Description

specimen with many beautiful yellow or orange balls of the uncommon variety "sulfurite" on matrix.

sulfurite is a mixture of metastable allotropes of native sulphur which slowly reverts to crystalline alpha-sulphur.  The composition of the mixture depends on the temperature and age of the liquid when quenched and is usually dominated by long helical chain molecules that are the cause of the plasticity of the sulphur, with about 3 atoms per spiral. Initially elastic, soon gets brittle due to crystallization of the S8 contained in the mixture.

For value the dimension of the crystals I remenber you that the photos of my specimens are taken at only 20/40 enlargement!
