What I have been wondering, are the rocks classed as mini landscape actually the " Seiryu-Seki Stone" from ADA? Also, what are the largest pieces you have? Although I'm only after pieces that are darker, with grooved detail and white veining. (annoyingly specific, I know) It's just I've noticed that some look quite plain and almost as if they've had concrete dappled on the surface. I'm after large pieces around 7-9 inches long and 4-6inches wide. How much would something like this weigh? Thanks.
