You desecrated the body, and angered the spirit of the deceased.
Meh, I think maybe not so much. Keep in mind that what constitutes "desecration" is incredibly subjective and depends largely on your particular cultural point of view. Human bones have been used as talisman and in religious contexts in a variety of cultures through the centuries. The possibility occurs to me that the person who owned the piece of jewelry, or indeed the bone's original owner, may come from a cultural or religious perspective other than mainstream Western society.
