This is a large modern Lalique crystal platter/charger. The moulded geometric design is "cut into" the underside of the plate. We believe the design is called "Cambridge" (or from a collection called Cambridge). If this is correct, the design dates to c1970 and has been retired.
The piece is signed/engraved "Lalique France"
The platter/charger measures 32 cm (12.75") in diameter. The weight is 1460g / 3.2lb. All measurements are approximate.
The platter/charger is in excellent condition. No chips, cracks or even surface wear has been noted.
