Platinum is one of the rarest elements in the world, much rarer than gold. This is why historically the white metal has been more valuable – just think of platinum credit cards which offer greater privileges and prestige than the gold ones. However, the ‘little silver’ has recently been traded at a discount to gold, as one can see in the chart below.
