The reason gold and silver prices vary widely boils down to one simple fact: rarity. The less supply there is of a metal, the higher the price. Therefore, gold prices tend to be much higher than silver prices because it is much harder to get. The reason supply is much larger for silver is because it is an easier metal to mine and it is often mined as a by-product to other metals mining. The average occurrence of gold in igneous rock is 0.004 parts per million. Silver shows up at a rate of 0.07 parts per million.
