I am not sure that what I have is what you want, but I purchased a pallet of mixed rocks from Lowes last year which consisted of around 50 bags of various stones with "tears/ holes" in them. I used all the paving gravel, pond stone, river stone, pea gravel, marble ...
There were two bags of red Lava Rock that I had no use for. They are still just sitting on my car port. You are welcome to them for free if you want them!
