Robert E Guertin Jewelers is a full service jewelry destination with attention to personalized service for all our customers. After 27 years of repairing and selling jewelry in the Cape Cod mall Bob with his wife Joanne, decided to move his small shop to Merchant Square in Sandwich. Bob wanting to spend more time with his family began looking from Dennis to Sandwich to purchase his own store and be free to set his own hours of business.

The move from the Cape Cod Mall in 2001 was the best thing that ever happened to Bob and his family. As a jeweler, Guertin has carried on the family tradition. His father Emile and Uncle Valmore started Guertin Brothers' Jewelers on Main Street in Hyannis where they invented the Mother's ring, a customized ring featuring children's birthstones.

Historically sailor's returned home from the islands to present their loved ones with romantic shell collages set in cedar boxes. Made from love, they were the most common gifts from the sea. This exquisite art form has endured throughout the years as a token of love and affection. We are delighted to offer this new generation of Sailor's Valentine jewelry as a perfect gift for any meaningful occasion.
This Collection is inspired by Nantucket native, Bob Marks' hand woven baskets. While deployed at sea, sailors would weave intricate baskets to later sell on the mainland or bring home to a loved one. Bring home a piece of history when you purchase one of our many pieces of the Nantucket Collection.

The best jewelry store ever! Joanne is the consummate professional, offers options while being very considerate of budget. The estate jewelry is exceptional with something for every taste. The stone jewelry is beautiful and there is a considerable collection nautical inspired pieces. It is one of my favorite stops, just to see what is new.

Walked in with my friend to pick up her resized ring.

She took a look at the necklace around my neck and noticed I hadn't cleaned it in a very long time. She told me to hand it over...and came back within minutes, necklace in hand, sparkling clean. She then handed my friend and me 2 of their jewelry cleaner kit, one for each of us, for no charge! I don
