Gold is rare throughout the Universe because it's a relatively hefty atom, consisting of 79 protons and 118 neutrons.

Carats and Fineness
For example, 24-carat gold is considered 100% pure, while 18-carat gold is 75% pure (18/24). Fineness is another way of expressing purity, typically measured in parts per thousand. For example, 999 fineness indicates that a piece of gold contains 999 parts pure gold out of 1,000.

This high value can be explained by gold's physical properties and history, plus what can be described as a unique 'Goldilocks' nature. It is scarce, but not too scarce for use as coinage. It has many useful applications, but not too many to be totally consumed by – and governed by – industrial demand.
The unique colour and shine, combined with the fact it doesn't tarnish, gave gold a unique edge over other metals and the rarity installed confidence because people could have faith it would hold its value as the difficulty in mining gold meant no-one could try to devalue the metal as a currency.Gold is a dense metal.
