Dear Sir, Reading in your blog give me a little hope that here I may ask my question to jade expert. Since here, in my country, is very difficult to find a real gemologist, especially who have a broad knowledge about jade. In this opportunity I would like to ask you about my doubtness toward the bangles I have bought several weeks ago from jade supplier. I bought two bangles which I myself did not certain of. Silly wasn’t it? The price was expensive enough for me. Would you please help me to identify whether these bangles are jade or just another stones. I will attach the pictures here. Thank you for your sincere help before. Best regards, Lisa.
Since you mentioned 2 bangles, I presumed that one is the translucent one where you took the picture with the LED torch light behind and the other one is the light green bangle shown by the latter 2 pictures.
The first picture of the bangle shows quite good translucency. From the picture it looks like a bi-colored bangle of rustic brown and light green. There are also some visible veins inside the bangle.
If this is the Type A Jadeite Jade bangle then you have made an excellent purchase (though I am not sure how much you paid for it). Prices of genuine Jadeite Jade is increasing monthly as the mainland Chinese are in a buying frenzy.
From the picture I would think that it is a jadeite jade bangle, but I would not be able to ascertain whether it is the Type A Jadeite Jade or Type B Jadeite Jade.
Try the ‘sound’ test on this bangle. (Read here for more information). A bangle of this translucency will have a very high pitch sound when you knock it with a tweezers or you a small metal ruler. If the sound is just a ‘thud’ it may be impregnated with polymer, in which case, the bangle is just the enhanced common garden variety, which worth is about US$30.00 in any ubiquitous jade markets in every cities in China.
The best solution is perhaps to have it tested at a reputable gemological lab. The best place is in Hong Kong at the Hong Kong Jade & Stone Laboratory in Nathan Rd, Kowloon. In the jade certificate an FTIR (Fournier Transformed Infra-Red) chart is shown where it will indicate the presence or absence of polymer.
For the second bangle, I would say that this is most probably a real jadeite jade bangle. The color is quite even. There are quite plentiful of this variety in the market. I hope that you did not pay a lot of money for this bangle as it is quite abundant. However, a real genuine jadeite jade bangle of medium quality is always better than a polymer impregnated bangle.
If you have more questions I will be happy to assist.
Thank you and have a good day.
