And Jenny Slate slayed in Gismondi 1754! The actress and writer served old-school Hollywood glamour in a sleek Abbraccio diamonds and emerald set from Gismondi 1754. The Abbraccio necklace was built around a single, perfectly proportioned pear-shaped emerald over 22 cts. from Zambia, acquired by Massimo Gismondi in April 2022.
