Do what you think is right, it's all you can do. Its always a good idea to hold back a little info on the item and make the "owner" fill in the blanks, size, color, karat, design, etc. You might asked what the inscription says, when there's not one, or give a slightly different color for the stone, because the real, owner would will know the details of the item.
I returned a ring to a woman that was the owner, she knew all the details of the ring. She said she had accidently left the ring on a bench in town and lost it. Years later It turned up 20 miles south in a park in another city. She had replaced the ring shortly after losing it.
I asked twice for a picture of her with the returned ring, never got one. Now i wonder if she thought i had found her ring all those years ago on the bench and kept it till now.
....a wise person told me to not be in such a hurry to return a found ring, take a little time to enjoy the find. That's what i will do next time.
