A classic piece from the Puttapa Mine in Australia, now closed. The only minerals we are pretty confident of are the willemite and calcite - there may be much more. The white mineral has been assayed to be willemite with a very high zinc content.
A relatively unknown and obscure zinc deposit in a remote area of the Australian Outback has recently become famous for producing dramatic fluorescent specimens of willemite mixed with several other minerals. These pieces exhibit bright fluorescence, most with 4+ colors, extreme phosphorescence and wild patterns of color.Ex. Albert Everitt Collection
