Sure.  Early germanium diodes are point-contact devices made using a small
crystal of germanium.

I've not tried it, but I imagine a modern Schottky diode would be a good
replacement.  Some of them have an even lower voltage drop than normal
germanium diodes, so the set would be a little more sensitive.
