Mari Lou's Fine Jewelry was opened in 1979 in South Holland by Mari Lou McCann. The original name was Mari Lou's Gold Gallery. In 1990 Mari Lou opened a second location in Orland Park where it has remained for over 20 years. The South Holland location was eventually closed in 1992 and focus was given to the one location in Orland Park on 159th and La Grange.  Mari Lou's Fine Jewelry expanded their business in 2004 from the "mom & pop" image to a newly designed and much larger facility, hosting exclusive, premier brands like Hearts On Fire and Pandora Jewelry. 

Mari Lou's daughter, Diana, began her career with the company in 1996 with a degree from Illinois State University. Diana assists Mari Lou in all aspects of management and sales. Mari Lou's son, Donald, graduated from Gem City College in 1993 and worked for the company for 14 years. In 2007 his career prospered and dreams came true when he opened his own jewelry and watch store in Breckenridge, Colorado named Matheu's Fine Watches and Jewelry. Together this family, along with their long standing TEAM, have seen phenomenal growth in the last 30 years due to their dedication, hard work, drive, and most of all their passion. The majority of new business each year is from referrals from their many satisfied customers.  Mari Lou's customers remain loyal to her because of her family's honesty and integrity. Jewelry can be purchased anywhere, but trust and confidence is paramount.

Mari Lou's Fine Jewelry is a full service jewelry store providing jewelry and watch repair on the premises. Custom designing and restyling of your old jewelry has always been their specialty and they carry the finest platinum, 14K and 18K jewelry, while keeping quality and value on the forefront.
