At Cannes in 2016, Julia Roberts wore a Chopard necklace with a pear-shaped emerald and a black off-the-shoulder Armani Privé dress, as reported by Åse Anderson in The Jewellery Editor. It is a memorable reference for a pendant with space around it.

Some red-carpet references remain useful long after the event. Angelina Jolie’s 2009 Oscars appearance is one of them: British Vogue documents her pear-shaped emerald drop earrings by Lorraine Schwartz, worn with a black Elie Saab gown.
