I contacted Alan Chappron, owner of Gemological Consulting Services, because of the other positive review from judysbook and was not disappointed. I initially emailed Alan from his website to set up an appointment and he responded promptly, just a few hours later. I liked that. Then, Alan appraised my diamond ring while we waited and within one week, had mailed us a nice, 2 page laminated report. The whole experience was great - I highly recommend Alan.
