Finding the perfect wedding bands should be exciting, not overwhelming. Here in the Chicago Loop, many stores offer choices, but at M. Martin & Co., we specialize in transforming this significant purchase into a highly personalized and valuable investment. Since 1939, we have been satisfying customers by combining unmatched quality with wholesale pricing, ensuring you receive the absolute best value for your money.

Quality and Value: Our Wholesale Difference
Our commitment to superior value starts with our unique business model. We operate a low-overhead “upstairs” store on Jewelers Row. This allows us to offer wholesale pricing directly to the public. Ultimately, this means you receive better prices and, critically, better diamonds than you might find from companies selling exclusively on the internet.
We understand that value isn’t just a low price; it’s about the quality you receive for that price. Our owner, Stan Perkins, a Graduate Gemologist (GIA), personally selects every diamond we sell. We focus relentlessly on the finest cut and polish, believing these are the most important characteristics for maximum beauty and brilliance. In fact, we inspect many diamonds, but only a very small percentage are even considered for purchase because most diamonds in today’s market are not cut properly. Cutting is the largest determinant in diamond pricing, meaning our commitment to superior proportions translates directly into exceptional value.
Furthermore, for those interested in exploring modern options, we carry GIA certified lab grown diamonds. These offer excellent value, allowing you to get a larger, gem-quality diamond with the same chemical properties, hardness, and sparkle as a natural diamond for a lesser price.
Expert Guidance, Guaranteed
A core part of our value proposition is the expertise we provide. When you visit us, we guarantee that you will meet only with a Graduate Gemologist/designer. This expertise is invaluable because we educate you on how to use the diamond buying system to your advantage, empowering you to make a truly informed decision.
We also mitigate risk by regrading every certified diamond for accuracy. We pride ourselves on offering a professional atmosphere where we respect your needs and budget.
Customer Confidence Spans Generations
Don’t just take our word for it — our customers confirm the value we deliver. We are proud to serve fourth-generation customers, a testament to our consistent service and quality over decades. Customers often highlight our commitment to quality and fairness:
- One customer, Joe E., shared that every penny spent with us on his engagement and wedding bands was “well worth it.”
- Kino M., who needed custom-made rings quickly, praised Stan for being “extremely professional, accommodating… and very knowledgeable,” noting that he “didn’t try to up-sale anything.”
- Kelli M. was equally as thrilled with her wedding bands, calling the entire experience “Super impressive, all around.”
- Manda P. noted that her husband’s diamonds are “absolutely gorgeous and their shine is constant,” confirming the quality of our selection.
Whether you need a custom design — we can reproduce an item from any sketch or restyle your old jewelry — or want to try on one of the over 400 rings and mountings we have in stock, we are your trusted source for wholesale diamond wedding bands in Chicago. Our comprehensive approach — combining GIA expertise, personally selected quality, and wholesale pricing — ensures your significant purchase is a deeply satisfying investment that will be cherished for years to come.
