6. Mest formbar
Duktiliteten til gull er så god at det er mot himmelen. I teorien kan 1 gram gull strekke seg 4,000 meter, og 10 kilo gull kan lage en sirkel rundt jorden.
7. Menneskekroppen inneholder gull
Hos voksne kan gjennomsnittlig 0,2 milligram gull finnes, med halvparten i bein og den andre halvparten i blodet og indre organer. Det vil si at for å samle 1 kilo gull, tar det omtrent 5 millioner mennesker.
8. OL-gull er ikke rent gull
Olympic gold medals don't actually contain much gold. The International Olympic Committee stipulated in 1978 that the gold medal is plated with silver with a purity of 92.5 percent as the main material, and the weight of the gold plated shall not be less than 6 grams.
9. 'Heart of the Ocean' is not a sapphire
The "Heart of the Ocean" in "Titanic" imitates the famous "Hope Diamond" in the history of blue diamonds. Many people think it is a sapphire, but in fact it is a tanzanite.
