Rosell Minerales

This specimen was classified as prehnite, according to the accompanying label. When in doubt, a Raman analysis was carried out. The results indicated that it was a calcite. But a calcite from the volcanic areas of Puerto Rico... It is a globular aggregate of scalenohedral crystals. An unusual curiosity to complete unusual locations in the collection. It belongs to the collection of Joan Astor, with a handwritten label and another typewritten.
