I can do it all! :) Smiling! I can do this, I have many vintage jewelry books.
What do you have?
You can send two pieces per question, front and back would be great and let me know any marks on the pieces. Sizes also!
I see you are on subscription, and since I am not an employee for just answer, I cannot tell you how the billing works. But, from what my other customers tell me, they can ask so many questions a month depending on what plan you have.
To help you out do this, why don't you take pictures of several say 10 pieces or so, front and back, tell me what is marked with names etc. Tell me sizes. I have a lot of jewelry books and tell you even if they are not marked what they are worth.
I do not mind doing that many for you.!
