Uses of Gold:

  1. Jewellery - As stated above 49% of all gold mined is used for jewelry. 
  2. Gold is still used in dentistry though in a world today where everyone is too conscious about looks, the use is getting less and less. The first book published on dentistry, entitled Artzney Buchlein, appeared in 1530. The book suggests dentists fill cavities and rotten teeth with gold. Gold is a bio-compatible metal, meaning it can be placed in contact with a person's body and not cause harm to one's health.
  3. Gold is a highly efficient conductor of electricity and is used in most electronic devices, including cell phones. Gold contained in connectors, switches and relay contacts allows phones to remain free of corrosion.
  4. According to the World Gold Council, a single mobile device contains up to 50 milligrams of gold. That’s a tiny amount but nearly 1 billion cell phones are produced each year. With a gold value of about 50 cents in each phone, that adds up to $500 million dollars in gold each year!
  5. Gold can also be found in most standard desktop and laptop computers. The precious metal is used in a CPU’s memory chip and motherboard, allowing parts of your computer to receive power and communicate with each other.
  6. Gold acts as a reliable conductor, allowing for the rapid and accurate transmission of digital data from one device to another. In fact, only silver and copper are better conductors of electricity.
  7. The earliest medical use of gold can be traced back to China in 2500 BC. Chinese physicians used pure gold to treat furuncles, smallpox, skin ulcers and to remove mercury from skin and flesh, says GoldBulletin. In India Gold is even today used in various forms for ayurvedic treatments.
  8. Today the metal is primarily used to treat patients with arthritis. Gold salts are used to reduce swelling, bone damage and to relieve joint pain and stiffness. It’s a slow process; patients generally receive 22 weeks of gold injections before experiencing relief.
  9. Gold is highly malleable and flexible. Gold can be beaten into thin sheets, only a few millionths of an inch thick. These sheets, known as gold leaf, are displayed on buildings throughout the world, such as St. Michael’s Cathedral in Kiev, Ukraine.
  10. India’s Sripuram Golden Temple is the world’s largest golden structure. The spiritual park is made out of 1.5 tons of gold. The gold leafing provides a durable and corrosion-resistant covering, says GoldPrice.com.
  11. It’s truly a gold universe. Space vehicles are fitted with gold-coated polyester film to reflect infrared radiation and to help stabilize core temperatures, says Geology.com. Without gold, darker colored parts of spacecraft would absorb significant amounts of heat.
  12. NASA also protects its astronauts using gold. Astronauts’ helmets are covered by the extravehicular visor assembly. The visor is coated with a thin layer of gold to filter out the sun’s harmful rays, according to NASA.


Difference between Ounce and Troy Ounce

Most people don't realize that there is a difference between an ounce and a troy ounce. Ounce is used to measure commodities and when you go to a departmental store you could be weighed commodities in ounces, however gold is weighed in troy ounces.

One troy ounce weighs
31.1 grams
One avoirdupois ounce weighs
28.35 grams

Precious metals such as gold and silver are often sold by the troy ounce. Many people don’t realize that an ounce of gold is more than the typical ounce found at the grocery store.  In many English speaking countries there are two systems for measuring weight.One, for precious metals, called the troy ounce.The other is for Commodities such as sugar, grains, and other grocery items. It is called the avoirdupois ounce.  

It is thought that the troy ounce was named after a weight system used in Troyes France during the Middle Ages.

Tola or Tolah System for Gold used in India.
In India we typically used the tola system and gold and silver was sold in Tolas which is slighly more than 10 grams.  1 Tola [India] is equal to 11.6638125 grams. However now in the newspaper the quote for Gold price that you see is per 10 grams and increasingly the tola system is not used.
