flashlight to illuminating antique and jade, came to a shop selling jade bracelet to see a customer to buying jade, using a flashlight irradiation emerald crazing.
She using strong light, close to the backside of the bracelet, lighting from the back of bracelet, and then slowly turn the bracelet, looked around, and found a cracking in which one half of the split. Said the bracelet has a problem.
Then I use this method looked around the bracelet, it’s very easy to find emerald bracelet cracking. I look at it several times before, did not notice it. Because bracelets has color, yellow and green, but after light, the color is not so obvious, but the cracking is obvious.
Customers say that you can also knocking two jade, the sound crisp is A cargo. But I worry that what if tap out a split, I feel this method is not reliable. In case the seller said that we came up with a tap of crack. after all jade is not strong.
