Setagawa-ishi-II, 瀬田川石
This page is part II of Setagawa-ishi.
Setagawa-ishi - Sasa Maguro
This is Setagawa-ishi, Sasa Maguro.
In the case of this stone, hollow patterns by cordierite removed are shallow and they look like bamboo leaf.

If you see closer, they look like recessed, but if you touch them and trace by a finger, it is very slightly.
I would like to compare Setagawa-ishi with Shonaigawa-ishi. Shonaigawa-ishi is considered as very similar stones with Setagawa-ishi.
Shonaigawa and Setagawa are distant about 100km.
Shonaigawa-ishi and Setagawa-ishi
Left side is Shonaigawa-ishi and Right is Setagawa-ishi.
Judging from appearances, both stones are similar but looking carefully, Setagawa-ishi is more black and solid.
Setagawa-sihi seems to be changed more than Shonaigawa-sihi in constitution or structure or composition by metamorphism. Surface of Setagawa-ishi is smoother than Shonaigawa-ishi.

Rough surface can be seen.
That is comparison result between Shonaigawa-ishi and Setagawa-ishi. It is just simple comparison as one example.
Of course, there may be Shonaigawa-ishi harder and tighter than Setagawa-ishi. But from my experience of searching stones in Shonaigawa, Shonaigawa-ishi seem to be more rough and Setagawa-ishi could be considered as a king of Suiseki.
Setagawa-ishi - Nashiji
This is Setagawa-ishi, Nashiji. Its shape is Abstractive and looks like a cormorant looking up at the sky.
This stone is also hard and tight.
This is closeup picture. Dots look like surface of pears and therefore, called Nashiji.
Another surface.
Look closely, something black is not removed off but come out. It may be pseudomorph of cordierite but looks like just black hornfels.
This surface may look like more pears.
