Camrose & Kross is an American jewelry maker best known for the JBK Collection, a licensed line of high-quality costume jewelry reproducing specific, documented pieces worn by Jacqueline Bouvier Kennedy Onassis. The collection was produced primarily in the late 1980s–1990s and features rhinestones and simulated gemstones (often Austrian crystal) set in detailed mountings, with many pieces signed JBK or Camrose & Kross, and originally sold with certificates of authenticity. Today, JBK pieces are sought after by collectors for their intricate design and direct connection to historically photographed jewels worn by Jackie Kennedy.
