Here are four different views of H.H. the XVIth Karmapa wearing the Black Crown. The first (black and white) image was taken in Tibet. It is plain this is not the same black crown he is wearing in the three photographs that follow.
When I attended the Black Crown ceremony, it was with the understanding that merely to see the Karmapa wearing the Black Crown would be sufficient to confer liberation at the time of death. I had the rare opportunity to examine the crown closely, and I do believe it is true: the crown is made from dakini hair.
