The diamonds are all well matched, estimated to be F in color (colorless), and very, very slightly included (VVS) in clarity. They are estimated to weigh .98 cts. This piece can be worn either as a brooch or as a hair barrette. Leave it to the great jeweler Cartier to design a piece that can slide through fabric smoothly and easy to wear in the hair and, because this clip is slightly curved it will hold any thickness of hair. The two pinstems squeeze together and each fit into its holder making the barrettes quite comfortable.
