6.5" Polished Green-White Opal Section - Western Australia

This is a cut and polished section of common green opal with small, black dendritic inclusions. This form of common opal comes from a location south of Kalgoorlie in the Eastern Goldfields of Western Australia. The beautiful green coloration is caused by traces of nickel and/or chromium within the mineralization.

This specimen stands easily on its own without the need for a stand.
