@thisismyglasgow Fun fact. The dark but iridescent rock that Burtons used to front all their stores is know as Larvikite, coming from Larvikite in Norway. This rock type is used for the commemorative stone you show.

As a geology student I was taught to refer to the rock as Burtonite due its ubiquity on Burtons shop across the UK.
To this day I always prefer the name Burtonite.
