Diamond Young's Modolus Property confusion

Hi Comsol Community,

the Young's modulus property of diamond in the Comsol material library is

105 x 10^9 Pascal

whereas the proper property value in literature is an order of magnitude larger:

1220 x 10^9 Pascal - www.chm.bris.ac.uk/motm/diamond/diamprop.htm

1220 x 10^9 Pascal - www.sciencedirect.com/science/article/pii/0925963593902506

1220 x 10^9 Pascal - en.wikipedia.org/wiki/Young%27s_modulus#cite_note-27

I understand that this number can vary for different crystal orientations, quality, etc. but I found no data justifying the big discrepancy of the Comsol value with other values found.

Any idea why that is?

Cheers,

Erik
