Does nacre/mother-of-pearl have a greater compressive strength than human bone? Exactly what it says on the tin: as measured in mPa, does nacre/mother-of-pearl have a greater compressive strength (i.e. it can take getting squeezed more before breaking) than human bone? I recognize that it's rather brittle and doesn't do well with shear loading, but that's not the question here.

### Yes.

According to this article, the compressive strength of nacre is $300{-}500\;\mathrm{MPa}$, whereas the compressive strength of human bones ranges up to around $200\;\mathrm{MPa}$.
