First, what are the golden classification. In order to better use gold, the current gold category gold spot, paper gold, physical gold, gold jewelry, gold futures, golden futures, platinum-silver-gold gold, gold and silver coins. 1. Gold spot is the market transaction of physical delivery, such as gold bars and gold coins. This is a virtual book transaction. There are related accounts in the form of digital symbols. Buying and selling earns the difference. Banks are financing. Market participants mainly include gold producers, refiners, central banks, investors and other needs. 2. Paper gold is to convert gold into paper transactions, which does not involve the extraction of related physical gold. Through the "golden passbook account", low -buy high sale to obtain the difference in profits. It's low and convenient. 3. The real gold sale includes transactions such as gold bars, gold coins and gold jewelry, and holds gold as investment. Because this kind of pure object exists, the number of holdings will generally be less, because the income profit generates less. 4. Gold jewelry is more people know. Some of us usually wear rings, necklaces and the like, and some are also used to inlay gems. 5. The purchase and sellers of gold futures are sold and purchased the same contract with the previous contract before the contract expires, that is, liquidation, no need to truly deliver solid gold. Each transaction profit or loss of contract trading difference. This way of buying and selling is what people usually call "frying gold." 6. Options are the price agreed by buyers and sellers in the future, and have the right to purchase a certain amount of target rather than obligations. If the price trend is beneficial to options traders, it will exercise its rights and profit. If the price trend is not good for it, give up the right to buy, and the loss is only the cost of buying options at that time. 7. Platinum is also one of our well -known jewelry. Because of the small output, it is also more precious. 8. There are 4 types of gold and silver coins, gold and silver circulation coins, gold and silver commemorative coins, gold and silver trading coins, pure gold and silver coins (or gold and silver ingots). Second, goldenness. The purity of gold is generally divided into 24K and 18K. Usually, the pure gold is represented by 24K, that is, the gold content reaches 99.96%. It is also called a thousand -foot gold. The higher the purity, the more pure and full the color of the gold. 18K is made of gold combined with other metals. 8K gold not only retains the color of the gold, but also changes the soft nature of the golden texture, but also expands the choice space of consumers. At present, 18K gold has three colors: yellow, red, and white, and consumers can choose freely.
1. Look at the color. The pure gold is moist and glittering, including gold 70 % of its jewelry is yellow, and 80 % of gold is yellow. 2. The proportion of gold is 19.3g/cm3, and when the proportion is close to 19.3, the higher the pure gold. With the weight of the hand, the size is consistent with whether the volume is large and the shape is lighter. 3. Try soft and hard. The higher the gold ornament of the gold ornament, the softer, and the more elasticity. The real gold will have light marks with teeth or needles. The low -colored gold decorative steel is hard, and the heavy mixes are elastic, crispy and easy to break. 4. Listening sound. Two of the same gold jewelry collided, those with high colors, their voices, low -incorporated people's voice, mixed gold, their voices.
The easiest way to distinguish the purity of gold is actually the steel print of gold. Generally speaking, gold products need to be put on the corresponding steel print. Generally, the steel print contains the material and purity information of gold. Generally writing is AU999 or G999, etc. The following numbers generally correspond to purity. 999 generally refers to about 99.9%. AU750 refers to 18K gold, with a purity of about 75%.
It can also be identified by observing the color method. Gold generally has the saying of seven greens, eight, yellow, nine purple and red. It means that if the purity of gold is around 70 %, it is yellow in the yellow, and 90 % will present a certain purple, and the gold is red yellow.
The most accurate way is to detect professional tools, such as spectrometers. However, these machines are generally more expensive and need to go to specialized institutions to operate.
