Vapor deposited crystal.
This is a small but jewel-like crystal of purest gold. It was created more or less for fun by Ivan Timokhin, using chemical vapor transport. Gold is placed in a sealed ampule with small amount of chlorine. One end of the ampule is heated up to 300C, the other end up to 500C. At the 300C end gold reacts with chlorine to form AuCl3, which travels over to the 500C end where it decomposes back into gold and chlorine. The net effect is to move gold from the cool to the hot end and deposit it slowing into crystal shapes like this. Isn't it wonderful that stuff like this actually works?
