Does anybody know where I can buy Mother of Pearl suitable for
inlaying wooden boxes?

In person, at rock and gem shows. It's a fraction of the price of the
knifemaker's suppliers, and they're in turn a fraction of the luthiery
suppliers

It's brittle, it's annoying and there's a dust hazard. Better grades
have a more constant thickness and a re bigger and flatter, all of which
makes it easier to work with.

IMHO, do some cow horn inlay work for practice first. The skills are
similar, but it's not so annoying brittle.
