Chapter 198：

Under other similar conditions, as the weight of a diamond increases, its value increases geometrically; diamonds of the same weight will have very different values ​​due to differences in color, clarity and cut.

The clarity of diamonds is usually graded by using a 10x magnifying glass to grade the internal and surface flaws of the diamond and their influence on the brilliance. , SI1, SI2, P1, P2, P3 a total of 10 levels.

Set diamonds are divided into excellent, very good, good, good, generally 5 grades.

IF, VVS, VS, SI, P are commonly used in the world to be interpreted as:

IF is perfect and flawless, and domestic is LC, that is, no flaws can be seen under a tenfold magnifying glass. Regarding this point, it is impossible for domestic diamond grading to give this level.

……

The clerk at the counter is not bad.

It was very clear to Zhou Ye.

Even some common sense has been said.

In addition to the convenient identification of diamonds, the identification of diamond ring settings is also mentioned.

There are many ways to identify the material of a diamond ring, but they are roughly divided into four types.

The first: sensory test the quality of the wedding ring.

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

The second method of identifying the material of the ring setting of the diamond ring: check the imprint.

National standards stipulate that precious metal jewelry should be marked with origin, manufacturer, material and content, and products without imprints are unqualified products. If there is a quality problem, the quality inspection agency can give inspection and judgment based on the imprint.

Consumers need to buy the brand and gold jewelry with different gold content they need according to the imprint.

The third method of identification of the material of the diamond ring setting: professional agency identification.

If you need to accurately know the content of precious metal jewelry 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 inlays and welding are firm or not, whether there are breaks, burrs, trachoma, etc.

The fourth method of identifying the material of the diamond ring setting: the difference between platinum 950 and platinum 900.

Platinum is referred to as PT, and everyone basically knows PT950. The general platinum ring is made of this kind of material, which refers to jewelry containing 95% platinum, and the remaining 5% is other precious metals, and the imprint is Pt950.

In contrast, T900 is a jewelry containing 90% platinum, and the remaining 10% is other precious metals, which are marked as Pt900. PT900 is harder and suitable for setting diamonds, while PT950 is purer and softer, with higher purity and better value preservation.

Most platinum ring settings are Pt900, but there are also a few manufacturers who use Pt950 to make settings.

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

In addition, there are some small gifts.

It's all worthless things.

For example, water cups and tea sets.

Although it is not worth the money, it can be used.

……

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

"Okay." Zhou Ye readily settled the bill and paid.

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

chapter 279

PS: Explosive update, please subscribe, please support!

Zhou Ye settled the bill very readily, and then took the receipt.

One of them is worth more than 360,000 yuan, and the other is worth more than 380,000 yuan.

about the same price.

Soon, the little beauty took the order and handed the packaged diamond ring gift box to Zhou Ye.

"Boss, see if you need anything else, we also have diamond necklaces and earrings."

Of course, the little beauty hopes to get more commissions.

I believe that every sale will be like this.

Who doesn't want to make money?

At this moment, a van suddenly stopped in front of the jewelry store.

Then, a few people rushed down.

Holding a weapon in his hand.

"Get down for me, get down." These people covered their faces and rushed out with guns in their hands.

Aggressive.

For a moment, everyone around was stunned.

what's the situation.

"Bang", with the sound of a gunshot, everyone realized that they had encountered a robbery.

"Wocao", everyone squatted down and shot their heads.

Some of the women were so frightened that they panicked, screaming and running out.

But before he ran out, he was shot to death.

This time, no one dared to act rashly.

She shrank in a corner, shivering.

Everyone's faces were full of fear, some were timid, and even scared to pee.

"We're only asking for money, not life, let me go, hurry up, move quickly, we only have one minute," the leader shouted to his subordinates.

"Yes", then a few big men came up quickly, smashed the glass with special tools, and put all the jewelry in it.

Plunder, naked plunder.

One minute, it is not long, and it is short.

At this time, the alarm device is automatically activated, but these people are not afraid at all.

"Wocao, he is so awesome. In broad daylight, the bright world dares to rob, it's really dick." Zhou Ye was also a little confused.

These people are too bold.

He even came out to commit crimes in broad daylight.

Isn't this really courting death?

In fact, these people are indeed courting death.

No, it should be said to be asking for death.

Because someone bought their lives.

They are all a group of desperadoes.

……

These people came quickly and walked even faster.

How much can you take in one minute.

Then, quickly evacuate.

Zhou Ye had a gun on his body, but with so many people, he didn't bring a bodyguard.

Isn't that courting death?

He took his life very seriously.

Seeing that the other party was leaving, how could Zhou Ye let them go.

You know, they are criminals.

Zhou Ye stretched out his hand, and a white, patterned poisonous bee flew out of his hand.

It is the White Jade Venomous Bee.

Because there is only one poisonous bee, and everyone is panicking.

How can I have the mood and time to observe these.

Seeing these criminals leave, they all fled.

Some things are gone.

No matter how valuable it is, can you have your own life worthwhile?

What a joke.

……

Zhou Ye also ran out, then found an unoccupied corner, released the poisonous bees again, and let the poisonous bees track them, and he quickly came to the place where he parked and chased after him.

The police are also coming quickly, but it will definitely take a certain amount of time.

On the way, Zhou Ye thought something was wrong.

Is the other party really robbery?

It's too courageous.

Because these poisonous bees have enslavement marks on their bodies, Zhou Ye can clearly know their location and what they are doing.

Zhou Ye didn't dare to chase too closely, for fear of revealing his whereabouts.

……

The public security department attaches great importance to this robbery.

A task force was immediately set up.

Strict investigation.

These people not only killed people, but also had firearms, a very lethal weapon, in their hands.

The police attach great importance to it.

Immediately organize troops, set up roadblocks, and scrutinize passing vehicles.

The police even mobilized the Skynet system and began to mobilize surveillance video along the road to monitor criminal vehicles.

Soon, the criminal vehicle was found through the monitoring system.

A group of them got on the highway.

Then, the major highway intersections were immediately armed.

But unfortunately, it's too late.

The police got caught.

These people have a plan and a purpose.

. . . .

According to the information transmitted by the poisonous bee.

Before these people hit the highway.

There was a division.

There were a total of eight people who robbed this time.

One is a guessing driver, and seven are robbers.

But there were only six who got off.

One of them was the custodian of the driver.

Because this driver is not a robber.

They stole this car.

At the same time, the driver was also kidnapped.
