About Us

Montana’s Jewelry, Diamond, and Coin Buyer

The Buxton family started off in the jewelry business in 1955 in Hamilton, Montana. Buxton Antiques operated on 1st Street in Hamilton for thirteen years specializing in estate, antique jewelry, antiques, and fine jewelry.  Conner’s great grandfather and grandmother always had a love for fine gems. That love was passed down through our family’s generation and still exists today.

Eight years later the Buxtons opened another store. Jem Shoppe was opened in Missoula, Montana and was managed by Conner’s father, grandfather, grandmother, aunt, and mother. The Buxtons have shown dedication to their family , and that dedication is apparent with the passing down of the family business to the new generation.

A little over a decade after the Jem Shoppe was opened the Buxtons opened a second store in Missoula, becoming the only jewelry company with two locations in Missoula. Jem Shoppe Jewelers & Rare Coins was operated by (Grandpa) C.M. Buxton Jr. C.M. Buxton III (Marlin) still continued running the Jem Shoppe in downtown Missoula.

After serving four years in the United State Marine Corps Conner Buxton got into the family business as well. He grew up in the business and was introduced to the jewelry industry at a very early age. That experience and training Conner received from his grandfather and father molded Conner into an extremely knowledgeable jeweler, gemologist, and appraiser, even at a very young age. He was trained by his father and grandfather who had over 75 combined years of retail jewelry experience. He shadowed his grandfather for hundreds of appraisals and they would spend a lot of time challenging each other on gem identification. Soon after at age twenty-five Conner took over ownership of his grandfather’s store (Jem Shoppe Jewelers & Rare Coins). C.M. Buxton Jr. (Grandpa) passed in September of 2011. He was an inspiration to Conner and his family. Anyone that knew him well would tell you about his love for gemstones and educating people on gemology. He would spend all day educating clients. C.M. Buxton Jr. was one of the kindest and genuinely good people that you could find. He had a long and successful life including flying P-51 Mustangs for the Army Air Corps. After his grandfather passed away Conner renamed the business to honor him – C.M. Buxton Jeweler & Rare Coins.

The SW Higgins location was in the same location for about 13 years. Conner expanded and moved to the “Hip Strip” (across the street from the Missoulian and three doors up from Ciao Mambo).
