If you’re considering gold for your next piece of fine jewelry or lab diamond engagement ring, you may be curious to know more about this stunning metal. While gold is an incredibly popular precious metal, many consumers don’t know much about it. 

Before you choose jewelry made out of gold, it’s a good idea to read up on some of the top interesting facts about gold. From its origin to its properties and color, we’ve put together some of the most interesting facts about gold. 

Read on to learn 17 fun facts about gold to determine if it’s right for you or your loved one.

1. Gold Comes from Meteorites

Nearly all the world’s gold came from meteorites that bombarded the planet over 200 million years after it formed. Scientists have shown that the Earth’s surface became enriched with precious metals by impacting meteorites. 

The Earth’s crust and mantle contain gold. It was during this last impact event that the gold which we can access in the crust was delivered. Gold is a relatively rare chemical element, making up only 0.0000004% of the Earth’s crust. 

2. Gold Is Malleable

Malleability is a measure of how easily a material can be molded into shapes. The second gold fact you’ll learn today is that gold is the most malleable element. In fact, pure gold is so soft that it can even be molded by hand. A single ounce of gold can be beaten into a 300-square-foot sheet. A sheet of gold can also be made thin enough to be transparent. 

3. Gold Is Alloyed With Other Metals

Because pure gold is too soft to resist prolonged handling, it is usually alloyed with other metals to increase its hardness for use in jewelry, goldware, or coinage. Most gold used in jewelry is alloyed with silver, copper, and a little zinc to produce various shades of yellow gold, or with nickel, copper, and zinc to produce white gold. 

4. Gold Is Yellow

In its pure form, gold is the only metal that is yellow or “golden.” Other metals may develop a yellowish color, but only after they have oxidized or reacted with other chemicals. 

When mixed with alloys, the color of gold changes from yellow to white as the proportion of silver in them increases. More than 70 percent silver results in alloys that are white. Alloys of gold and silver are commonly used to make gold coins and goldware, and alloys with platinum or palladium are more commonly used in jewelry. The content of gold alloys is expressed in 24ths, called karats. For example, a 14 karat gold ring is made of 14 parts gold and 10 parts alloys. 

5. Gold Is Ductile

Gold is extremely ductile, meaning it’s capable of being drawn out into wire or thread without the risk of breaking. In fact, just a single ounce of gold can be stretched into a gold thread 5 miles long! Gold threads can then be used for products like jewelry or manufacturing needs. 

6. Gold Is Nontoxic

Although gold is a heavy, dense metal, it is generally considered nontoxic. Gold metal flakes may be eaten in foods or drinks, although it is a common allergen for some. Because of this, it’s a good idea to understand your allergies before purchasing a piece of gold fine jewelry. 

To determine if you’re allergic to gold, take a piece of gold and rub it on the palm of your hand. If you’re allergic to gold, a dark mark will appear where it came in contact with your skin. For those that are allergic, platinum is a great alternative that is less likely to cause irritation. 

7. Gold Is Pliable

Along with being malleable, gold is also very pliable. The main difference between the two has to do with the degree the shape can be bent. Pliable materials can be bent or flexed. And materials that are malleable can be beaten or hammered into a bowl or basin shape. In fact, gold is so pliable that it can be made into sewing thread—although that would be some pretty expensive sewing thread. 

8. Gold Is Dense

Gold is one of the densest of all metals. Gold weighs 19.3 times as much as other metals, or about 160 pounds per gallon. Its weight is one of the many reasons gold has become so valuable. This is aside from the fact that, in its pure form, gold can be crafted into almost any shape. A gold bar can be turned into earrings, bracelets, rings, and family heirlooms and is used as a reliable conductor in many modern electrical components.

9. Gold Is Rarer than Diamonds

In its elemental form, gold is significantly rarer than diamonds. A one-troy-ounce Gold nugget, 31.1 grams, is rarer to find than a five-carat mined diamond. After all, carbon is one of the most abundant elements on Earth—contrary to what you might have been told—and a diamond is composed almost entirely of carbon. The average concentration of gold in Earth’s crust is ‘very, very low,’ at 4 parts per billion.

10. Gold Is Used in Electronics

Gold has many uses aside from its monetary and symbolic value. Among other applications, it is used in electronics and electrical wiring.  This is because it does not corrode or tarnish, unlike other highly conductive metals like copper and silver. Electronics aren’t made entirely of gold. Instead, the precious metal is used for specific components such as connectors and wires.

11. Gold Is Found All Over the World

Gold has been discovered on every continent on Earth. ‘Alluvial’ gold is found as small yellow grains and flakes, or even small nuggets, on the beds of fast-flowing rivers and streams. 

You’re more likely to find gold deposits on the inside of bends in a river, where the water flows less quickly. As the water slows down, the heavy gold particles fall through the gravel on the riverbed and work their way down through the soil underneath. Eventually, it settles on the riverbed’s clay bottom. 

12. Gold Is Odorless and Tasteless

High-purity gold is odorless and tasteless. This makes sense since gold is unreactive. Metal ions confer flavor and odor to metallic elements and compounds.

13. The Symbol for Gold Is Au

The elemental symbol for gold is Au. This comes from the old Latin name for gold, aurum, which means “shining dawn” or “glow of sunrise.” The word gold comes from the Germanic languages, meaning “yellow.” 

14. Gold Is Not the Most Expensive Metal

Despite being rare, gold is not the most expensive metal. This is likely why it’s one of the most popular wedding themes for fall. The most expensive metals found on Earth are palladium and rhodium. Both metals are much more expensive than gold. That said, the gold price has been known to fluctuate depending on demand. Even so, gold remains more affordable than other metals. 

15. Oceans Contain Gold

Ocean waters contain gold. There are about 20 million tons of precious metal, worth around $771 trillion, in the oceans. There is said to be about one gram of gold for every 100 million metric tons of ocean water in the Atlantic and North Pacific. There is also gold on the seafloor. The ocean, however, is deep, meaning that gold deposits are a mile or two underwater and hard to find.

16. Earthquakes Can Create Gold

Along fault zones deep within Earth’s crust, small cavities filled with fluids rich in dissolved substances such as gold and silicate minerals can expand to as much as 130,000 times their former size during an earthquake.

In these circumstances, pressure drops, driving a process called flash evaporation. When the pressure in the cavity drops, so does the solubility of minerals in the water. Large earthquakes can deposit as much as 0.1 milligrams of gold along each square meter of a fault zone’s surface in just a fraction of a second.

17. Gold Is Virtually Indestructible

Gold is a noble metal and doesn’t react easily, making it virtually indestructible. Gold doesn’t rust, oxidize, or even react to most acids. This is why all of the gold extracted from the earth is melted, re-melted, and used over and over again. This is why noble metal is also considered sustainable jewelry

This is why it’s a good idea to purchase recycled gold as there is no structural damage, is more affordable, and prevents excess gold mining and the mining of other precious metals. 

Is Gold Jewelry Right for You?

When looking to purchase a gold engagement ring or piece of fine jewelry, gold is an amazing and durable precious metal. But because it’s so malleable, gold jewelry is mixed with alloys that make it stronger. If you’re searching for a gold ring, be sure to know how to figure out your ring size before making a purchase! At 12FIFTEEN, we recommend choosing a gold with no more than 18 parts gold (18 karats).
