Recently had a Diamond Unity Ring appraised from AIG Gem Laboratory which is located in Woodland Hills, Caifornia. I wanted to know how accurate their appraisal reports are?

Also would like to know how accurate is the Total Retail Replacement Value of the ring, in the appraisal report below? I was planning to sell it, do you think asking for $2,500 for it is too high
