Great service! Jim offered higher than two other shops in the same building on some old jewelry i had and was very pleasant. He had a nice selection of jewelry for sale also with unbeatable prices! I only wish we knew about him when my fiance purchased my engagement ring. We will definitely be back here for wedding bands. Thank you Jim!

After my divorce, I had to sell my engagement ring and a friend recommended to go to the Jewelers Building in Boston. I roamed around looking for a store that buys jewelry and ended up with several offers that were drastically different. At Cambridge Jewelry & Watch Buyers, Jim the owner, greeted me with a smile and a handshake. He could sense my nervousness and began telling me about his three daughters.

He then proceeded to give me a brief lesson on diamonds and an offer to buy my diamond. His offer was HIGHER than any of the previous offers in the SAME building. I highly recommend Jim. He is honest, fair, knowledgeable and very kind.

There's not a more honest, straightforward buyer in the Jeweler's building than Jim. Very knowledgeable about diamonds and high grade watches. I never felt pressured at all when working with Jim, which happens all too often when high value items are changing hands. Thank you!

Since the holidays were over, i decided to do a clean up in my house. Once i was done i noticed that i had a fairly small amount of broken jewelry and unmatched earrings from the past. After putting it in my trusty zip lock bag, i headed into the jeweler's building, knowing i was going fo get best price in there. I went to 4 jewelers before stumbling into a little shop on the 4th floor, cambridge jewelers.

Not only did i think the jeweler was super sweet and honest to me but he gave me a quote $150 more than the highest quote from the rest. Now i know, don't waste time and go directly here. Thank you, I'm so happy. Honestly that's an extra $ in my pocket to use in my spring vaca!
