This is indeed an emerald A bracelet, so you can wear it with confidence.
It can only be considered as a fine bean seed, which may be close to waxy seeds locally and have a rough texture.
The color is dark, the certificate says it is light green, and the picture should be light oil blue.
The general market transaction price of this kind of bracelet is between 800- 1500, and it is normal within 2000.
The actual price is five or six hundred yuan. You can search related products on Taobao for comparison. Look around and see the quotation. I believe you have a good idea.
I hope you didn't buy anything expensive. If you have any questions, please keep asking questions.
Good luck!
