M. Martin & Co. Jewelers has been satisfying customers since 1939 and specializes in GIA certified diamonds and gemstones.

  • Personal selection of the most beautiful diamonds and gemstones.
  • You meet only with a Graduate Gemologist (GIA) / designer.
  • All certified diamonds regraded for accuracy by our expert staff.
  • Merchandise custom made in our own shops or ordered from the finest manufacturers.
  • Better prices (and, of course, better diamonds) than you will find on the internet.
  • Wholesale pricing to the public.


M. Martin & Co. sells jewelry for the quality-conscious individual at wholesale prices. Every diamond sold is personally selected by Stan Perkins, Owner and Graduate Gemologist. In today’s market, most diamonds are not cut properly, so only a very small percentage of all the diamonds we inspect are even considered for purchase by our company. We carry a wide range of sizes and qualities including some that display the “hearts and arrows” faceting pattern. For engagement ring and wedding band buyers, we have over 400 rings and mountings in stock for you to try on (we do not expect you to buy a piece of jewelry from a picture). We also carry all types of fine jewelry (with the exception of watches) including wedding bands, cultured pearls, bracelets, pendants, earrings, etc. Since we design and manufacture many of our own pieces, we can offer a wide variety of diamond grades and prices for those on a budget.

We specialize in custom design and can restyle your old jewelry into new and modern pieces. We can also reproduce an item from any picture or sketch.


Stan Perkins is President of M. Martin and Co. Jewelers. He holds the title of Graduate Gemologist (GIA) with diplomas in Diamond Grading and Colored Stone Grading and Identification. He is also a GIA Accredited Jewelry Professional.  As owner of one of Chicago’s oldest jewelry companies, he is proud to be serving fourth generation customers. Stan uses his years of experience to select only the finest in quality and value that will be sold at M. Martin and Co.



At M. Martin & Co., I believe in carrying diamonds of the finest cut and polish. These factors are the most important characteristics that a diamond must have if it is to possess maximum beauty and brilliance. Since most diamonds in today’s market are not cut properly, I will inspect many diamonds before I select the ones that meet the high standards of M. Martin & Co. We are one of the only stores on Jewelers Row that can guarantee that you meet ONLY with a GIA Graduate Gemologist. We will educate you on how to use the system to your advantage, so that you can make an informed decision. Some stores are able to advertise low prices because they sell inferior quality jewelry. Since we operate a low-overhead “upstairs” store, we can bring you wholesale prices on quality jewelry. I would like to think that we have been doing things right, since we have been in business since 1939. We hope to see you soon.

I had thought about buying rings to propose but me being me, I let it drag for weeks (er months) and then I realized I only had a few weeks to buy them before we had to leave the county because I wanted to propose abroad. I am not going to lie, I ended going to M Martin because they advertise themselves as LGBTQ+ friendly and I wanted to give back the community I have gotten so much from (otherwise I would not have been in the situation of proposing to my boyfriend). Stan, who runs the business, was extremely professional, accommodating (I only had 2 weeks to get custom-made rings) and very knowledgeable. He didn’t try to up-sale anything and was very respectful with my rather simplistic ideas. Other stores/businesses (I.e. Tiffany’s) would sell you anything just because you can put your money forward, but it doesn’t necessarily mean they care about you or support you and your community; this is not the case with M Martin at all.

I couldn’t have asked for a more perfect diamond engagement ring. I have gotten so many complements on how much it sparkles in every light.

The Owner, Stan Perkins was so helpful and patient as my fiancé chose a beautiful ring that perfectly matches my personality (and my fiancé’s budget). Stan even helped my fiancé get the ring insured before he gave it to me so I didn’t have worry about wearing it right away!

I feel confident that my ring will last for years to come as my diamond is GIA certified and was recommended by Stan who is a Graduate Gemologist.

Thank you M. Martin & Co. We can’t wait to come in and pick out our wedding bands next!

I was referred to Stan at M. Martin and had a great buying experience. I had little knowledge going into my appointment and Stan was very helpful in creating the engagement ring I was looking for and had it delivered in less than a week. Very easy to get appointments and communicate back and forth. Thanks Stan!
