ADA RYUOH STONES have a variety of appearance due to the white line and wrinkles. Their forms are suitable for an iwagumi layout which evokes a reef. For making such layout, an important point is to pay attention to the ridge line and the continuity of stones. It has distinctive characteristics just like ones of the Seiryu Stone, sharp and sheer edges and fair grayish-blue color. You will enjoy the dynamism of the aquascape created with the Ryouh stones. Sold as a box of 20KG. Feel free to call us on 02 9599 8841 if you would like a picture sent for the actual pieces of the rocks.
