What type of slabs

[geordieboy]

Can anyone please tell me what these slabs are made of? I was wondering if I could contact the manufacturer of these to see it was possible somehow to get the damaged ones to look a little like the original colour photo. I know, its a long shot, but the thought of having to renew 50 sq. mtrs fills me with dread.
Hope these pics come out ok. Please let me know if not.
Thanks in advance

I couldn't tell you the importer or manufacturer, but these are black limestone. It is well know that this product fades regardless of where it has been bought from, it's start jet black and ends up a mid to light grey
