Has some age to it fine patina the base. Hard to explain but quite hard crystal glass when its flicked more of a metallic ting than a ping and heavy. Very precise central cut pontil. 4 inches tall. Colour is more dense near the rim and the foot is clear. Anyone seen it before or know who made it.
Any help would be appreciated.
Thankyou
