For sale is a green yellow specimen of pyromorphite on a brownish mineral which Im not sure what it is, from Broken Hill, NSW. I say plus in the header because there appears to be spinel law twinning in the brownish material, see the third pic upper right hand corner. The specimen features a fine spread of nicely contrasting pyromorphite crystals against the darker mineral, this darker mineral is not the the same as the matrix which is a quartz type matrix.
