What are these rainbow diodes

[icecycle66]

I was taking an inventory of all my parts and I found a baggy of these rainbow diodes.
The bag was labeled "GE", so , they are probably germanium.

Does anybody know what these are?

Maybe this will help.

I'm not sure since I am just learning this stuff.
