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.
Best Jewelry Prices!
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.
Best Trade-In Policy!
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.
