Best Pawn Gun Shop. Goldmine Gun and Pawn have had the privilege of serving South Florida. Gold dealer, Jewelry Buyer, Diamond dealer, Used Jewelry and Best Watch Store. We here at Goldmine Gun and Pawn have had the privilege of serving South Florida for many years in other locations, but it was time to start our own store. We were honored to take over Martin’s Gun & Pawn location which has been a well known pawn shop in Florida for almost 40 years. #Diamonddealer #UsedJewelry #Gun&Pawn #GunandPawn #GunandPawnShop #pawnforcash #goldminegun&pawn #buyluxurywatches #bestpawnshop
