Corsi 752, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History

OUMNH Number: 752  
Name and quarry location: 'Diaspro delle Alpi', from the Alps (not confirmed)  
Geological description: Breccia of white granular quartz and other clasts, many rimmed with muscovite, in a red ferruginous quartz matrix. Some fractures are filled with calcareous cemented sandstone. The whole rock is sheared and folded.  
Comments: Despite its superficial appearance, this is not a jasper. Nos. 751-753 all have bevelled edges, suggesting they came to Corsi from the same source.
