Yellow Green Jasper — Yakima River Canyon — The Bold Contrast
This material was a rare find even for the canyon. Yellow, green, gray, and black all in one tiny piece of rough — 2x2x1.5 inches with zero room for error. Janyce and I had to fight for every millimeter to keep all four colors in the finished stone.
We pulled this from the Yakima River Canyon. Fifteen-million-year-old volcanic jasper, dense and stubborn at 7.5 Mohs. When it finally polished out, we had something we weren't quite sure what to do with. The Yakima Canyon Collection →
We had bought a 13-pack of random Chinese zinc/nickel pendant backs to experiment with settings. See The Nickel Back Collection → We tried the stone in each one. The Victorian filigree scrollwork back — the fanciest one in the pack — fit it perfectly. We looked at each other and that was that. Sometimes it just lands right.
