First visit to them was in 2003. I'll be updating my appraisals this month (2008). They were very professional and even appraised some of my minor pieces. They provided a ball-park figure and then asked me if I really wanted to spend the money to get the small ones formally appraised, they didn't just take the pieces and charge for pieces that I wouldn't bother insuring. The appraisals were ready when promised. The appraisals were very detailed and included a picture of each piece. The appraisals were laminated and compiled in a binder. They discount (at least they used to) updated appraisals on pieces they'd already done. I just bought two sets of diamond earrings from e-bay and I'm bringing them here for a reality check. I trust these appraisers. By the way, they used to be called Elliott Gemological Laboratories and were located just a short distance from where they are now.
