In 1979, Jay and Celia Feder founded Jay Feder Jewelers. Their dream of becoming leaders in the diamond industry had begun. Jay and Celia realized they shared a very unique passion for teaching. This gift allowed them to become pioneers in the diamond industry with a transparent approach focused on education. It was extremely important to both of them that their customers felt valued and appreciated. They introduced each and every diamond customer to the 4 C’s of diamond grading and patiently tailored each lesson according to the needs of that particular client. Jay and Celia knew that educating their customers, as well as an emphasis on customer service, would be the bedrock of the company’s success. With this vision, and clearly ahead of his time in 1986, Jay wrote “The Practical Guide to Buying Diamonds.”

Jay Feder Jewelers prides itself in having an extensive inventory, featuring one of Denver’s largest selections of loose diamonds and colored stones, while having the most up-to-date designs. Providing outstanding service and exceeding our customer’s expectations is our daily goal. We are proud to feature world-renowned designers such as Armadani, Coast Diamond, George Sawyer Designs, Steven Kretchmer, Verragio, Spark Creations, and Christian Bauer, just to name a few.

As the business continued to grow, Marc grew. He worked alongside his father for 10 years watching this great company flourish. Marc observed early on how important it was to his father to provide the best quality product, excellent customer service, and superior client education. We founded our New York branch, located in the heart of the Diamond District in 2012. This is a full-scale operation, providing a unique approach in diamond cutting and the wholesale jewelry industry. The custom work that we do always amazes our clients! Our motto is “Give us a design idea and watch us turn your idea into reality. We are the largest custom jeweler in Denver. The custom process is easy, efficient and on time. Having our store in Denver and branch in New York allows us to work in tandem giving us a greater reach in the industry.
