Spirit Stone 5 inch Stone Seashell Carved Rock Shell
Beautiful Spirit Stone (aka Yavapai Travertine) from Arizona.
This is called Spirit Stone by the Navajo Native Americans, because they believe history is told in its layers.
This beautiful, hand carved, larger sized pectin or clam seashell is 5 inches long, 4.5 inches wide and 1 inches thick.
It does not stand by itself. Very unusual and pretty!
Travertine is formed near hot springs. When the pressure which forced the water to the surface is released, the water evaporates and the calcium carbonate settles, forming the mineral Aragonite. As water seeps through, the mineral grows stronger and more durable and the rock becomes Travertine.
