full gold and thousand gold are pure gold! Symbol: the Au country has very clear regulations on every gold ornament sold by merchants. Gold ornaments must be listed to indicate their gold content and weight. Gold with a gold content of not less than 99% is called full gold. The gold with a gold content of not less than 99.9% is dark yellow, commonly known as two nines. The gold with a gold content of not less than 99% is called three nines. However, pure gold is generally not inlaid with gemstones because of its low hardness
2, [platinum]
strictly speaking, platinum has nothing to do with gold. Platinum is an extremely rare metal. It is white, hard and never fades. It has permanent value preservation and is generally matched with diamonds. Also known as platinum symbol: according to PT national regulations, only jewelry with a platinum content of 85% or more can be called platinum jewelry and must bear the PT mark
3, [3D hard gold]
3D hard gold or hard gold refers to the improvement of pure gold in the processing process through process improvement (the hardness and wear resistance of gold are greatly improved by improving the gold content, pH value, working temperature, organic gloss content and stirring speed in the electroforming solution), so that it has high hardness, good color and luster of the finished product, and is easy to be polished into various shapes, It overcomes the disadvantage of insufficient hardness of pure gold. Because of the complex processing technology, it will be a little expensive
4, [K gold], [white K gold]
[K gold] is a kind of identification for gold ornaments with different gold content. The gold content of 1K is about 4.166%, so the gold content of 24K, 22K, 20K and 18K is 99.99% (pure gold), 91.65%, 83.32% and 74.98% respectively. The rest can be multiplied by 4.166% by K number to get the gold content. [white gold] white gold is not gold but platinum
5, [gold plating]
gold plating is spraying a layer of gold on other metal surfaces
6. [color gold]
color gold is also called color gold. It is melted by adding a variety of color metals to gold. The price will become more expensive with the rarity and novelty of the color. It is different from hard gold and can be recycled
extended data:
identification of adulteration of gold:
1. Whether gold has white bright spots
cut gold bars or gold jewelry with material scissors, and observe its section with a magnifying glass. If you see white bright spots, because gold and iridium cannot be fused together, it indicates that iridium is mixed in the gold
2. Measure 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 tested gold bar into the measuring cup and observe whether the scale of water rises or falls. If there is any change, it means that the gold bar is not pure gold. But if it is gold jewelry, this method is not applicable, because there is air in the gold jewelry
3. Real gold is not afraid of fire
burn gold bars or gold jewelry on the fire for a while to observe their changes. Because iridium will combine with oxygen in the air to produce oxidation reaction, gold bars with insufficient purity will turn grey; And pure gold will glow red after being roasted. However, this method may damage jewelry to some extent
Take a look at the types of gold introduced to you: 1. Pure gold jewelry pure gold jewelry has a gold content of more than 99%, up to 99.99%. Pure gold jewelry has a soft texture, teeth bite marks, and is easy to bend. The color is golden, pure, and soft. It feels heavy and heavy 2. Gold plated jewelry is a layer of gold plated on the surface of other metal jewelry by electroplating. The color is similar to that of real gold jewelry. It is bright and difficult to identify in new times. However, gold-plated jewelry has a lighter feel, a harder texture, and no marks on teeth, which is easy to fade after a long time 3. Colored gold jewelry refers to wrapping 24K or 22K gold foil on other metal surfaces. If the K number of gold foil is too low, its softness is poor. The appearance of gold covered jewelry is similar to that of real gold jewelry. It is glittering and hard to fade, making it difficult to distinguish between real and fake 4. 3D hard gold jewelry 3D hard gold uses different processes at different positions, some polished, some frosted, resulting in light and dark contrast. The layering of colors is clearer, the sense of three-dimensional is stronger, and the texture is also differentiated. When it is touched, some places are smooth and delicate, and some places have a slight frosting feeling, which makes it feel rich. The biggest difference between 3D hard gold and traditional gold lies in hardness and wear resistance 5. Imitation gold jewelry imitation gold jewelry is a kind of jewelry similar to K-gold made by special plating process. Imitation gold jewelry is also known as sub gold jewelry. Its appearance is golden yellow, but the jewelry actually does not contain gold. Instead, it is made of copper, nickel, zinc and other metal elements as raw materials into semi-finished products. Then it is put into a special plating solution and plated with a layer of red yellow bright plating like gold on the surface. The appearance of imitation gold jewelry is very similar to pure gold, but the jewelry does not contain gold 6. Copper jewelry the color of copper jewelry is yellow with red, false hair, dark luster, soft texture and light weight. Whether it is gold-plated jewelry, gold-clad jewelry, copper jewelry or sub gold jewelry, it generally does not carry a seal similar to gold jewelry. Or the signet is different from gold jewelry. For example, some jewelry is engraved with the English letter "GK", which means "gold plating" 7. Copper alloy jewelry copper alloy jewelry (copper tin alloy) is white in color, hard and light in quality. If it is worn for a long time, it will make the skin black. The main types are pure copper, simple single copper, tin bronze, aluminum bronze, white copper and so on.
There are roughly six kinds of gold: 1, [Full gold], [thousand full gold] full gold and thousand full gold are pure gold. Symbol: the Au country has very clear regulations on every gold jewelry sold by merchants. Yellow gold jewelry must be listed to indicate its gold content and weight. If the gold content is not less than 99%, it is called full gold, and the gold content is not less than 99.9%. Full gold is dark yellow, commonly known as two nines, and full gold is three nines. However, pure gold is generally not inlaid with gemstones because its hardness is not
2. [platinum] strictly speaking, platinum has nothing to do with gold. Platinum is an extremely rare metal. It is white, hard and never fades. it has permanent value preservation and is generally matched with diamonds. Also known as platinum symbol: according to PT national regulations, only jewelry with platinum content of 8 5% or more can be called platinum jewelry and must bear the PT mark 3. [3D hard gold] 3D hard gold or hard gold refers to the improvement of pure gold in the processing process through process improvement (the hardness and wear resistance of gold are greatly improved by improving the Yellow gold content, pH value, working temperature, organic gloss content and stirring speed in the electroforming solution), so that it has high hardness, good color and luster of the finished product, and is easy to grind into various shapes, It overcomes the disadvantage of insufficient hardness of pure gold, which is a little expensive because of the complex processing technology 4.
