Hello! I would like to know which is better, gold or karat gold?

This depends on personal preference, but also depends on what products to buy, ** can not be matched with diamonds, if there is a thousand pure gold complex, there is no comparison, I personally still prefer K gold.

If you buy a necklace, it is good to have gold, and it is good to invest. K gold is containing 75% **, buy with the chain to K gold-based, K gold is rich in color, the hardness is relatively high. Therefore, it is suitable for pendants of various materials, and it is highly firm and not easy to break.

If it is a young girl to buy, it is recommended to choose a K gold necklace, especially the kind of letter clavicle chain is very delicate and particularly durable.

**It is relatively soft, if it is not with a chain, that is, a necklace worn alone, then you can buy**, if it is a necklace that needs to be matched, **can only be matched** pendant, with other pendants will have a lot of wear and tear. From the point of view, if you buy it in a jewelry store, K gold is more expensive than it. From the point of view of value preservation, it must be ** hedging.

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

Internationally, it is generally measured in ounces, and in ancient China, it was "two" 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.

Physical. Color:

When gold is melted, the steam emitted is yellow-green; During the smelting process, its gold dust is usually brown; If you cast it into a thin sheet, it can even transmit green light.

Malleability: Exceptionally strong. One ounce of gold can be drawn up to 50 miles long, and its malleability makes it easy to cast, making it an excellent choice for jewelry. Gold is the most tensile of all metals.

Malleability: Second to none. It can create extremely thin gold flakes that are easy to roll up.

One ounce of gold can be hammered as thin as 1 foot thick and 100 square meters large. In ancient times, it was hammered into thin sheets to decorate temples and palaces. These can illustrate the flexibility and malleability that ** has.

**The color is golden yellow, metallic luster, and difficult to decompose. density, melting point; It has good ductility, can be pressed into thin foils, has extremely high heat transfer and conductivity, and the resistance of pure gold is. Pure gold has good chemical resistance and is the best electroplating material.

**As a kind of ***, it has good physical properties, "real gold is not afraid of fire refining" is that gold has high chemical stability, and it is not easy to react with other substances, so there is no need to worry about oxidation and discoloration. Even in the molten state, it does not oxidize and change color, and it still shines golden after cooling.

High density and heavy feel. Good toughness and ductility, good conductivity. Pure gold has a brilliant yellow color, but the color changes greatly when mixed with other metals, such as dark red for gold-copper alloys and light yellow or off-white for silver-containing alloys.

Gold is easily ground into powder, which is why gold is dispersed in nature, and pure gold jewelry is also easy to be worn down to reduce the weight.

First, the gold content is different.

1. K gold: the gold content is divided into 22K gold (gold content, K gold, K gold (etc.)

2. **: The content reaches the above**.

Second, the English expression is different:

1. K gold: karat gold.

2. **:p ure gold or solid gold.

Third, the characteristics are different:

1. K gold: Because of its perfect proportion, it has the advantages of strong ductility, high hardness and changeable color, and can be used in jewelry design to give full play to complex and exquisite creative performance.

2. **: Thousand pure gold has its unique golden yellow luster, and pure gold will shine dazzling when placed in strong light.
