The drawings are of vintage designs up to the 1960s.
Hundreds of vintage jewelry sketches will be put on public display for the first time at Sotheby’s London, according to Blouin Art Info. The article says the drawings are “preparatory sketches before items were hand-made by Cartier, Van Cleef & Arpels and famous ‘maisons.’” They also “attest to the skills of often anonymous, unsung artists who crafted the look of the Tutti Frutti and Egyptian-style jewels by Cartier.” The exhibition, called “Masters of Design,” features designs from the last century up to the 1960s and come from a private collection of 3,000 jewelry documents.
