Re: Need a mineral/rock for a vodka martini!
Coral? It is organic but it is porous. There are petrified corals too. Pillow lava is a heavy basalt and a small chunk of black rock might make for an interesting look. Sadly, it will wear on glass. I would not want to shake it in a drink. Coral would be fine but petrified coral will be as hard as the glass. Risky.
