Gold is rare. Gold is also more valuable than silver because it is available in much smaller quantities than silver. It is estimated that all the gold that has been mined throughout history and that has not yet been mined can fit in just over three Olympic-sized swimming pools totaling 244,000 metric tons. Although silver can be polished and textured in multiple ways to capture light and attention, there is no metal left like gold.
Unlike other elements, gold naturally has a subtle range of unique and beautiful colors. The atoms in gold are actually heavier than in silver and other metals. This attribute causes electrons to move faster, which in turn allows some of the light to be absorbed by gold, a process that Einstein's theory of relativity helped to discern. While gold and silver have similar boom-bust cycles, there are some key differences to consider when deciding whether to invest in gold or, since gold is a much denser metal, people could carry fewer gold coins for the same weight, while their higher intrinsic value also meant that the same weight in gold was worth more than in silver.
Gold can stimulate a subjective personal experience, but it can also be objectified if adopted as an exchange system. While short-term fluctuations in gold prices receive much attention, gold is relatively stable as a long-term investment. Gold is the metal we'll turn to when other forms of currency don't work, which means that gold will always have value in difficult and good times.
