Comments: This is wood replacement opal. Millions of years ago trees were buried by earth and volcanic ash. Over time silica seeped through the earth and filled in areas where the wood had eroded. The opal is in the shape of tree roots and branches. The miners rub oil onto the pieces for shine. I have wiped it off but a bit remains.
