alien jewelry wholesale Human understanding and utilization of platinum are far later than gold, which is only about 2,000 years of history. According to archeological data demonstrations, in more than 700 BC, the ancient Egyptians had been able to process platinum into a high level of platinum accessories. Indians in Central America, before Columbus discovered the New World, also prevailed in platinum accessories. However, people in other regions know nothing about platinum. Until the beginning of the 16th century, the Spanish colonial empire gradually formed, and a large number of Spanish adventurers swarmed to Africa and the Americas to explore golden treasures. At that time, when the river in Ecuador was rushed into gold, it was repeatedly found that a white metal was mixed in gold, which was actually precious platinum. However, due to the underdeveloped science and low recognition ability at that time, facing the silver -shaking platinum, the colonial ruler called it "bad silver" and abandoned it.
In 1748, the famous Spanish scientist Anthony Luoa found a silver -white natural platinum in Pingto River Gold Mine. He conducted a careful study and found that the chemical properties of natural platinum were very stable, excellent in ductility, high melting point, extremely density, and obviously different from metal silver. As a result, Anthony became the first scholar to study platinum.
In 1780, a clever craftsman in Paris created platinum rings, brooches and platinum necklaces for the King of Louis XVI in France. As a result, Louis XVI has become the first person in the world to have platinum jewelry. Since then, the reputation of platinum has been rejuvenated, and it has jumped on the gold jewelry and is spoiled by the relatives of the emperor, the noble official, and the wealthy Jia Shang.
In nature, platinum reserves are scarce than gold. The annual output of world platinum is far less than gold. The global jewelry industry is only 3%of gold consumed in the world. Coupled with the high platinum melting point, pure melting platinum is more difficult than gold, and energy consumption is higher. Moreover, processing platinum requires a higher level of technology than processing gold. Therefore, platinum is a kind of precious metal that is more rare and more precious than precious metals such as gold and silver. Platinum is more expensive than gold.
Because of this, platinum has not been used as a currency circulation market. The output is scarce and it is difficult to refine. There is no enough "quantity" as a currency. Tributes, instead of being stored in the state treasury and treasury like gold and silver.
