Pierre, from my experience, is somewhat of a fraudster/predator. I’m a woman in my 30s who looks quite young. I brought a couple of rings in this week to be looked at. Gold, diamond, and precious stones. At first, he took a look and told me it was all fake. That they weren’t diamonds, and it wasn’t gold. Once he realized I wasn’t just going to pawn off these family heirlooms to him, and that I am a lawyer, he then retracted his analysis (“sorry!”) and determined they WERE diamonds and gold. He tried to gauge my price and when I told him I was first going to multiple people to get it appraised, he advised me NOT to spend any money for a formal appraisal, then offered me $1500 for the ring. I declined, and paid to have a formal appraisal done the next day. The 18k gold, 2.0kt diamond, and 1.5kt sapphire ring was valued at over $8,400.

I had a ring that I no longer needed and decided to sell. I visited 4 different stores that purchase jewelry, and Pierre at the Diamond and Jewelry Exchange gave me 15% more than anyone else offered. He was also a pleasure to deal with, and just a nice honest guy. It is always a good idea to get a few quotes when buying or selling jewelry, and I strongly suggest that you speak to Pierre before selling or buying any jewelry.
