Corsi Collection of Decorative Stones

view of stone 607

Corsi 607, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History

OUMNH Number: 607  
Name and quarry location: '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.  
Further information:

Corsi's classification: Class 7. Serpentines; ii. Common serpentines  
Corsi's text: 151.32 Serpentina delle Alpi
