At the bottom of this post is an interesting infographic about Gold provided by numbersleuth. So if all the gold in the world would provide 5 rings for every person......what would it be for platinum? And the better question is, since platinum is the most rare of precious metals and actually has industrial uses as well, why is platinum over $200/oz cheaper than it's less rare counterpart?
History says we have an anomaly (although not yet at record levels). Maybe by the time platinum gets it's own infographic the ratio will be a little more normalized.......
