KJK Jewelry was established in 1984 by designer Katherine J. Kornblau. In the last thirty years, Katherine’s business has moved out of the little red wagon by the beach on Fire Island and into a Madison Avenue showroom in New York City. She is one of the most versatile and respected jewelry designers in the museum store industry today.

Having spent time in Lima, Peru and Guadalajara, Mexico, as well as studying at the École de Louvre in Paris, KJK Jewelry expands on Katherine's lifelong love of global art and culture. Her international education and interests are reflected in her designs, which are popular with museums and art galleries both nationally and internationally.

Every piece is designed by Katherine with meticulous attention to detail, and the vast majority of pieces are made in New York City.
