I am a landscape gardener and recently ordered some Carbon black limestone for a patio I was Laying at home. I opened the pallet and whilst laying a stone it broke and this is how it looks inside. Can anyone tell me what it is please? It wont stick to a magnet but it is quite hard. Thanks, any ideas appreciated. Trying to upload a picture.
