The two guys that work there have always been more than helpful and always right upfront with me about whatever there buying or not going to buy from me. I never go anywhere else.— Johanna Cooley, Feb 2024

The guy that helped my husband was nice and fair with his offer— John Cook, Jun 2025
I have known Mark and Jamie Dube for more than 20 years and I sell real estate out of their brokerage so I get to see them running their jewelry business and they are extremely friendly, professional, and ethical. On numerous occasions I've seen people bring in items to pawn or to sell and I have always admired how they take a few minutes to talk with the person to make sure that there is something that they really want to do if it's something that has sentimental or monetary value for the family. They have quite the selection of jewelry and it's an easy place to find.— Christopher Olsen, Aug 2022
I am 42 year old and have been like others to thousands of different commerce shops, Mike, the half owner with hus brother is the real deal. I walked away happy, but also with a friend. Whatever your home buying or precious metals and jewlery needs are, you would be foolish not to go here. Truly a great guy.— Ryan Gagnon, Jul 2025
