Galanterie, French for gallantry or chivalry. Various small trinkets given in the 18th century by gentlemen to ladies. They were intended to be carried in the pocket or a reticule, kept in a dressing table or displayed in a cabinet.
Included are étuis, snuff bottles, smelling bottles, patch boxes, cachou boxes, carnets de bal, needle-cases, etc. The German term is Galanteriewaren. A modern term in trade jargon for such pieces is 'smallwork'. Such decorative articles are usually classed as Objects of Vertu rather than as jewelry.
