About Northern Michigan's jewelry store since 1986. The Gold Mine has been Northern Michigan's 'go-to' store when looking for fine quality jewelry at reasonable prices. Yvonne Della-Moretta, a Graduate Gemologist from the Gemological Institute of America (GIA), is the store's creator, designer and driving force. She and her husband Tom have become well-known for going the 'extra mile' for folks looking for unique jewelry not found everywhere. Featuring the famous Mackinac Bridge designs by Evon and hand-made Michigan stone jewelry, the Gold Mine also carries original designs in bridal jewelry, great diamond prices, and can custom-make the piece of your dreams. ​
