In 1947, Robert W. Johnson started a trade shop performing repairs and alterations for the jewelers and department stores in Columbus, Ohio. The stores he serviced weren't equipped to handle the work or simply chose not to handle the repair aspect of the business. Soon, the other jewelers began sending their customers directly to Mr. Johnson for their service needs. He built his business on professional and honest service, and the customers kept coming back. Eventually, Mr. Johnson opened his own store and started selling jewelry to those customers, and the Diamond Cellar was born. With the help of Mr. Johnson's family and a staff of caring professionals, what began as a small trade shop slowly grew into one of the city's finest jewelry stores. Over the next sixty years, the Diamond Cellar would continue to expand, moving to increasingly larger spaces, to become one of the largest independent jewelers in the United States. Today, the Diamond Cellar operates two stores in Columbus. One is located on Sawmill Road on the Northwest side of the city and the other is at Easton Town Center on the Northeast side.

Throughout its history, the Diamond Cellar has remained a true jeweler, with service at the core of the business. Even today, you can see goldsmith benches in both Diamond Cellar locations. The store prides itself on its professional staff of goldsmiths, designers, graduate gemologists and diamond certificate holders who have helped make the Diamond Cellar a world-class jeweler, and one of the most talked about stores in the industry.

Walking into the Diamond Cellar, one can find an assortment of the finest jewelry and watches available in the world today. The Diamond Cellar buyers travel the globe to seek out the best examples, and bring them back at the best possible prices. Because of their background in design and repair, the staff at the Diamond Cellar is uniquely qualified to judge quality, fashion and lasting value in jewelry. They seek out manufacturers who stand behind their products and deal only with the highest quality merchandise.

Even now, in a world of large, multi-national corporations, the Diamond Cellar remains a family-oriented business. A third generation of Johnsons has joined the staff and everyone at the Diamond Cellar is treated like a member of the family. The people at the Diamond Cellar are active members of the community who give back through fundraising and community involvement. The Diamond Cellar concentrates its charitable giving on causes that directly benefit children with life-threatening illnesses. Today, the Diamond Cellar actively supports over forty of these deserving charities.
