You will find the world’s largest collection of American jade (pronounced ‘ha-day’ in Spanish) at this small museum on the 1st floor of the Instituto Nacional de Seguros (INS; National Insurance Institute). The pieces are varied: expect to see display cases cluttered with translucent jade carvings that depict fertility goddesses, shamans, frogs and snakes, as well as some incredible pottery (some of which reflects Maya influences), including a highly unusual ceramic head displaying a row of serrated teeth. The craftsmanship is generally excellent and pieces are in a fine state of conservation.
