The Selection of Stones
Selecting stones is a part of the fun when creating a layout. We
cannot create a well-balanced iwagumi layout if we are focused only
on the shape of stones, however. We must also pay attention to the
size and texture of stones to select appropriate stones for the layout.
You should select a stone appropriately sized to a given
aquarium as a primary (Oyaishi) stone first, and then select other
stones that match the texture of the primary stone, while at the
same time carefully considering the balance of their sizes. When
you select a stone, you should look at the convolutions and
textures of the stone from all angles to find the best viewing side,
and then come up with an arrangement that makes the most of
the best side of the stone.
SHAPES AND SURFACES
The expression of a stone changes depending on its viewing
angle—find its best “face” by turning the stone.
SELECTING STONES THAT ARE WELL BALANCED
The balance of size of the major iwagumi stones, Oyaishi (the
main stone), Fukuseki (the secondary stone), and Soeishi (the
supplementary stone), should be in a 3:2: 1 proportion.
STONES WITH UNIFORM TEXTURE
Stones come in various colors and textures, even among the
same type. It is important to select stones with the same
texture as much as possible.
STONES IN A POOR BALANCE
If stones are too close to each other in size, they will lack a
variation in height, resulting in a poor iwagumi layout. Small
stones fail to create a powerful impression.
STONES IN INCONGRUOUS TEXTURES
If stones with different textures are combined in a layout, the
resulting layout will look unnatural even if they are the same
type of stones.
