Interesting type of suiseki from eBay

[Lars Grimm]

While browsing eBay to see what type of suiseki were available, I came across an interesting 'category' of stone. I copied and pasted some pictures below. These are cut and polished slabs with very interesting mineral deposits. I think they could be quite interesting in some displays but have never seen them used before. Do others have any thoughts or experience? Here is a link to one of them and you can search by similar items.

I sold many of these when I had a store. Wouldn't call the suiseki but they are awesome. These are from China.
