Description
An outstanding specimen of this rarity, probably collected in the late 1970s to very early 1980s. The specimen has sharp crystals to 5 mm, translucent and lustrous, which are of exceptional quality. Significant for both, species and locale, this is also nicely displayable. Initially, because of the sharp crystals and overall quality. Rare material, rarely offered for sale on the mineral market. Ex Erberto Tealdi collection.
