In eastern Washington, are areas with white clay in which are common opal chunks. I read that there used to be hot springs that precipitated the opal. That chunk you have almost looks too brittle to be opal, however. My husband just looked at it without seeing what I had replied and immediately said, "That is fractured opal".
So, that is our guess.

Conchoidal fracturing says quartz, looks like it was colred by iron or hematite. Cool color!
