About Us
Coughlin Jewelers began as a small, family-owned company in 1992 under the name American Diamond Importers. We quickly became known for our superb yet affordable jewelry, and soon business was booming! In 2010, we were delighted to give our thriving business its new name, OUR name - Coughlin Jewelers. After over 30 years, we are still proudly serving the Blue Water Area with our main location in downtown St. Clair on South Riverside Ave.
