It's edible
Gold is 'biologically inert', which means that it can pass through your digestive tract without getting absorbed into your system. Even so, most experts recommend that you don't gulp down the first necklace you see if you have the munchies!

Aurophobia
It might be hard for most to relate to, but some people suffer from the irrational and extreme fear of gold, or sometimes even golden objects - a condition called aurophobia. The very sight or mention of gold can cause nausea, dizziness and panic attacks, among other symptoms.

Gold is the most malleable and ductile of metals. It may be beaten into gold leaf as thin as 4 millionths of an inch. An ounce of gold may be drawn into a wire more than 40 miles long. Gold is a good conductor of electricity, though it is inferior to silver and copper in that respect.
Gold is one of the densest of all metals. It is a good conductor of heat and electricity. It is also soft and the most malleable and ductile of the elements; an ounce (31.1 grams; gold is weighed in troy ounces) can be beaten out to 187 square feet (about 17 square metres) in extremely thin sheets called gold leaf.
Crushing with a Stamp Mill: A stamp mill is a large mechanical device used to crush ore and extract the desired metal, in this case, gold. The mill consists of a large heavy-duty stamp, which is raised and lowered by a camshaft. The stamp crushes the rock into a fine powder, which is then processed to extract the gold.
As the rarest of the platinum group metals, rhodium occurs at roughly 0.000037 parts per million in the Earth's crust, while gold is found at an abundance of around 0.0013 parts per million, according to the Royal Society of Chemistry.
Many human problems arise through the ability of metallic gold to induce allergic contact hypersensitivity. While gold in jewelry can evoke allergic reactions, other metals such as nickel, chromium and copper present in white gold or alloys exhibit more serious clinical problems.
Gold gets its English name from the Germanic word gulþa (meaning gold). The Old English word geolu means yellow. In Latin, gold was called aurum. This is why the chemical symbol for gold is Au.
Therefore, as hypothesized in one model, most of the gold in the Earth's crust and mantle is thought to have been delivered to Earth by asteroid impacts during the Late Heavy Bombardment, about 4 billion years ago.

Gold is rare and difficult to extract. Gold is malleable and can be formed as needed for use in, among others, electronics, dentistry, medical tools, and the defense, aerospace, and automotive industries. Gold is durable and noncorrosive. Gold has visual beauty and magnetic appeal.
