Tadamigawa-ishi-I, 只見川石

Some people say Tadamigawa-ishi and KamuiCotan-seki are similar but of course, both stones are different.

Black and green colors with a gloss and dense surface are actually similar.

When taking it in my hand, Tadamigawa-ishi feels me harder sense than KamuiCotan-seki. When snapping by nail, the high pitch sound is almost metal.

KamuiCotan-seki is 5.5 in Mohs' scale of hardness. From my point of view, KamuiCoan has both hardness and viscous. On the other hand, Tadamigawa-ishi is more hard without viscous.

White silica inclusion is also one of features of Tadamigawa-ishi.

It is difficult to distinguish between Tadamigawa-ishi and Inagawa-ishi because Tadamigawa and Inagawa are connected. Sometimes as Kasugawa-ishi is called as Ibigawa-ishi, Inagawa-ishi is called as Tadamigawa-ishi.
