The special properties of gold make it perfect for making jewelry. These are all properties of an attractive metal that easily turns into beautiful objects. Gold is used to make jewelry because of the attractiveness of its brilliance and because of its rarity. Nor does it tarnish and does not react with air like a metal such as iron does.
Gold is malleable, meaning that it can be beaten into very thin sheets. It's also ductile, meaning it can be stretched into the shape of a thin wire like on earrings. Gold is blue gold when alloyed with indium or iron, purple when alloyed with aluminum, black when alloyed with cobalt, and green when alloyed only with silver. For example, pure gold mixed with copper will tend to become rose gold (or red gold); gold mixed with platinum, palladium or silver will be paler and, if it is also rhodium-plated, will produce “white gold”.
The word “carat” (or carat, if written in the American style) originated in carob, which was used as a stable measure of weight to weigh gold and indicate its fineness. If gold were alloyed with other metals, such as copper, it would be less expensive than a piece of pure or almost pure gold. Yellow gold is a classic and modern gold alloy preferred by many jewelers and lovers of jewelry made by mixing gold with copper. It is created by mixing yellow gold with silver, copper and zinc and is commonly used with white and rose gold to create tasty color combinations in jewelry.
The different combinations and percentages of gold with other metals create products or types of gold pieces that are unique to the market. Gold sheets can be converted into a thin gold plate with which parts of entire buildings can be covered, and even cosmonauts' spacesuits have a very thin, transparent layer of gold over the visor to reflect the sun and protect their eyes. By the end of this reading, you'll also understand how the types of gold differ and discover the reasons why gold is the preferred metal used in most jewelry. Tutankhamun's death mask, a symbol of ancient Egypt, was made of pure gold, as were the gold treasures that surrounded his burial chamber.
But why is gold used in jewelry making? What makes this precious metal so special, compared to other materials or even to other metals. The association of pure gold with the gods and royalty meant that all aspiring men and women also coveted gold, so it was used to make jewelry. The gold standard is a monetary system in use today that sets the price of a unit of a currency against the price of gold.
