    gold
    The history of gold is the history of human civilization. Thousands of years ago, when people discovered the first batch of natural gold grains, gold was considered valuable materials.

Now, the biggest consumption project of gold is jewelry production. In 1970, the world used for jewelry to produce 1062 tons, accounting for about 77%of the world's total gold consumption.

Because rare gold has some characteristics that can be comparable to gold, like gold, chemical stability and similar mechanical properties like gold. The jewelry made of rare gold system can almost reach the degree of chaos with the golden jewelry.
