How Did Gold Become Desired by Ancient Civilizations
Gold is first known to have been acquired by ancient human societies in the 4th millennium BC, a time when copper and metals were beginning to be utilized more frequently. The use of gold expanded during this period because pyrotechnologies improved. As pyrotechnologies improved metals such as gold and copper became more flexible. In fact, when gold appears in the New World, it also appears to be associated with the early development of pyrotechnologies, suggesting gold develops early as metallurgy developed. This likely also means gold, and its luster properties, were desired early on by societies able to master pyrotechnologies to extract and create gold artifacts.
Early Use of Gold
One of the oldest known uses of gold appears to be in Bulgaria, from a site that is called Varna Necropolis or Varna Cemetery, which dates to around 4600 BC. The site is a burial ground were a number of gold artifacts were found to be in burial contexts associated with a variety of individuals. Surprisingly, out of the more than 200 graves found, many of them contained gold and other metal finds (primarily copper; Figure 1). This indicates a society that had already developed a strong affinity toward gold, and it became a status object for many members of society.
However, we also begin to see that not all individuals were treated equally. One individual seemed to have far more gold buried with him, with objects including a gold mace, jewelry, and even a penis sheath made of gold (Figure 2). This could indicate that this society had begun to develop a type of chiefdom society, where one individual did accumulate more power than others and consequently have more gold than the other graves.
In the southern Levant, a cave in Nahal Qanah contained eight artifacts from a burial context that suggests a type of elite burial ground could have been established by the 4th millennium BC. These gold objects were in the form of gold rings. In fact, the find suggests gold could have already become the privy of the most elite in society. 
What the finds at Nahal Qanah and Varna Necropolis show is that early from gold's history it had already become an object that differentiated wealth and status in societies. In fact, we can say that gold seems to be associated with hierarchy, different levels of power, and different access to wealth at its inception of use. Clearly, this relates to the traits of its beauty and rarity, although it is one of the only types of elements we have known that seems to have these cultural attributes true for a large number of societies.
Perhaps, though, there are differences in its view, as seen by these early societies. For instance, the finds in the south Levant showed that gold was even more restricted, suggesting the most elite members of society may have only accessed it. In both Bulgaria and the south Levant cases, gold was found in the form of body jewelry; in the majority of early finds of gold known, in fact, gold was often associated as body adornment, whether for the living or the dead.  This suggests gold, at the very least, was an element intended for display, whether to the living or the dead, and can be considered a type of showing off perhaps, to impress others, the gods, or even spirits.
In Egypt and Mesopotamia, the two main regions where early urban cultures developed, gold was used by the 5th millennium BC. In Egypt, significant mining was likely already taking place in areas where gold deposits were commonly found, mainly in southern Egypt and Nubia. 
In Mesopotamia, the first gold appears in the 5th millennium BC during the Ubaid period. We begin to get references to gold in texts by the 3rd millennium BC, showing it becoming an important object for imports. What early texts also show is that states had a large control of the gold trade, although it was not exclusive to states. Nevertheless, gold became mostly associated with priests/temples and royalty.
Private households also traded gold and often attempted to acquire it as an important long-term holding, but rarely was gold buried by private houses with graves (i.e., it was probably far too valuable for common households to remove this item from their wealth).  Gold, for private households, becomes a way for families to preserve and pass on wealth, given its great value and non-perishable nature.
In many cases, where gold has been discovered, it was found as an alloy with silver (i.e., electrum). At times, gold was also alloyed with lead, indicating that pure gold was generally rarer. In fact, in addition to providing extra strength, alloys also allow the one to utilize more of gold find to create larger objects that look like gold. This gives an appearance of an even larger gold object.
By the early 3rd millennium BC, gold becomes symbolic with royal authority in Egypt. One has to remember the Great Pyramid, and other pyramids, were adorned with gold, in particular, the top part of the pyramid was likely made of gold so that it could shine at a great distance. In part, for Egypt, the shine of gold resembled the sun's shining characteristics, representing the chief god Ra for Egyptians.
To obtain more gold for both domestic consumption and trade, expeditions became organized by the royal authorities for mines containing gold.  In the Indus, by the 3rd millennium BC, and likely earlier, gold was also utilized extensively, reflecting its increased importance for elites and trade. Like other regions, gold was generally found as part of the electrum, which is also a natural alloy. 
In the New World, the Andes region, in Peru specifically, has the earliest dated gold finds, where objects date to around 2000 BC. Interestingly, these early gold finds are in the form of jewelry and found in a burial context, similar to the Old World discoveries.  This could suggest, similar to other regions, that as social hierarchy and stratification became established, gold was one object that differentiated humans' status within society. In other words, gold becomes associated with wealth and power soon after it begins to be used (Figure 3).
Role in Society
In the cases where gold was found at relatively early dates, several characteristics are evident. For one, gold is often found in funerary contexts, suggesting it was both a status symbol in life and something to be taken to the next life. Interestingly, in many of the finds from the Old and New World indicate that gold, despite its rarity, was from its onset a way to display power in the afterlife and as a way to remind others of the power and prestige of the individual to members of society after they had passed away. 
This concept continues when we see the development of state societies. Kingship, and by extension the state, begin to utilize gold more frequently for burials and in many of these cases it was a way to display power in the present and afterlife.
Perhaps this reflects the next life or afterlife similarly is characterized by social stratification. As social hierarchy developed in ancient societies, which seems to be true both in the New and Old Worlds, gold was common among societies that differentiated individuals in power and prestige. So in addition to being evident in the finds from Bulgaria and southern Levant, it is also evident in Egypt, Peru, and Mesopotamia, showing the diversity of cultures where this trait develops.
Nevertheless, there are key differences with how gold was treated in early societies. In the ancient Near East, gold was often found as jewelry with women, suggesting women often wore gold as representing family wealth or were often the ones who literally wore the family's wealth. 
One can consider gold and women's jewelry as a repository of family wealth. This could also be one reason why we find female burials often having large quantities of gold, as not only did they literally carry the gold but the family wealth is best shown off utilizing the female members. For example, the burial of the Queen or Priestess of Puabi from the ancient city of Ur is one example of this (Figure 4).
By the 3rd millennium BC, we begin to see gold having more of a trade value, although very likely this occurred earlier. We see evidence of gold being shipped in from distant regions, such as India or Anatolia, in places such as Mesopotamia. In the 2nd millennium BC, when the trade in gold became more substantial in the eastern Mediterranean region, it is during this active time of trade that gold becomes a standard used to measure value of other commodities. In fact, gold, between 1600-1200 BC or the Late Bronze Age, was becoming the basis of value for many valuable objects now being traded between Central Asia and the Mediterranean, including metals such as tin and copper. 
However, this was a relatively exceptional period, as in most other Bronze Age periods, silver was considered the more common standard, given its greater prevalence. 
Evolution of Gold
During the 1st millennium BC, by around the 6th century BC in the Near East and eastern Mediterranean Hellenistic states, we begin to see coins now utilized with gold. In fact, it is one of the first metals to be fashioned into coins, suggesting gold coins and coins i general were first intended for high value exchange.
While this largely reflects gold’s role as an object utilized for trade and exchange, it now also shows royal authority was beginning to stamp gold with iconography as a way to show government-level backing. This derives from the gold and royalty concept we had seen in the third millennium BC graves and other royal or high elite status. In effect, coinage and gold become established as the privy of the state 
Eventually, as gold coins continue to be utilized, gold and how much gold in coins become standardized more substantially. The concept accelerates in the late 1st millennium BC across the Mediterranean world, where gold is always the top-level currency and can only be minted by the governments controlling a given region. This concept of gold currency continues into the Medieval world, in particular for Europe after the reemergence of states.
Arguably, one of the chief motivations for the Spanish conquests in the New World was gold. Much of that became refashioned into the gold-level currency used by Spain's governing bodies and banks after their conquest. This helped launch Spain and other European powers eventually into a global race for power, but one can argue a race to accrue as much gold as possible, as it symbolized Europe's new power.
The example shows that gold had, very early, established itself as a metal distinct from all other metals. It quickly became a prestige good that changed media, such as in coinage, but the prestige continued irrespective of the media and the modern era.
Gold can be seen to be something of great desire in many societies in the New and Old worlds (the Americas, Asia, and Africa). Despite the diversity of where gold was first found, at the onset, gold was seen as a way to differentiate the power of individuals in this life and the afterlife. This suggests the qualities of gold as being attractive to human societies seem almost universal or innate. Gold utilization in societies evolves as a basis for economies.
By the time currency or coins are used, gold becomes a high level standard that royal authority can only support and uses as a basis in economic exchange by placing the image of the king on currency. This begins to make gold as something to be controlled by state societies and their primary privy rather than that of common individuals. With the control of gold by governments, this begins to help standardize its value, and this concept continues into the modern era. In contrast, gold’s value and importance to society have only increased since ancient periods.
