About Us

With 40 years experience in the world of fine jewelry, Nicholas and Christine Kosturos founded Patronik Designs in September of 1978. A first generation jeweler, Nick has earned a B.A. and M.A. in English Literature with a minor in Art. A self-taught jewelry designer, he began silver smithing in 1975 and later studied with the GIA (Gemological Institute of America) earning certificates in diamond grading and gemstone identification. His love affair with jewelry has found him designing one-of-a-kind creations for clients using diamonds and exotic gemstones set in both platinum and gold. He quickly built a reputation for excellence in quality, selection and service.

How We Got Started

“When I started in 1978, I focused on customer service.
