some companies have small steel stamps made with there logo on them. Then you place the stamp on the back or inside of the piece and gently tap in your logo. http://answers.yahoo.com/question/accuse_write?qid=20080503192013AAsGztp&kid=NsAsJTPBVEJpK7K7kmBc&s=comm&date=2008-10-19+20%3A59%3A55&.crumb=

for jewelry...i would say most people dont want brands on them ...but you can put paper tags on the jewelry themselves with your name or whatever on it and people can take them off once they buy them ^_^
