Amazing Gold

Gold is one of the most extraordinary elements known to man. Admired for thousands of years and used extensively in jewellery, this metal has some amazing statistics. It is almost indestructible, requiring a special mixture of 2 acids (sulphuric and hydrochloric) to cause a reaction. No single acid will be able to elicit any damage by itself. Gold is non-toxic and does not rust.

All the gold every mined on earth would fit into a cube with sides around 19 metres in length. This amounts to less than 25 grams for each and every person living today, about the amount in a medium gold necklace.

It can be beaten so thinly that it is possible to see through it, no other metal can claim this ability, and it is used on astronaut's visors. Just 31 grams can be made into a sheet of 16 square metres in size.

Gold is the 3rd best conductor of electricity behind silver and copper and as it won't corrode it is widely used in electronic devices, especially on contacts in relays and the circuit boards in computers. It melts at 1064 degrees Celsius and a cube with 10cm sides (one litre) weighs 19.3 kilograms, consider that a litre of water weighs just 1 kilogram.

The largest single gold nugget ever found weighed in at around 70 kilograms and would be worth over 3 million dollars. To put that in perspective, it would fit inside a one gallon milk container. A cubic foot of gold, around about the size of a milk create, would weigh a massive 500kg.

It is no wonder with all these special properties that it has become the premium choice for quality jewellery in all its forms. Solid gold chains look great and will bring a lifetime of pleasure for the lucky owner.
