Well priced, great packaging, beautiful product, friction backs could be better. It comes with a certificate, however it's generic and doesn't list a grading standard. I would also like it if they added the specific region of China that the pearls come from.

Update: After a month one of the pearls fell off the back, I haven't been able to find where it fell out at. The back not securing it properly was the issue. This happened when my wife slept with them on.

Update: Pearl found, I emailed there customer service and they wanted to send me a new pearl to match. Good job.
