The abundance of elements in the Earth's crust is often measured in parts per million (ppm). Of the three precious metals (gold, silver and platinum), gold is the rarest (0.004 ppm), followed by platinum (0.005 ppm) and silver (0.075 ppm). Gold, silver, platinum, and even unusual precious metals such as osmium are all metals (in a chemical sense) and occur naturally. Unstable elements that must be created in a laboratory (usually through the fusion or irradiation of other elements) can never be counted as precious metals.
Gold is the most sought-after precious metal for investments, and the best rated Gold IRA is an excellent way to diversify your portfolio. 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.
Gold can stimulate a subjective personal experience, but it can also be objectified if adopted as an exchange system. The best-known precious metals are, of course, gold and silver, which have become currency and art objects since before recorded history began. 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.
