Fast forward to today, we're in our 4th generation of working with our friends, family, grandparents, parents, and now children. We have fostered and developed an excellent reputation for honesty, integrity, and the finest customer service in the industry, for which are truly proud and thankful.

Our goal is to provide the finest jewelry, custom designed to your specifications, and at the most competitive prices. We have one of the largest selections of GIA-certified diamonds in the Chicago area, and our staff is well-trained to answer all of your questions.
