I am having a ring made by Leon Mege - he is finding me a loose diamond and then setting it. I'll need to have the ring shipped to me (I don't live in New York). I'm told that this is commonly done and that insurance can be arranged? My main question is, what do I do when I receive the ring - do I have it appraised right away? Is there anything I should do to ensure I received exactly what I paid for? I am basically buying the ring sight unseen, although photos have been exchanged and I have the GIA certificate etc.
