When embarking on the significant journey of purchasing a diamond, especially for an engagement ring or wedding band, the experience can often feel overwhelming. The Chicago Loop, bustling with options, can make the decision even more daunting. However, at M. Martin & Co. Jewelers, which has served customers since 1939, the process is transformed into a personalized, insightful, and reassuring experience through our dedication to one-on-one diamond consultations. This approach offers unparalleled benefits that online shopping or large retail stores simply cannot match.

Expert Guidance from a GIA Graduate Gemologist
One of the foremost advantages of a personal consultation at M. Martin & Co. is the direct access you receive to a Graduate Gemologist (GIA) and designer. Unlike many other stores, M. Martin & Co. guarantees that you will only meet with a GIA Graduate Gemologist. This expert is Stan Perkins, the owner and president, who holds diplomas in Diamond Grading and Colored Stone Grading and Identification, and is a GIA Accredited Jewelry Professional. This means you’re not just speaking with a salesperson; you’re consulting with a highly qualified expert who personally selects every diamond sold.
This expertise is crucial for several reasons:
- Personal Selection of Quality Diamonds: Stan Perkins personally selects the most beautiful diamonds and gemstones. He rigorously inspects many diamonds, and only a very small percentage that meet the company’s high standards are even considered for purchase, ensuring the finest cut and polish.
- Regrading for Accuracy: All certified diamonds are regraded for accuracy by our expert staff.
- Informed Decision Making: The consultation educates you on how to navigate the diamond buying process to your advantage, empowering you to make a truly informed decision. This guidance helps in understanding vital characteristics, like the “hearts and arrows” faceting pattern that M. Martin & Co. carries.
A Personalized and Trustworthy Experience
A one-on-one consultation fosters an environment of trust and personalization. M. Martin & Co. offers a relaxing, open, and professional atmosphere. Customers like Kino M. highlight Stan’s highly professional, accommodating, and knowledgeable nature. He doesn’t try to upsell, respecting your budget and ideas.
This personalized approach extends to:
- Custom Design Specialization: M. Martin & Co. specializes in custom design and is able to restyle old jewelry into modern pieces. We can also reproduce items from any picture or sketch. This ensures your jewelry truly matches your personality and tastes.
- Extensive Inventory to Try On: For engagement rings and wedding bands, we have over 400 rings and mountings in stock, allowing you to try them on rather than relying on pictures.
- Support for Diverse Customers: Our company is LGBTQ+ friendly, demonstrating a commitment to supporting all communities.
- Generational Trust: Customers like Libby J., Tj B., Paula C., and Jason D. highlight a long-standing family tradition of purchasing jewelry from M. Martin & Co., spanning multiple generations. This speaks volumes about the consistent service and quality over decades.
Unmatched Quality and Wholesale Value
A significant benefit of these consultations is the combination of high quality with wholesale pricing. Because M. Martin & Co. operates a low-overhead “upstairs” store on Jewelers Row, we can offer quality jewelry at wholesale prices, providing better value and better diamonds than those found online. We pride ourselves on ensuring that our diamonds possess maximum beauty and brilliance through careful selection for cut and polish.
Comfort and Efficiency
Our appointment-only model ensures that your consultation is focused and efficient, offering a dedicated time slot for your needs. Customers like Andy S. commend the ease of getting appointments and communication. Our team is also capable of speedy turnarounds for custom-made rings, as noted by Kino M. and Mike G., who received their custom pieces in just a few weeks. Stan even assists with practical aspects like insurance.
For Chicago Loop jewelry buyers, a one-on-one diamond consultation at M. Martin & Co. provides an invaluable service. It offers the expert guidance of a GIA Graduate Gemologist, a highly personalized and trustworthy buying experience, unmatched quality at wholesale prices, and comfort and efficiency.
