Since 1959, Riddle’s Jewelry has been a family owned and operated business and during those years we have expanded to 65 stores in nine Midwest states. At our headquarters located in Rapid City, South Dakota, we operate a thriving factory that produces many of our own jewelry designs and where our diamond cutters create our own signature Noventa diamond. Like you, we believe that producing and buying products made in the USA is still the backbone of our strong country! After fifty-seven years of dedicated service to our customers, our Riddle’s family name has become synonymous with fine jewelry and diamonds. We are committed to providing the very best variety in style and price, including many designer brands.
