Here is a diadem made of diamonds from 1904. It was created by Chaumet during its glory years under Joseph Chaumet (who remade the 18th century jewelry house into an international boutique). Chaumet was an artist who looked for inspiration in unexpected sources, so this crown of diamonds is made to look like the stalactites in a cave, dripping with scintillant water. The piece was originally owned by Louis Cesar, Marquis of Lubersac, who was an esteemed senator of the Third Republic. He commissioned the piece for his daughter-in-law. It is so beautiful against a black velvet background, but I wonder if it is annoying to wear!
