I want to order some rocks online and I was unsure what on earth a 1kg rock looks like or a 3kg one etc. and wondered what size rocks I would get. I have been looking on TGM and are there any better places to order rocks online? I understand different rocks will have different density and I'm specifically looking at their blue stone because it's cheap and looks nice to me. Also is it inert (London tap water is bad enough). Thanks for your time and knowledge. Example rocks would be really helpful.
