The Diamond Center has been a family owned and operated business since 1982, with locations in Janesville and Madison Wisconsin. Our philosophy over the years has been to provide quality service at the best price GUARANTEED. This, coupled with the vast selection and best warranty and service programs available, has positioned us as a leader in the industry. When people think of Diamonds, Engagement Rings, Bridal Jewelry, Colored Gemstones, Watches, and more The Diamond Center is at the top of everyone's list. The need to offer the best of everything is what places us in the top 1% of all jewelry stores in the world. The FREE LIFETIME WARRANTY has been the foundation of our commitment to our customers for decades and we continue to build on this as the industry and technologies change. Building a Jewelry Superstore is no easy task. It has taken the Yeko family over 40 years of daily commitment to bring the business to today's level of success. Both owners have worked from the bottom up within the industry and understand the meaning of hard work. That experience has given them appreciation for our customers, which you will see each and every time you come to The Diamond Center. Through hard work and determination, they built The Diamond Center into one of the highest accredited jewelry stores in the nation.
