11 years of marriage and no diamond. Time has come. I wish it hasn''t because I am so frustrated with this search. NO two diamonds are created equal, right? I was looking at a diamond certified by EGL. 0.70, brilliant round, E, SI1. Dimensions 5.64 - 5.57 X 3.63 mm. It is already set in platinum 6 prong tiffany. My concern is that EGL has value (replacement value) listed as 6000 US$. However, store is selling it for 2999 $. This sounds too good to be true so I am suspecting that either something is wrong with the certificate, or that EGL is not very reliable. How does this sound to you experienced people? (My knowledge is very limited and naturally, I am afraid of rip off) Thanks for any help that you can give.
