OUMNH Number: 974  
Name and quarry location: Quarzo erborizzato dell'Elba, from the island of Elba, Livorno, Tuscany, Italy  
Geological description: Calcarenite with some grey shell fragments and grains of a black mineral, perhaps schorl.  
Comments: This calcareous stone was mis-classified by Corsi as a sandstone. The locality, Elba, has not been confirmed. All the brown on this specimen is a waxy grain filler not present on the unpolished reverse of the stone.  
Further information:

Corsi's classification: Class 14. Quartz and its varieties; Species 4. Aventurine  
Corsi's text: 181.4/ S24.1 erborizzato dell'Elba
