“Wonderful experience! Christine Miller’s service was impeccable all the way through the process. I love my new ring and the diamond center selection. Will be back for future purchases!!”

“Can’t go wrong at TDC. Best customer service around and a family owned company. The only place I buy watches and jewelry is the Diamond Center.”

“They did a fantastic job on my wife’s wedding ring that had a broken prong. They polished up to like new. Ring looks like it did 15 years ago. Definitely recommend their service people.”

“Purchase a ring for my fiancée from here & worked directly with Nate on the purchase and everything was curated exactly the way I wanted. If you’re considering engagement rings or new jewelry in general please give them a visit, they’ll treat you right!”

“I have been buying jewelry from the Diamond Center for 25+ years and I can’t imagine going anywhere else. You can tell that it is a family run business that treats their employees well when there is very little turnover.”

The Diamond Center has more diamonds on display than any other jewelry store in Wisconsin! We also have the best selection of all your other jewelry needs including watches, gold chains, colored gemstones, and even giftware.

As a locally owned jewelry store, we set the standards for excellence, quality and service. When you’re shopping for gems and diamonds, make sure you compare cut, color, clarity, carat weight and treatments of Gemstones from one store to the next. If you’re comparing exact qualities, The Diamond Center is sure to have the best price. We are so confident in offering the lowest prices, that we’ll give you $100 cash if we are not able to meet or beat our competitor’s price. We call it The Diamond Center’s $100 challenge.

Open any bridal magazine and you will, no doubt, see ads for many of the same jewelry designers that we offer here at The Diamond Center. These designers protect their reputations by working only with select jewelers nationwide. The Diamond Center has the exclusive jewelry designers you would normally need to travel to a larger city to find It’s all right here at The Diamond Center!

Our Jewelry Designers, Craftsmen and on-site Goldsmiths have years of experience in design and development of custom jewelry. The Diamond Center continues to stay on the cutting edge of the jewelry industry.

Why do we call our staff the BEST? Jewelry certification classes through GIA is just the beginning of their training. Since diamonds are graded using the 4Cs (cut, color, clarity, carat weight), our sales staff needs to understand how they all work together. With over 200 years combined experience, our sales staff trains continually so they can pass their knowledge of quality jewelry on to you.

Have any old jewelry you no longer wear or want to upgrade to something bigger? Bring it on in! We do take in jewelry for a trade-in value, and if you purchased a loose diamond, a solitaire diamond earrings/pendant, or a gold chain from us, you can upgrade those items to something bigger and receive full trade-in value. We have been doing business this way for over 40 years. That’s why it is THE BEST TRADE-IN POLICY around.

We offer a large range of services with our in-house goldsmith team! We even offer SAME DAY “EXPRESS” 1-HOUR REPAIR SERVICE, including professional cleaning and eyeglass repair. Our in-house goldsmiths use their extensive experience along with the latest laser technology to give the highest quality and most efficient service available.
