I have this to sell on Ebay for my charity (FurniturePlusLtd.). It is a large decorative goblet in amethyst coloured tinted glass, and with a clear base and stem. It is 10.25in (26cm) tall, and the glass is approx. 4mm thick at the rim. It feels heavy for its size, and feels like good quality glassware. Could anyone help with an identification? I would be very grateful.
