Corsi 345, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History

OUMNH Number: 345  
Name and quarry location: Alabastro bianco di Collepardo, from Collepardo, Frosinone, Lazio, Italy  
Geological description: Banded compact travertine composed of exceptionally coarse-grained columnar calcite.  
Comments: Collepardo, southeast of Rome, is famous for its karst features and limestone caves containing dramatic speleothems which were first described at the beginning of the 19th century. A rather more orange-coloured variety than Corsi's is illustrated in Faramondi (1985), part of the collection of ornamental and building stones in the Servizio Geologico d'Italia. Although paler in colour than Corsi 344 (alabastro scuro di Collepardo), this stone is certainly not white.

Corsi's classification: Class 1. Marbles; Section 4. Concretionary marbles; Species 1. Alabasters; ii. Italian alabasters
