Agates, jaspers, quartz and many other rocks can be processed in a tumbler to produce rounded gemstones with a very high polish. Most rough is photographed wet to show full color and to give the buyer some idea of what the finished polished stones might look like. |

Apache Tears:
Apache tears are translucent obsidian nodules that can be polished to a brilliant sheen. They are a challenge to polish because they tend to bruise in a rotary tumbler. This can be prevented by using a generous amount of plastic or ceramic pellets as cushioning (click the "more information link below for details) Pieces range from 1/4" (6 mm) to 1 1/2" (38 mm) in diameter.
