Huge black metal tiki pendant

I remembered I have this tiki pendant when I saw valentino's post from a while ago: http://www.collectorsweekly.com/stories/89144-salvador-teran-for-marbel-ceramic-on-sil
Mine is not as nice. Its about 10cm! And its really very heavy, even for its lenght. I think its very heavy pot metal or something similar. I think its nothing special but I would like to know: does anybody know when it was made? Thanks a lot!
