Bruneau Jasper is sometimes referred to as a porcelain jasper because the semi precious gemstone cabochons have such a nice porcelain-like finish.
The Bruneau Jasper flow is the most silica-rich rhyolite flow in the area and is predominantly red and brown jasper.
The deposit covers several 100 meters and is mostly covered with unpatented claims. These claims were first filed in the 1950's. But the BLM has closed the area off because it overlooks the river.
Tradition in the Bruneau area claims that the name Bruneau was either from its French translation of ‘brown water’ or after a French explorer by the name of Jean-Baptiste Bruneau.
Bruneau Jasper has a hardness of about 7 on the Moh's scale.
Bruneau Jasper, like all Picture Jaspers, is said to help bring balance to your life.
