Paris Olympics 2024: Is a gold medal actually made of gold?

For Paris Olympics, the medals awarded to winners contain pieces of iron from the Eiffel Tower, specifically the parts preserved from renovation in the 20th century.
 

Each medal includes a hexagon-shaped element made from approximately 18 grams of this iron.
 

The ribbons for the Paris Olympics medals feature a distinctive design, showcasing an illustration of the Eiffel Tower.
 

At the Stockholm Olympics in 1912, gold medals were made of 90% gold and 10% other metals. However, starting from the 1920 Antwerp Olympics, this composition was changed.
 

Since the 1920 Antwerp Olympics, Olympic gold medals have been primarily composed of silver, with only a thin layer of gold plating. 
 

The gold medals from that time onward contain about 92% silver and are coated with approximately 6 grams of gold.
 

Olympic silver medals are composed of 92% silver, with the remaining percentage made up of other metals. Bronze medals are made from a mix of bronze, copper, and zinc.
 

Gold medals were first awarded at the 1904 Olympic Games in Los Angeles. Then, only first-place winners received gold medals, while silver & bronze medals were introduced later.
