OUMNH Number: 753  
Name and quarry location: Diaspro delle Alpi, from the Alps  
Geological description: Green/brown banded jasper; a siliciified limestone or ironstone showing some recognisable tests of microfossils. It is crossed by many slender fractures filled with colourless quartz. Some stylolites and fractures are present. Chlorite inclusions colour the darkest bands.  
Comments: Nos. 751-753 all have bevelled edges, suggesting they came to Corsi from the same source. In microscopic detail this is more like no. 743.
