Here I show how bismuth crystals can be made at home. Feel free to contact me with questions/comments.

EDIT:

Mystery solved!

The lack of oxide layer is due to the presence of tin. I used to experiment with different alloys of bismuth and tin and I guess when I was melting all the pure bismuth pieces back together a piece of tin got in.

Huge thanks to Jeffery Schwartz from http://amazingrust.com/ for taking his own time to analyze my sample in an Energy Dispersive X-ray Spectroscopy machine, which confirmed the presence of tin!
