Robin

"Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience."

-- C.S. Lewis

That's some very beautiful opal and quite a wide range of color in the bottom half. Some of its color patches seem to be almost rectangular. Is that actually the case and, if so, is it close enough to call it a harlequin pattern?

Wow. Gem boulder.

Isn't it amazing that 100 years ago miners tossed material that didn't have seams thick enough to cut solids on the mullock heaps?

I guess they found enough "good" rough that they didn't have to waste their time on rough we'd love to have these days. Like yours!

The photo is very true and I see the pattern but have never seen boulder opal considered a harlequin. That is a fresh split with no polish. About 2.5 inches across. Most of the material is more like this.

Broken River Mining spent most of 2021 running mullock (waste rock) thru a wash plant at their newest claim and were doing very well. I have not seen much of that material. They are on their way to Tucson but we are unable to make that trip this year. That is very hard work and you never know what the old timers left behind. They are very lucky there is water on that property.
