Jacques Bylivelt

Jacques Bylivelt, also known as Giacomo Giovanni Bilivert or Jacopo Biliverti (17 November 1550 – 19 February 1603) was a Dutch goldsmith and jeweler who worked for the Medicis.

He left the Netherlands in 1573 to take a position at the court of Francesco de' Medici in Florence.

He also became head of the gemstone workshop, where he created items for several members of the Medici family.

In addition, he was responsible for making some of the friendship gifts given to French King Henri IV.

His chinoiserie porcelain and jewelry were also ordered by the Roman Emperor Rudolf II and his courtiers, so several examples have been preserved in the collection of the Kunsthistorisches Museum in Vienna.
