Robert E. Guertin Jewelers opened the jewelry store in 1972, and since then has grown. Bob and Joanne moved the store to Merchants Square, Sandwich, MA over 15 years ago from the Cape Cod Mall. The main goal for our store is to retain our high quality jewelry and outstanding customer service. We buy gold, silver, platinum and estate jewelry. Whether you are into estate jewelry, traditional or contemporary pieces, we boast a gallery of platinum, 14kt. and 18kt. gold, diamonds and other precious stones. We also have a large selection of sterling silver jewelry. We also do jewelry repair, appraisals and watch repair.
