Jet

Jet is a Dutch feminine given name, functioning as a short form of names ending in the element -jet, most commonly Henriette or Mariëtje, which are themselves Dutch and French diminutive forms of Hendrika and Maria respectively. The name has been in steady use in the Netherlands and carries an informal, affectionate character typical of Dutch pet-name traditions. It coincides in form with the English word for the deep black gemstone or the propulsion system, though these associations are coincidental to its Dutch origin. Related forms include Jette and the full names Henriette and Mariëtje.
