Most gold used in jewelry is alloyed with silver, copper, and a little zinc to produce various shades of yellow gold or with nickel, copper, and zinc to produce white gold.
Gold is a soft, dense, yellow metal. Its chemical symbol is Au. Its atomic number is 79. As a precious metal, it has been used for many thousands of years by people all over the world, for jewelry, and as money.
Scientists have long known that veins of gold are formed by mineral deposition from hot fluids flowing through cracks deep in Earth's crust. But a study published today in Nature Geoscience1 has found that the process can occur almost instantaneously — possibly within a few tenths of a second.
Gold is primarily found as
the pure, native metal. Sylvanite and calaverite are gold-bearing
minerals. Gold is usually found embedded in quartz veins, or placer
stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia and Canada
Gold is metallic, with a yellow colour when in a mass, but when finely divided it may be black, ruby, or purple. It is the most malleable and ductile metal; 1 ounce (28 g) of gold can be beaten out to 300 square feet. It is a soft metal and is usually alloyed to give it more strength.
Characteristics: Gold is an excellent conductor of heat and electricity. It is a soft, yellow metal with a beautiful lustrous sheen. It is the most malleable and ductile of all the elements and a single gram can be beaten into a one square meter sheet of gold leaf.
Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides
G old minerals form in hot rocks in and around volcanoes. Low sulfur, gold-bearing hydrothermal fluids form when hot rocks heat ground water. An example of these low-sulfur fluids are hot springs like those at Yellowstone National Park. The ores of Round Mountain, Nevada, are typical low-sulfur deposits.
Uses of Gold.
- Dentistry and Medicine: Gold is considered as the best filling for cavities and crowns, bridges and other orthodontic appliances because the metal is ductile and can easily take shapes.
- Electronics and Computers.
- Medals and Statues.
- Jewellery.
- Medicine use of gold
When is gold treatment used? Gold is used most often to treat rheumatoid arthritis. It is sometimes also used to treat juvenile rheumatoid arthritis and psoriatic arthritis. Gold appears to work best in the early stages of arthritis but it may be effective in anyone with active joint pain and swelling.
Things That Are Gold
- Jewelry.
- Ring.
- Bracelet.
- Bangle.
- Earring.
- Pendant.
- Necklace.
- Choker.
Throughout history, gold has been seen as a special and valuable commodity. Today, owning gold can act as a hedge against inflation and deflation alike, as well as a good portfolio diversifier. As a global store of value, gold can also provide financial cover during geopolitical and macroeconomic uncertainty.
