What are the problems needed to pay attention to when buying a diamond ring in Beijing? How do you believe in so many jewelry stores in Beijing? Ask the experienced tube!

1. An precious metal that is more popular on the market: platinum

is generally divided into PT900, PT950, and some areas have PT850.

PT950 is alloy containing 95%platinum and precious metals containing 5%铑, 钯;

PT900 is 90%platinum and 10%铑, 钯 钯 钯Alloy,

PT850 and so on. The price of platinum is also the most expensive among all inlaid metals. Some people are habitually called platinum as non -standard.

2.k gold series:

in recent years, the limelight is flourishing, with its hardness and easy to match diamonds, jewelry, and gems, which are welcomed by young people. Essence

The writing G750 of 18K gold has the same meaning, all of which refer to gold with a gold content of 75%, adding 25%of other metals.

In the case of fixed golden ratio, add other metals, such as 钯, etc., while maintaining the golden ductility, it can increase the hardness of the gold and be more suitable for inlaid.

The original color of 18K gold is a bit brown metal. After the model is made, it must be plated on the surface before inlaid. For example, the white is called 18K platinum (the specification is called white 18K gold), the yellow is called 18K gold, and the powder is called 18K rose gold.

The color of the plating layer is achieved by adding other non -ferrous metals, such as rose gold adding copper. In particular, we must remind everyone that 18K platinum is not 75%platinum, but gold. After wearing 18K gold for a period of time, the color may be changed after the coating is worn, but the change will not be too large, just a bit brown and bright.

3. Other common inlaid metals include:

钯 钯: Most of them are PD950, the materials are relatively light, the price is relatively cheap, but it is easy to get dark after a long time.

In silver: S925 means that the pure silver content is 92.5%, commonly known as silver. Silver is easy to be oxidized and black, so silver used in jewelry is often plated with a layer of platinum outside. It is often used to inlay some lower valuable gems.

18GP is a cheap metal plating 18K gold such as copper, generally inlaid with some fake gems or other cheap gems.

The identification diamond
The diamond is the hardest substance in natural substances. Diamonds can be carved with any other gems, but any other gemstone is engraved with diamonds. It can also be carved with "standard hardness meter". The hardness is less than 9 degrees, and it is a fake diamond. Diamonds are also intimate. If a pen is drawn on the surface of the diamond, it becomes a continuous straight line, while other gems are intermittently intermittent. The above methods have a certain reference value in identifying diamonds. You can also observe through 10 times large mirror. Under 10 times the large mirror, most diamonds can see the flaws. There are triangular growth patterns. The surface of the diamond has "fire" light such as "red, orange, and blue". shining. The most accurate and reliable method is to use the "heat -guided meter" to measure heat -conducting data to distinguish between true and false diamonds, but the price of "thermal guide" is more expensive.

Since the diamond is a noble and luxurious jewelry, the market is currently instead of or claiming to be used in the market with cheap gems, artificial gems and even glass. n
① vermiculite: It is very similar to diamonds and is the best substitute for diamonds. The appraisal method is that because the vermiculite has polarization and a large double refractive index, when the vermiculite edge after 10 times the large mirror is used to observe the processing of the processing, it can be seen from its top surface. Shadow, and diamonds have no phenomenon.

② Glass: The folding index of the glass is very low, and there is no flashing color of the diamond; especially sinking into the water, the glass products are glory at all, and immediately expose the horse's feet.

③ Soviet diamond: That is, cubic oxidation, the earliest was successfully developed by the Soviets, hence the name. Soviet diamonds are artificial compounds, but they are very close to natural diamonds in terms of scattered and folding. They also have the seductive appearance of "fire". But its hardness (8.5) can be distinguished from each other. And thermal conductivity is much lower than that of diamonds, which can be identified by the "hot guide" and accurately distinguish it.

④ Crystal: Although the crystal is a transparent crystal of natural minerals, it is like diamonds after processing, but it lacks the colorful light of diamonds.

The appraisal of ruby ​​

The natural gemstone "ten red nine cracks". Natural ruby ​​without any flaws and cracks is extremely rare. The color of artificial ruby ​​is consistent, with less internal defects or crystalline wraps, clean, and large blocks. As a precious gem, natural rubies with more than 3 carats on the market are very rare. If you encounter a larger ruby, you must attract attention, because natural ruby ​​is thousands of times higher than artificial ruby. "Take medicine".

The natural ruby ​​has a strong "two -color". Crystal, garnet, red glass, etc.

The red spinel is very similar to natural ruby. The two are the most confused, so they must be particularly careful.

The mall will not introduce
The price at the same level of Cartier's stones is too high. A scared people

The weekly Dafu Xie Ruilin Hengxin I do can be relatively high enough

The price per cara American in the blue harbor claims that the same drill price is saved by half compared to the mall. Compared with the mall, it is still very advantageous

diamond bird environment decoration The China Trade Center is also very high -end and the price and per caramebi should also be between Bo Zhong

Iondi is also very good, but it seems that it is difficult to find a place. N Da Cheng Diamond Route is relatively low -priced on the network reputation. You can also

The reference can be made ~

It mainly depends on what type of choice. The luxury of the economy is still fashionable to go to blue harbor or diamond birds.
