I have lots of Seiryu Stones available I am selling these by the pound. I don't have individual pictures of all the stones I am selling them at $3lb shipping is generally $11 for a medium flat rate box. Below are a few example pics of some groups I put together and a few photos from the net as set up examples.
There is 2 yard sticks in the pic for a size reference. These are all very beautiful stones! (US Shipping price, outside the us PM me for a quote)
