Excellent use of the rough. I think that rough would make interesting beads.Lots of unused common opal all over the west.

Yes, all of this is from Central Nevada, which has an abundance of common opal in various colors. Here are some examples:

The purple common opal is the rarest in Washington. Excellent clear yellow on the fed land around virgin valley.Years ago before reclamation a diatomaceous earth pit in eastern Washington had a vertical wall of rainbow colored common opal that was 20 feet tall.You had to breal it out of the wall and it was so brittle that it would fly all over when you hit it. It is buried under an apple orchard today.

Years ago when I lived in Nampa, ID, I went on a collecting trip to an area that's near the present Willow Creek Jasper location.  A big power line construction project had just been completed and the bulldozers had unearthed huge boulders, some the size of VW bugs, of both blue and pink lapidary grade common opal.  I collected a bit but not nearly as much as I should have.

Twenty years later, when I lived in Boise for a time, I tried to relocate the spot, but the landscape had changed with much new development, and my memory of the original spot was a bit hazy.  No cigar.  But it is (or was) there someplace.
