I hand cut this freeform shape cabochon out of a lovely material that is called Wave Dolomite or Rolling Hills Dolomite. The rough came from Mexico. Polished finish. I made it from a rare and unusual material from Utah called "Wave Dolomite".
See the rest of my work in my DVHdesigns store where I have a wide range of custom cut focal beads and cabochons. I also do custom cutting if there's something special you need, reach out and ask!
