Diamonds on Main Owner JoAnn Grundhauser

Owner JoAnn Grundhauser has been at the helm since opening in 1985.  Her career in the jewelry industry began in 1974.  During college, where she received her Bachelor of Science degree in Language Arts, she worked part time at a catalog showroom in the jewelry department.  After graduation, she began a teaching career in high school English.  To supplement her teacher's salary, she continued in her part time job in the jewelry department.  It was there that she was scouted by one of the partners of Unique Keepsake Diamonds, a multi-store operation, to join their team.  JoAnn became the manager of the Maplewood Mall location, where she worked for 8 years until leaving to open Diamonds on Main.

In 1985 Diamonds on Main opened in Downtown Stillwater on the corner of Chestnut and Main, in a storefront location less than 500 square feet.  In 2005, the store relocated to the Valley Ridge Mall between Greeley Street and Washington Avenue.  Shopping at Diamonds on Main has always been a very personal experience offering exceptional values with outstanding quality and a unique buying experience.

JoAnn has completed the Gemological Institute of America's hands on Diamond Grading, Colored Stone Identification, Colored Stone Grading, Pearls, Synthetic Diamond Identification, and Counter Sketching Labs. And, she continues to seek further education opportunities through GIA in conjunction with the Independent Jewelers Organization.
