Keris with elephant-headed blade.

Certainly in a situation where it is not exposed to sunlight or artificial lighting and is protected from dust. A small glass of water in the same space would give a measure of added protection.

I would bathe the ivory hilt for one week in linseed oil, the crack may get closed.
