I have this ring that I have been wanting to be checked if this is indeed diamond and sapphire. Where do you think I can have this checked? I already tried to soak this is vinegar and cleaned with various cleaning solutions and it has never changed.
By the way, I am selling this also but I don't have any idea of the price yet.
