Gold is so heavy that one cubic foot of it weighs half a ton. Gold is six to seven times heavier than other materials that equal its size. Gold can be hammered so thin that sunlight can shine through it. A single ounce of gold can be drawn into a wire 60 miles long. Gold can be hammered into sheets so thin that a pile of them an inch high would contain more than 200,000 separate sheets.
Gold is considered one of the most important metals in jewelry making.
Gold is so soft it is seldom used in its pure form. Jewelry that is marked 10K is made of 10 parts gold, and 14 parts other metals. Gold can be transmitted from platinum by nuclear reaction. But, because of the rarity of platinum, it is far too costly. South Africa is the largest producing gold country in the world today.
