暂无分享,去创建一个
A new opal deposit has been recently discovered in the Welo province of Ethiopia. Unlike the opals previously found in the Shewa province, the new material is essentially white body color, resembling Australian opals. Also, in this new find, opal does not appear to form nodules. Otherwise, all its properties are consistent with volcanic opal-CT, as other Ethiopian opals.
