If anyone is still looking for a good place to buy a jade bangle, I have bought several jade items, including a bangle, from yingyujade.com, and never been disappointed. The owner there is super sweet too, and will answer all your questions. I have loved jade for a long time, and last year finally wanted to bite the bullet and buy a really nice bangle, and she was the first person I emailed. I received mine over a year ago, and still haven't taken it off. Love it. I also got a pendant and some jade "needles," and all was fabulous.
You have to be so careful buying jade, though. The tests to determine authenticity can be pretty expensive, so it is easier just to find someone you trust to begin with!
I can post a picture in a bit.
Could you post a pic of your bangle? Am curious to see
