Title
smithsonite
Principal Mineral
Size
Miniature; 46mm
Collection
Carr, P. PFC2007.034
Provenance
Stacey, G.
Entry Type
Specimen TSNB504
Description
Nodular intergrowths of modified rhombohedral crystals (to 11 mm) of translucent, pale orange-pink smithsonite overgrowing a sliver of partly oxidised sulphide ore.
The specimen was purchased from Australian collector George Stacey in 2007, but with no record of its earlier provenance.
The specimen has been analysed by EMPA-WDS and LA-ICP-MS as part of a study of the causes of colour in smithsonite (Weall 2023; Southwood et al. 2025). The colour of this specimen is hypothesised to be due to the presence of Co (203 ppm) and Mn (4133 ppm), both of which are at levels expected to influence color (Southwood et al. 2025). Analytical data is presented in Exhibit 2.
