As a subject matter expert in the field of precious metals and their relative abundance, I can provide a comprehensive analysis of the rarity of gold and silver. To begin with, let's explore the fundamental characteristics of these two metals and then compare their occurrence on Earth.
Gold and silver are both considered precious metals due to their scarcity, aesthetic appeal, and resistance to corrosion. They have been used for thousands of years for various purposes, from currency to jewelry to industrial applications.
Gold is a dense, soft, malleable, and ductile metal with the symbol Au. It is a transition metal and a group 11 element. Gold has been a valuable and highly sought-after precious metal for coinage, jewelry, and other artifacts since long before the beginning of recorded history. Gold's purity is measured in karats, with 24 karats being pure gold.
Silver, with the symbol Ag, is also a transition metal and a group 11 element, just like gold. It is even more ductile and malleable than gold. Silver has the highest electrical and thermal conductivity of all metals and has the highest reflectivity of all metals. It is used in various industrial applications, including electronics, and of course, it is known for its use in jewelry and coins.
Now, let's delve into the geological occurrence of these metals. Gold is found in its free elemental form in rocks, veins, and alluvial deposits. It also occurs in minerals, but only in trace amounts. The Earth's core contains a significant amount of gold, estimated to be about 1.8 parts per billion, but it is not economically viable to extract it from there.
Silver, on the other hand, is less abundant than gold in the Earth's crust. It is often found in copper, lead, zinc, and gold ores. The abundance of silver in the Earth's crust is estimated to be around 0.07 parts per million (ppm), which is significantly less than the abundance of gold, which is about 0.005 ppm.
When considering extraction and production, gold mining is a significant industry. However, the amount of gold that is mined each year is relatively small compared to other metals. The total amount of gold that has been mined throughout history is estimated to be around 165,000 metric tons.
Silver production is higher than gold production, with a significant portion of the silver mined coming as a byproduct of other base metals, particularly copper. The total amount of silver mined in all of human history is estimated to be around 1.5 million metric tons.
It's important to note that economic viability plays a crucial role in the mining of these metals. While silver is more abundant than gold in the Earth's crust, it is often found in lower concentrations and can be more challenging and expensive to extract.
Now, let's address the statement about platinum and palladium.
Platinum is indeed a rare metal, even rarer than gold and silver, with an estimated concentration in the Earth's crust of about 0.005 ppm, similar to gold but with less economic extraction due to its distribution and the technology required to refine it.
Palladium is also rare and is often found in the same deposits as platinum.
In conclusion, while both gold and silver are rare, gold is considered rarer due to its lower concentration in the Earth's crust and the smaller amounts that are mined annually. However, the concept of rarity is multifaceted and includes not just the abundance in the Earth's crust but also the economic and technological factors that affect extraction and use.

Two much rarer metals often fly under the radar: platinum and its close cousin, palladium. Platinum is much rarer than both gold and silver -- so rare, in fact, that all of the platinum ever mined could fit into your living room.
