After doing tons of research and lots of looking, I found a ring I like, but have some questions. It is a solitaire, with a transition round brilliant stone graded by EGL -- USA as I-J, VS2, 3.6 carat. It was graded in the mounting (simple mounting), and the certification does not have certain measurements -- like the crown or pavilion proportions. The depth is 57.7%, table is 52%, polish is good, symmetry is good, fluorescence is faint, measurements 10.09x10.04x5.8mm. I have always heard that the EGL certifications were less stringent. The jeweler wants to sell the ring for $31k which is about 20% less than the EGL appraisal -- is this too much money? Should I trust the certification since it is missing some of the proportions? Are the proportions correct for a transition round brilliant stone? Any expert advice is greatly appreciated for this potential huge purchase.
