For comparison, raw surface collected nodules of Sierra Primrose Poppy from around our Hunters Valley ranch. No stream tumbling here of course as they weather from an epidote rich andesite. Whole hillside across from our ranchhouse was full of big boulders containing scattered nodules, mostly in the 4-6 inch range. Problem was, you'd have to break down the entire boulder to extract them and then, you'd mostly fracture them up.....Mel

Mel-
With the exception of pattern and color, that photo is a perfect match of my rough. I break up boulders of basalt/andesite to extract the nodules. They usually end up in the 1-3" range too.
Nice!

The geology in the two areas must be remarkably similar. Are your specimens hematite rich too? The Hunters valley material is often very rich in metallic purple/silver hematite and sometimes contains gold bearing pyrite too. These tumbles show the variety of colors and patterns in the Hunters Valley area......Mel
