Is there gold in ordinary yellow sand? Is sand gold the same as gold?

Yes, but it is very rare, difficult to refine, and the cost is too high!

Sand gold is also a kind of **, produced at the bottom of the river or low-lying areas, mixed with stone sand, is washed out of the **, the gold content of the two is different:

1. The gold content is different: the gold content of sand gold is low, and the gold content is about 5%, while the ** seen in China is all pure gold, and the gold content is in.

2. Different degrees of softness and hardness: Shajin is hard, while China** is soft.

3. Different colors: The color of sand gold is golden yellow at first glance, and it is whitish when you look closely, and the color is real golden yellow.

1. Identify adulteration:

1. Whether there are white bright spots, cut the gold bars or gold jewelry with material scissors, observe its cut surface with a magnifying glass, if you see white bright spots, because the ** and iridium can not be fused together, it means that the ** is mixed with iridium.

2. To 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 submerge the gold bar. Then put the gold bar to be tested into the measuring cup, observe whether the scale of the water rises or falls, as long as it changes, it means that the gold bar is not pure gold. However, this method does not apply to gold jewelry, because there is air in it.

3. Real gold is not afraid of fire, put gold bars or gold jewelry on the fire for a while to observe its changes. Because iridium will oxidize with oxygen in the air, gold bars of insufficient purity will turn gray; Pure gold, on the other hand, will be red and shiny in color after being roasted by fire. However, this method may be destructive to jewelry.

If you travel to Southeast Asia, especially Vietnam, there is a local ** jewelry that must be cautious when buying. This kind of **jewelry looks very similar to China's**, but ** is much cheaper than the domestic one, many friends feel that they have picked up a big bargain, but if you really buy, to the same goods in China, you may feel how serious a mistake you have made.

And not only Vietnam, there are this kind of ** in many regions, his name is Sha Jin, simply put, it is a ** scooped out of the mud and sand. If you don't look carefully, you can't see the difference between this kind of sand gold and **, and only those who really know how much difference there are between the two. Next, I will tell you about the origin of this sand gold.

The word "sand" in Shajinsha Jinsha illustrates its production method. Sand gold is mined in the low-lying area at the bottom of the river, that is, the gold is first seen after the yellow sand is exhausted. However, although there is a gold character in the sand gold, in fact, the gold content of this gold is relatively low.

Shajin that has not been purified is actually very cheap, because it contains too many impurities. And unpurified sand gold is also called raw gold.

The main difference between Vietnam and China's ** is actually in the gold content. You should have heard of the saying that pure gold means 999 gold, and the content of sand gold in Vietnam can only reach 99 gold. The current ** in the Chinese market is pure gold, and this kind of scarf in Vietnam is also called 24k**.

There is still a certain difference between the two in appearance, for Vietnamese sand gold, if you look carefully, you can find that although Vietnamese sand gold is golden at first glance, but if you look closely, he is a little white.

At the same time, we all know that the texture of ** is relatively soft, that is to say, the higher the content of **, the softer the texture. However, Vietnamese sand gold is relatively hard, and this is because of its relatively low gold content.

Sand gold is also gold, on the surface, sand gold and ** in color is not much different, it and ** the biggest difference is in the content, with the method of identification ** can distinguish them.

Sediment gold deposits are formed in low-lying places, and are formed by weathering, denudation, transportation and sedimentation of upstream rocks containing gold mineralized zones or gold veins or gold deposits.

The most gold content is in the Quaternary strata near the Quaternary contact zone with the bedrock.

There is no difference between sand gold and primary gold, and it has to be purified.

Summary. Hello dear, Shajin is generally not **, beware of being deceived.

Hello dear, Shajin is generally not **, beware of being deceived.

That is to say, sand gold is also **, but it is the gold that falls off from the gold bench mine, and then after a long period of sedimentary nuclear collapse, it becomes what we often call sand gold now. Therefore, "sand gold usually has different sizes, the large ones resemble broad beans, the small ones resemble fine sand, and the shapes and clothes are different. The color also varies depending on the fineness, more than ninety percent of it is reddish yellow, and the so-called sand gold can be literally understood as Utano, which is gold mixed with sand.

The gold content of one gram of sand gold is about 5% of the gold content of one gram, so according to the gold price on the market, the gold content of sand gold is maintained at dozens of yuan per gram.

Shajin is screened and refined from sand, so it contains a lot of magazines, and ** is the product after a special purification process, so the quality of jewelry made of sand gold can not be compared with ** jewelry. The ancients said that real gold is not afraid of fire, and the jewelry made of sand gold and the jewelry made of ** will be found to be different after wearing it for a long time. The jewelry made by Shajin will lose its initial luster after wearing it for a long time, and even fade, while the jewelry made by ** as long as it is cleaned and tried, the luster is as good as ever.

In addition, if you lose quickly, you can find that the details of the jewelry made by Shajin are not as good as the details of the jewelry.

The difference between Shajin and ** is as follows:

1. Shajin is a kind of **, which belongs to raw gold. The difference between sand gold and ** is mainly in the purity, the purity of the sand gold extracted by washing is equivalent to the ** of 95 and 96, so it is also much cheaper. If it is melted and refined, it becomes cooked gold, and thus the purity will be higher.

2. Sand gold is produced at the bottom of the river or in low-lying areas, mixed with stone sand, and washed out. The size of the sand gold grains varies, from the large ones like broad beans to the small ones like fine sand, with different shapes. The color varies according to the level of color, more than ninety percent is reddish yellow, eight becomes pale yellow, and seven becomes blue-yellow.

The color varies according to the level of color, more than ninety percent is reddish yellow, eight becomes pale yellow, and seven becomes blue-yellow.

4. Generally, if it is jewelry made of sand gold, the merchant will indicate it, because it is cheaper than ten or twenty-one grams of sand gold on the **.

5. Gold is a simple form of the chemical element gold (chemical element symbol AU), which is a soft, golden-yellow, corrosion-resistant element. Gold is one of the rarest, more precious and most highly valued metals.

6. In the world, the first is generally measured in ounces, and in ancient China, "two" was used as the unit, which is a very important metal. It is not only a special currency for reserves and investment, but also an important material for the jewelry industry, electronics industry, modern communications, aerospace industry and other sectors.

In fact, Shajin itself is also a kind of **. The exposed gold ore on the ground is weathered and cracked after a long period of wind and rain, and the gold is separated from the veins and deposited in the sediment, mixed with the stone and sand at the bottom of the river or in the low-lying area, and the sand is obtained by washing. However, the gold content of sand gold is very low, and it can only be said to be a "distant relative" of **.

Now the sand gold jewelry on the market, most of them are domestic alloy gold-plated jewelry, or alloy Qingpei jewelry that does not contain gold at all, it is just a variety of metal materials, made of the best color and texture, they are usually called Vietnamese sand gold. ** Jewelry ** Jewelry Sa Gold Vietnam Sa Gold 2022-11-19 It's a wasteland, click.
