Corsi 211, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History

OUMNH Number: 211  
Name and quarry location: Verde di Bagnaia, from Bagnaia, island of Elba, Livorno, Tuscany, Italy; or perhaps ribbon jasper from the Ural Mountains, Russia.  
Geological description: Siliceous rock featuring abundant green reduction spots; it may possibly be a metamorphosed burrowed mudstone. The specimen is coated with beeswax.  
Comments: No reference has been found to this stone from Bagnaia, on Elba. It has been noted that it bears more than a passing resemblance to 'ribbon jasper' which at this time was being obtained from various locations in the southern Ural Mountains of Russia (Price, 2007), and was used, according to Giusti, in the pietre dure workshops of Florence.
