This beautiful series of brooches by Lalique were made using clear glass and colorful foils. This one is a beautiful shade of Pink. My research tells me this glass design is referred to as Oiseaux, likely because of the feathery motif. There were 2 sizes made in this line of brooches this is one of the larger sizes. It is signed on the reverse "Lalique" as well as having a square cartouche with further markings.
Materials: Glass, Foil and Gilt Metal.
Measurements: 7 cm long and 11.1mm wide.
Condition: Some wear to the metal, The glass is in excellent condition.
