Vesuvianite (Var: Cyprine)
This specimen was a gift from Arthur and Harriet Mitteldorf to the Franklin Mineral Museum (No.281). The main crystal is 6cm on edge.
Johannsenite with Axinite-(Mn)
This complex sample shows epitactic overgrowths of Johannsenite on Rhodonite, with Epidote, Barite, Willemite and Calcite, and is 11cm wide. This sample was originally purchased from the Paterson Museum by George Pigeon, passing through the collection of Ewald Gerstmann and Arthur and Harriet Mittledorf before they donated it to the Franklin Mineral Museum (no. 1869).
This first specimen was donated to the Franklin Mineral Museum in 2006 by Earl Verbeek (FMM No. 6393). It is 15cm across. The striations are due to twinning.
This specimen is 13cm wide and was originally in the collection of R.B. Gage, before passing to Robert Linck and being purchased by Steven Phillips, who sold it on to the Franklin Mineral Museum (No. 6424)
This specimen, from one of the quarries in the Franklin area, is around 10cm wide, and is now in the collection of the Harvard University Mineralogical Museum.
These gemmy Willemite crystals are characteristic of the 'Trotter Willemite' and can be cut into gemstones - this one is 7.5cm tall. An even better one was shown in the cabinet from the Natural History Museum of London - see earlier report.
This third specimen (Franklin Mineral Museum No.729) used to be in the collection of Ewald Gerstmann, and is possibly the richest gemmy specimen of Willemite to come from Franklin.
Willemite (Var: Troostite)
Troostite is a manganese-bearing variety of Willemite and forms characteristicly-coloured crystals such as this one, from the Steven Phillips collection.
