Coughlin Jewelers is a store like no other. Situated on the corner of Downtown St. Clair, Michigan, the "Crystal Freighter" is a ship-shaped full service jewelry store offering breathtaking views of Palmer Park and the St. Clair River.


A visit to our store is not complete without a full tour, beginning at the diamond-filled stern of the ship, through the Treasure Cove area where the little ones can play, complete with a fish tank full of almost 200,000 carats of cut and uncut gemstones, around Harsens Island and Stag Island past the glass-fronted Engine Room where our jewelers do their magic, to the Captain's Lounge where the gents can rest and enjoy a complimentary libation and finally on to the bow of the ship which boasts a vast collection of high quality watches from the likes of Citizen, Seiko, Technomarine, and our newest line, Victorinox Swiss Army.


Please enjoy our website, and should you not find all the information you seek, please call our friendly staff during our open hours at 810.329.6866.


Thank you for visiting and please enjoy!
