Breccia Aventurine — Yakima River Canyon — The Dark Horse
Yakima River Canyon is 17 miles of curvy highway along the river, with pull-off's every mile or so to walk down to the water. First trip in. We pulled this one straight out of the riverbed — not the bar, the bed. The Yakima Story →
You learn to look for three things — contrast, shape, texture. This one had all three. Deep black ground with grey-white veining running through it. Think picture jasper, only at night. I picked it up, turned it over, and it went in the keep pile. The Yakima Canyon Collection →
We got it home and put it on the wheel. It polished out clean. High gloss. The veins went sharp. Not dyed. Not enhanced. One of a kind.
