Just got my ring yesterday. I noticed a crack coming out from under one of the prongs this morning. No cracks when I picked the diamond out. I was only able to see some small inclusions yesterday. I thought I read somewhere that setting the diamond wrong can cuse the prong to fracture the diamond? Any ideas before I go back to the jewler? I have only had it less than 24 hours. I don''t have the certificate with me. i will check that at home.
