Hi everyone... I am a rockhound in Washington State. I collect several unique varieties of Jasper from the Olympic Peninsula. is anyone familiar with the density or...proper steps for grinding and tumbling this type of rock? The orbicular jasper is a different hardness than the agate also found in the area.

Is this the material you're describing? It was sold as Olympic Poppy Jasper and the rough is riddled with fractures, much like most poppy jaspers found along the West Coast. If it's what you have it responds to normal lapidary procedures if you can find a solid piece. It cuts like any other jasper but is slightly softer than the hard porcelain types like Bruneau and Willow Creek.  |

I treat it the same as agate. When tumbling western WA jasper, a lot of it seems to undercut - It is very piece dependent however. When you get a nice piece, it can turn out quite nice. I just posted a picture of a beach find orbicular jasper in the rock tumbling photo area.
