America's Coolest Stores in 2016!

Building a Jewelry Superstore is no easy task. It has taken the Yeko’s 40 years of daily commitment to bring the business to today’s level of success. Born and raised in Wisconsin, the Yeko family is proud to have established The Diamond Center in 1982, a world-class store with two jewelry store locations to better serve you in Janesville, WI and Madison, WI.

Although very bridal-focused, The Diamond Center is a full-service jewelry store offering fine jewelry and watches from many top jewelry designers worldwide. Family owned and operated, The Diamond Center rates in the top 1% of jewelry stores nationwide and has joined the ranks of “America’s Coolest Stores” in 2016. Whether you’re looking to create your dream engagement ring, choose from our hand-selected diamond inventory, or shop one of our exclusive designer collections, we have exactly what you need.

The Diamond Center – Where Wisconsin Gets Engaged!

The Diamond Center believes strongly in supporting the local community. The Yeko family and their 30 employees continue to support many local organizations and charitable events. In turn, when shopping at a locally-owned business, customers contribute to the local economy as well. Taxes paid in our county support local resources such as schools, parks, police, and more. It’s a win-win for everyone.

“We don’t take our customers for granted,” says Steve Yeko, Sr. “As my son, Steve Jr. and I work with our customers, we listen to their requests. Our customers deserve the best quality and service at the best price. I know that’s what has made us leaders in the jewelry business in Wisconsin. Others in the industry have tried to mirror our approach, but when you’re as passionate as we are about our customers, products, service and our communities, it’s hard to duplicate.”

9,000 sq. ft. Jewelry Store in Janesville

Designed by Angus Young Associates in Janesville, the new ground-up 9,000 sq. ft. retail center located adjacent to the heavily traveled Milton Avenue retail corridor in Janesville, Wisconsin broke ground in 2015. The Diamond Center – Janesville jewelry store occupies 5,896 sq. ft. on the first floor and 3,000 sq. ft. on a second floor that overlooks their grand sales floor. The building is also home to Chipotle Mexican Grill (2,284 sq. ft.) and Suite 100 Salon Studios (800 sq. ft.). The design of the building was driven by two main factors. We wanted to maximize the amount of natural light reaching our sales floor, as it is the best light for showcasing our jewelry. In addition, we wanted a prominent entry that would advertise our name-brand and exemplify the sense of arrival to our store. The project stressed a high level of structural design with high ceilings and wide open unobstructed views on the sales floor. The end result was a delicate and volumetric space that represents a reflection of the jewelry showcased within.

Steve Jr. meets with vendors from around the world. They often comment that they have never seen a jewelry store of this size and selection anywhere! “The need to offer the best of everything is what my father and I believe in. This is truly what sets us apart from our competition and places us in the top 1% of all jewelry stores in the world”.

When people think of diamonds, bridal jewelry, colored gemstone jewelry, watches and giftware, The Diamond Center is at the top of everyone’s list.
