Gold is an elementary substance—a pure substance made up of the same elements that can't be broken into two or more different substances.

Is gold a rock metal or mineral?

Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, veins, and alluvial deposits.

Is gold a mineral from Earth?

Where does gold come from? - David Lunney

Is Diamond a mineral?

diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications.

Is a metal a mineral?

Minerals are solid substances that have formed naturally in the Earth. They have a characteristic chemical and physical properties and usually a regular crystal structure. Most rocks that we see today are made of minerals (they are the 'ingredients' in rocks) and both precious metals and gems are subsets of minerals.

Is gold Nugget a mineral?

Most nuggets are between 85 percent and 95 percent pure gold, but the remainder can be one of several kinds of minerals. Nuggets in laterite can be either reddish or black; nuggets in quartz appear cloaked with white. Any nuggets not deemed to be “jewelry-grade” get melted down and sold as pure gold.

Is silver a mineral?

Silver as a Native Element Mineral

When found, it is often associated with quartz, gold, copper, sulfides of other metals, arsenides of other metals, and other silver minerals. Unlike gold, it is rarely found in significant amounts in placer deposits.

Can gold be man made?

As such, no series of chemical reactions can ever create gold. Chemical reactions change the number and shape of the electrons in an atom but leave the nucleus of the atom unchanged. The ancient alchemist dream of creating gold by simply reacting chemicals is therefore impossible.

What are examples of minerals?
