Our special British Columbian rocks have been travelling all over the United States lately, and between that and my own tumbling, I felt justified doing a quick rockhound on the weekend.
I went to a new section of beach while the sun was going down. I didn’t find a whole lot this time but did snag a couple of nice Dallasite pieces. More and more, I’m focused on the stones that show intense design and less dead weight in quartz and basalt.
The picture above shows a common Dallasite rock: nice designs in one section, and mostly just a quartz-basalt brecciated look elsewhere. This is not what I would call a High Grade rock, even though the designed section is very nice. Too much of the weight is made up elsewhere.

And here are the tumbled rocks I took out of coarse grind last week:
