'Serpentina delle Alpi', from the Alps, or more probably verde dell'Elba from the island of Elba, Livorno, Tuscany, Italy
Geological description:
Ultrabasic rock composed of sprays up to a centimetre long of light green actinolite. These penetrate large dark sprays of amphibole, most probably hornblende.
Comments:
Corsi nos. 583, 607, and 610 all appear to be from the same deposit as samples of unpolished stone in the Museum's early 19th century Daubeny collection, also recorded as from Elba. The name 'verde dell'Elba' is more appropriate because this is clearly not a serpentinite.
