Gold is definitely a good investment but jewellery is the worst way to stockpile it. Gold has a "spot" price, which is its price on the open market per ounce. Your objective is to buy it at the lowest possible premium above spot (you cannot get it AT spot price because that's cost/price for the dealer), and jewellery is the worst way to go because it has the highest premiums over spot by far due to the manufacturing process.

Also, 92% is not really all that pure. Jewellery has to be alloyed because gold is actually a very soft metal, but "investment grade" if you want to call it that is fine gold; 99.9% pure. Gold investing (and this is true for silver as well) is all about the ounces. You want as much physical mass of gold as you can get for your money. More is better, simple as that. So look into online bullion dealers were you can buy gold coins like krugerrands, or gold bars in various denominations (typically the bigger the bar, the lower the premium).

Right now, gold is probably slightly over valued, and silver way under valued, but every 30 years or so there is a reckoning and the price of gold jumps up to balance off all the crazy money printing the government does, and I've seen predictions of $15,000 an ounce considered "reasonable medium-long term estimate".

So forget jewellery its just too little gold for your buck look into bullion coins and bars it gets you the most ounces for your money.
