If you are being objective, you can’t really explain the price of gold by looking at its uses. Sure it looks good in jewellery but most of the gold doesn’t end up in jewellery, it sits in locked vaults gathering dust. There is now enough stored gold above ground to keep the jewellery market supplied for hundreds of years without needing to mine any more. So logically the price should crash and nobody should bother mining it any more. In fact people predict this all the time but it never happens.
