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 Ryuoh stones.
