Two-thirds of the world’s gold is mined in South Africa, according to Lawrence Livermore National Laboratory.
78% of the world’s yearly supply of gold is used in jewelry, according to the AMNH. The rest goes to electronics and dental and medical uses.
Astronaut helmets come equipped with a visor coated with a thin layer of gold. The gold blocks harmful ultraviolet rays from the sun.
The world’s largest gold crystal is the size of a golf ball and comes from Venezuela. The 7.7-ounce (217.78 grams) crystal is worth about $1.5 million.
Earthquakes can create gold: A 2013 study in the journal Nature Geoscience found that during earthquakes, water in faults and fractures vaporizes, leaving gold behind.
Because gold is soft, it is typically mixed with other metals, or alloys, to give it strength. Measured on the karat scale, pure gold is 24 karats.
The word karat derives from the Arabic qirat, or carob bean, according to Merriam-Webster. Gold sellers, to balance their scales, once used carob beans.
Periodic Symbols for precious metals: Gold = AU | Silver = AG | Platinum = PT | Palladium = PD
The first purely gold coins were manufactured in the Asia Minor kingdom of Lydia in 560 B.C., according to the National Mining Association.
Precious metals are weighed in Troy Ounces. A Troy Ounce is the equivalent of 31.1 grams. So one Troy Ounce of gold or silver should weight 31.1 grams.
You can eat gold … if you really want to. Gourmet shops sell edible gold leaf and flakes that add glitter to everything from pastries to vodka to olive oil. Don’t fear for your stomach: The gold isn’t digested and just passes right through, according to Edible Gold, a company that sells gold leaf.
