heres the deal, my fiance got me a ring certified through EGL through a family friend who only deals with diamonds as a hobby. He got it at a great deal, she did it at cost for us. I decided to finally get a new ring band through an independent jeweler and had it appraised today. The color is supposed to be F and the independent jeweler said it was L colored. The diamond even without the band was appraised almost $2000 dollars less than my fiancee paid. Any suggestions as to what I should do.
