The most powerful god in the city

"What?" the little beauty couldn't help but be stunned.

I thought Zhou Ye was joking.

"I said, I want the two rings just now, you wrap them for me", the rings are not very expensive, but the production is very beautiful and exquisite.

Of course, if you want a bigger diamond ring, Zhou Ye can also buy it.

But there is no need.

"Really", the little beauty is still unbelievable.

At this time, another salesman on the side also heard it, looked Zhou Ye up and down, and couldn't help sneering.

I thought it was a rich second generation.

But look at this dress, it doesn't look like ah.

Not a single brand.

"If you ink again, I'll regret it"

"Ah", the little beauty woke up instantly, "Boss, you wait, I'll go get you a bag"

"You······ You really want to buy it", the other beautiful woman in front of the counter widened her eyes.

Look at Zhou Ye's calm appearance.

It looks like it's affordable.

"Nonsense, I was originally here to buy something", Zhou Ye couldn't help but roll his eyes.

"Hey, tell me about these two diamond rings, is this diamond ring worth so much?" Zhou Ye was actually idle and chatting without 027.

Just learn more.

He really didn't know anything about diamonds.

I just know that this thing is expensive.

"Okay sir, then I'll explain diamonds to you first", it just so happened that he was also idle.

"The value of a diamond can be determined by the 4Cs in a normal case, with the exception of fancy coloured diamonds.

We are not colored diamonds, so we can also use the 4C parameters to identify", and then, the other party gave Zhou Ye a booklet.

There's a lot written on it.

It's dense, and there's a lot of information in it.

However, Zhou Ye couldn't understand it at all.

The so-called "4C" is the abbreviation of 4 words that start with C, which refers to the carat weight, clarity, color and CUT of diamonds.

By combining the four points of the "4Cs", you can easily determine the value and quality of a diamond (aebh). Diamond price = weight + luster + degree +.

All other things being equal, the value of a diamond increases exponentially as its weight increases, and diamonds of the same weight will vary greatly depending on the value of color, clarity and cut.

The clarity of the diamond is usually graded by using a 10x magnifying glass to grade the clarity grade of the loose diamond by the inside, imperfections and their impact on the brilliance, which is subdivided into LC, VVS1, VVS2, VS1, VS2, SI1, SI2, P1, P2 and P3 according to the standards of Huaxia National Inspection.

Mounted diamonds are classified into 5 grades: Excellent, Very Good, Good, Excellent, and Generally.

Internationally, IF, VVS, VS, SI, and P are commonly interpreted as:

IF is flawless, and the domestic LC is LC, that is, no flaws can be seen under ten times magnification, and it is impossible to give this level of domestic diamond grading in China.

······

The waiter at this counter is not bad.

explained it very clearly to Zhou Ye.

Even a little common sense was spoken.

In addition to the convenience of diamond identification, it also talks about the identification of diamond ring settings.

There are many ways to identify the setting material of a diamond ring, but there are four main types.

The first is to test the quality of the wedding ring through the senses.

Look at the color: pure gold is dark yellow, K gold has yellow, red, white and other colors, and imitation gold products are mostly copper alloys, the color is lighter. Weight: The specific gravity of gold is much higher than that of imitation gold products, such as a pure gold ring is about 5 grams, and imitation gold products of the same size are generally less than 3 grams.

Method 2 for identifying the setting material of a diamond ring: check the imprint.

The national standard stipulates that precious metal jewelry should be marked with origin, manufacturer, material and content, and unmarked products are unqualified products. If there is a quality problem, the quality inspection agency can give a test judgment according to the imprint.

Consumers should buy their own brands and gold jewelry with different gold content according to the imprint.

Diamond ring setting material identification method 3: professional organization identification.

If you need to know the content of precious metal jewelry accurately or there is a quality dispute, you should go to the jewelry quality inspection agency and use physical or chemical analysis methods for identification. When buying jewelry, it is also necessary to carefully check whether the stone setting and welding are firm, whether there are breaks, burrs, trachoma, etc.

Method 4 for identifying the setting material of the diamond ring: the difference between platinum 950 and platinum 900.

Platinum is referred to as PT, everyone basically knows PT950, the general platinum pair of rings are used this kind of material, refers to jewelry containing 95% platinum components, the remaining 5% for other precious metals, the mark is Pt950.

On the other hand, T900 is an ornament containing 90% platinum, and the remaining 10% is other precious metals, which is imprinted as Pt900. PT900 is harder and more suitable for setting diamonds, while PT950 is purer and softer, with higher purity and more value retention.

Most platinum settings are Pt900, but there are a few manufacturers who use Pt950 for their settings.

At this time, the little beauty walked up with the package.

In addition to this, there are some small gifts.

It's all worthless stuff.

For example, there is a water cup, a tea set.

It's not valuable, but it's usable.

······

"Sir, please pay here, I'll wrap it up for you", the little beauty was very excited.

"Okay", Zhou Ye checked out and paid very quickly.

Zhou Ye didn't know that a storm was coming!_
