Gold is a simple form of chemical element gold (chemical element symbol Au), which is a soft, golden yellow and corrosion-resistant precious metal. Gold is a rarer, more precious and more valuable metal. Generally speaking, gold in the world is measured in ounces. In ancient China, gold was measured in ounces, which was a very important metal. It is not only a special currency for reserve and investment, but also an important material for jewelry industry, electronics industry, modern communication and aerospace industry.
The chemical symbol of gold is Au, and the financial English code is XAU or gold. The name Au comes from a story of Aurora, the goddess of dawn in Roman mythology, which means shining dawn. After the international gold price entered 20 15, it soared all the way. The gold price in new york market rose from $0/200 per ounce to $0/300 per ounce in less than a month. Statistics show that since 20 15, the price of gold futures in new york market has increased by 9.3%.
Distinguish adulteration 1. Does gold have white highlights? Cut out gold bars or jewelry with scissors, and observe its cross section with a magnifying glass. If you see white bright spots, because gold and iridium can't blend together, it means that gold is doped with iridium. 2. Measure the specific gravity. First, measure the weight of a pure gold bar with a balance, then put the gold bar into a measuring cup and pour water to drown it. Then put the detected gold bars into a measuring cup and observe whether the scale of water rises or falls. As long as there is a change, it means that gold bars are not pure gold. But if it is gold jewelry, this method is not applicable, because there is air in gold jewelry. Real gold is not afraid of fire. Put gold bars or gold jewelry on the fire for a period of time and observe its changes. Because iridium will combine with oxygen in the air to produce oxidation reaction, gold bars with insufficient purity will turn gray; And pure gold will appear bright red after being baked by fire. However, this method may have some damage to jewelry.

According to the analysis report of China Gold Industry Market Prospect and Investment Strategic Planning, from April 20 13 to the middle of 20 15, the international gold price has been in a downturn after a sharp drop. Judging from the global economic situation, the world economic growth rate may pick up slightly in 20 15, but the overall recovery is weak. The volatility of international financial markets and commodity markets has intensified, and non-economic factors such as geopolitics have a greater impact, and there are still many uncertain factors. With the strengthening of the US dollar, the prices of commodities such as gold, non-ferrous metals and oil are all running at a low level at 20 15, and the low price of gold may become the "new normal" in the next few years.
