This is from the perspective of a customer who brought in a piece of jewelry to see how much the store would offer for it.
The piece in question had been professionally appraised by a certified gemologist. It took him almost 30 minutes to complete the appraisal.
I brought the appraisal with me as it showed the clarity and cut of the diamond. The lady who looked at the piece did not even bother to check it out. Neither did she present any credentials as to her qualifications to appraise jewelry. She took a few minutes to evaluate the ring and offered 7.65% of replacement value!! Not all diamonds are created equal, far from it.
Will never recommend this place to anyone and if anything advise against it. Who knows if you are really getting what you pay for.
