When you are making one of the most important purchases of your life—whether it’s an engagement ring or a bespoke piece—we believe you deserve uncompromising expertise, superior value, and a truly personalized experience. This is what M. Martin & Co. Jewelers has delivered since 1939, and we are proud to now be serving fourth-generation customers. Many of them have shared their 5-star experiences with us on Google and Yelp. Read on to hear what they have to say about us.

Expertise You Can Depend On
What immediately sets us apart is our professional commitment: we guarantee that you will meet only with a Graduate Gemologist (GIA) and designer. Our owner, Stan Perkins, holds a GIA title with diplomas in Diamond Grading and Colored Stone Grading and Identification. This means that world-class expertise guides every interaction. We make sure to educate you on how to use the diamond grading system to your advantage, enabling you to make a completely informed decision.
We only show customers quality stones from top-rated diamond cutters. Since many diamonds available today are not cut properly, we meticulously inspect countless stones, and only a very small percentage that meet our high standards are even considered for purchase. We personally select every diamond we sell, focusing on cut and polish, the factors most important for maximum beauty and brilliance. We even regrade all certified diamonds for accuracy and reject stones if we suspect the grade or certificate is incorrect.
A Reflection of Trust: What Our Customers Say
The quality of our diamonds and the depth of our service are consistently praised by our customers, many of whom become lifelong patrons.
One customer, Laurie DeMoon, highlighted how we go the extra mile, noting that we found a “perfect match to replace it [a lost diamond earring] at a reasonable price and made everything so easy. [Stan] even got me new super reinforced backs so I won’t make the same mistake again.”
Our dedication to honesty and knowledge is crucial, as Max Alper shared after designing an engagement ring: “[Stan] walked us through all the diamond/setting options and recommendations throughout the process and delivered a beautiful ring.” Another customer, Cyle Czerwinski, confirmed they had the “best ring shopping experience” with us, recommending M. Martin & Co. to “anyone who appreciates professionalism, expertise, and authenticity.”
We understand that purchasing custom jewelry can be stressful, especially under time constraints or distance. Luke Bacci, from Dallas, Texas, emphasized that even though he couldn’t travel to Chicago, the process of finding the perfect engagement ring was “incredibly smooth and stress-free”, and the entire process took less than a week. Another customer, Robert Merk, shared that during their consultation for wedding bands, we took the time “to get to know us and our personal style,” making sure they were “completely satisfied.” And when it comes to complex custom pieces, Nicholas Reiter noted that when designing an earring, Stan “was friendly, accommodating, and a pleasure to work with and talk through design ideas” and that the final piece “looks better than I could have imagined.”
Value and Comprehensive Service
We believe superior quality should come with superior value. Since we operate a low-overhead “upstairs” store, we can offer better prices and diamonds than you will find online.
Whether you seek an engagement ring, wedding bands, or to restyle your cherished old jewelry into new and modern pieces, we can help. We keep over 400 rings and mountings in stock so that you can try them on. (Who wants to buy jewelry from a picture?) We furnish an appraisal upon completion of each piece, acceptable for any insurance company. We even work with all major insurance companies for replacement needs, analyzing specifications to ensure adequate compensation for any loss.
Our decades-long reputation, backed by the continuous praise of customers like Siobhan Killeen Toomey—who said, “I can confidently say M. Martin & Co are the best of the best”—is why we remain one of the best jewelry stores in the Chicago Loop.
We look forward to offering you the professionalism and expertise you deserve. Book a free appointment with us today.
