Not exactly a paperweight

Nearly midnight - emergency Blip needed - find something glass!
The problem with photographs like this is you have no idea how big it is - if I say it is a paperweight you expect it to be heavy enough to hold a pile of papers down. This might hold one sheet - it is just 4cm high and weighs only 57g! The image is etched on the flat front and the rest is multifaceted making it sparkle. A little souvenir bringing back many memories!
