Petrified Wood with Blue Opal and Native Copper

From an ancient petrified forest in Indonesia, this beguiling piece of petrified wood with blue opal and native copper has resulted from the replacement — over many thousands of years — of the original wood with opaline silica rich in copper and other dissolved minerals. In this case, the high copper content in the opal has produced vibrant hues of blue and green, with golden flecks of native copper providing shimmering contrast to the iridescent background.
