In 2022, L'ECOLE, School of Jewelery Arts in Paris, launched an exhibition of cameos (relief engraving) and Intaglios incised engraving), engraved gemstones that have been treasured in the jewelry world for centuries. This companion book to the exhibition includes archive material, preparatory drawings, photos, paintings, and ten gate-fold pages. A beautiful exploration of miniature art that has been commissioned by emperors, kings, and collectors alike. A book to pore over.
