About Exclusively Diamonds


Founder Sally Nelson opened the doors to Exclusively Diamonds in 1980 on the fourth floor of the historic Matt J. Graif office building in downtown Mankato. Prior to this location she had worked from an attaché case on her dining room table selling to family and friends. Over the years Exclusively Diamonds has evolved from Sally employing her two daughters to over 15 employees. Her daughter, Sarah, purchased Exclusively Diamonds in 1998 and moved the store in 2000 to its present hilltop location.
