I have no idea how to place a pic. I just started using this 4 days ago. I believe it's plastic not a real pearl. And I believe it's sterling silver. But I don't know. These were a gift and I'm not into pearls.
If you rub the pearl gently across your front teeth you can tell if they're real. If they are slick feeling then they're fake if they feel gritty then they're real. Good luck!
