Jade Enterprise in Guatemala

Jadeite crafts and jewelry is now a staple craft industry in Guatemala. In 1975, Mary Lou and Jay Ridinger opened Jades S.A., the first post-conquest jade workshop in the western hemisphere, and began training stone carvers to work with the very dense mineral. She is recognized by such organizations as The Explorers Club and the Marquis Who's Who as the founder of the modern jade business in Guatemala. Notable figures such as President Bill Clinton and actor Robert Redford have visited her business in Antigua Guatemala and commended her work. Jades S.A. is now frequently visited by foreign dignitaries as well as local government officials and houses a sizeable museum wing illustrating the history and timeline of the use of jadeite by the Maya and pre-Maya inhabitants of Central America.
