Remember: “Jet” Necklace

Wealthy Bostonian Frances Bowdoin Bradlee, most likely in mourning for her father, James Bradlee, who died in 1872, is depicted in a photograph wearing this necklace made of black glass. Such glass, produced in France and what is now Czechoslovakia, was often called French jet for its similarity to true jet, the polished black petrified wood from England.
