Gold is precious because of the following :
- is a rare metal(throughout world history have been drawn about 88,000 tonnes of gold.Annual extraction ranges around 1,500 tonnes.).If all the gold in the world would be gathered together would form a cube with sides of less than 17 meters.
- is very resistant to the action of chemicals.
- gold retains its brilliance in time.
- difficult to extract
- can be processed easily
- is malleable and ductile
- from an ounce of gold (31.10 grams) could be processed a string of 80 km or a sheet of one square meter gold.
- in the last 38 years the gold price rose continuously from $ 65 an ounce to about $ 1,300 today.Next year is estimated to grow to $ 1,600 per ounce and in a short time (approx.5 years) $ 2,300 per ounce.
Gold rated as 24 carat is practically 100% gold (pure gold) but only pure gold alone can not be used for the manufacture of jewelry because it isn't resistant enough.The alliance with nickel and silver creates white gold , or with copper and nickel creates pink gold or red.
in Europe is most appreciated the 18 carats gold and 14 carats in the U.S..
