Small box of oval shape in agate, frame in pomponne*, from the 19th century.
This box is in good condition.
A note: tiny little bumps and scratches on the frame, dirt and wear of time, see photos.
Alloy developed by two goldsmiths, Turgot and Daumy, installed at the end of the 18th century in the Hôtel de Pomponne, rue de la verrerie in Paris. It is a copper-based metal intended to imitate gold or silver. Louis XVI had granted them a manufacturing privilege in 1785, whereas until that date, any imitation was prohibited.
