What is the actual name of this rock? I feel like this can't be its scientific description. If you do a search for seiryu stone, all of the links will be related to ADA somehow. Although I don't doubt that ADA is hand selected very nice pieces, I have a hard time believing that they own and guard the only source for this rock. I am wondering if this stuff comes in very large pieces. Any geologists out there? What type of rock is this, and where would you expect to find it?
