At this time, the tour guide Xiao Luo waved the pennant again and greeted the members of the Golden Autumn Troupe:

"Friends, assemble! Now, let's go to the diamond processing center for a tour. If any of you are planning to buy a real diamond, today is the best opportunity. ”

So, the members of the Golden Autumn Troupe followed behind Xiao Luo, discussing the delicate and delicate Dutch wooden shoes, praising the charming scenery of the suburbs of Amsterdam, and talking about the Dutch girl's stiff Chinese in the bungalow and her unique merchandising ability.

As the golden autumn group will go to visit the diamond processing factory, which is in the city of Amsterdam.

After leaving the parking lot of the Folk Village, the minibus returned to the city.

Fortunately, the folk village is less than 20 kilometers away from the city, and half an hour later, the minibus has stopped near a diamond processing factory called "Jiasheng Dima".

After the members of the Golden Autumn Group got off the bus, under the guidance of the tour guide Xiao Luo, they walked forward for two minutes and entered the gate of the "Jiasheng Dima" diamond processing factory.

Here, it is worth introducing the unique approach of the Amsterdam diamond processing plant to the outside world.

It turns out that all the diamond processing factories in Amsterdam are open to the public when they sell their products.

They allow visitors or customers to enter the factory directly, and can go directly to the factory's workshop to see the processing process of government and enterprise diamonds next to the machine tools.

In addition, the diamond factory not only allows outsiders to visit, but also arranges professional and technical personnel to introduce the processing methods and identification methods of diamonds to tourists or customers who enter the factory.

At the same time, each diamond processing factory will set up a special diamond sales shop on the street frontage, so that customers can buy the authentic diamond products produced by the factory immediately after the visit.

Under the leadership of the tour guide Xiao Luo, the members of the Golden Autumn Regiment entered the "Jiasheng Dima" diamond processing factory, and the factory specially invited the guests of the Golden Autumn Regiment to line up in order, first entering the door from the first floor of the factory's sales store, and then under the guidance of the store sales staff, they turned into a gate more than two meters wide from the left side of the first floor and directly entered the processing workshop.

After coming to the processing workshop, the members of the Golden Autumn Regiment saw that all the workers in the workshop were wearing blue overalls, and under the bright light, they were all concentrating on processing the diamonds in their hands.

After discovering that the group of tourists came, there was an engineer and technician in his forties in the workshop, who immediately greeted the Jinqiu group.

The technician came to the Jinqiu group and first enthusiastically said "Harrow" to everyone, and then he talked to the tour guide Xiao Luo in a foreign language.

After the tour guide Xiao Luo talked to him, the technician nodded and smiled.

Then, he gestured to the members of the Golden Autumn Troupe and invited them to follow him to a diamond processing machine.

The diamond processing machine here is actually only the size of an ordinary sewing machine.

At first glance, the machine is small and delicate, housed entirely in a glass case the size of a desk.

In the glass case, several high-intensity spotlights are installed from different angles to illuminate the machine tools in the cabinet, as well as the hands of the operators, as well as the diamonds they are working on in their hands.

The main task of the workers who operate the machine tool is to process the diamond raw materials into products according to the technical parameters finalized by the engineering and technical personnel in advance, and then hand them over to the warehouse keeper for storage according to the prescribed processes and procedures.

The technician who was in charge of introducing the diamond processing process led the group to a processing machine, then said something to the guide, and then explained it to the guests in Dutch.

With the explanation of the technical commissioner, the tour guide Xiao Luo also translated to everyone one after another.

The main content of the technical specialist's explanation was that the most basic and crucial thing in diamond processing is to choose good diamond raw materials.

After selecting the raw materials, they are cut into medium-sized particles according to the size and shape of the raw materials.

After the raw material is cut into pellets, the granules are processed by skilled workers into gemstones that shine on all sides.

After visiting the processing workshop, the technical commissioner who was responsible for explaining the diamond processing process led the golden autumn group back to the diamond sales store and invited everyone to the diamond appraisal counter.

At this time, there is a professional appraiser at the diamond grading counter, who is appraising a diamond for a client.

After a few words of conversation with the appraiser at the counter in Dutch, the appraiser immediately got up and nodded to the guests of the Golden Autumn Troupe.

Then, the appraiser holds the diamond being identified in one hand and a magnifying glass in the other, and constantly changes the magnifying glass in his hand, looking at the diamond in his hand from all angles, while giving fluent explanations to the guests in Dutch.

At this time, Xiao Luo, the tour guide standing next to the appraiser, began to translate the appraiser's explanation again.

Xiao Luo said in the translation:

"In order to determine the authenticity and quality of a diamond, it is necessary to grasp the following points:

The first is to identify the hardness.

The hardness of diamond is currently the strongest natural substance on earth.

It can be said that there is no other quality that can mark a diamond, and if it can be traced with other characteristics, it is definitely not a diamond!

The second is the thermal conductivity test.

When identifying a diamond, you can take a breath on the diamond and other similar objects at the same time, if it is a real diamond, the water mist on its surface will evaporate faster than the water mist on other items - because diamonds have extremely high thermal conductivity!

The third is to observe the reflected light.

Under the magnifying glass, you can see that the diamond's girdle is a shiny, very fine, frosted reflected beam. This reflected beam of diamond is unique among all the natural substances at present!

The fourth is to look at the growth point.

Under a magnifying glass, there are often grooved and triangular growth points on the crystal surface of genuine diamonds; Fakes are not likely to have these characteristics. ”

The appraiser at the counter used a magnifying glass to explain the diamond in his hand, and then said a few words to the tour guide Xiao Luo alone.

After listening to this, the tour guide Xiao Luo smiled and said to the members of the Golden Autumn Troupe:

"Just now, this appraiser asked me to tell you that it is not difficult to identify a diamond fake. Nowadays, there are three types of fakes that are commonly found in the market:

One is ordinary glass with alumina added.

Its refractive index and dispersion will be significantly improved, and it is easy to mislead people for the truth. But the hardness of this glass is far from the strength of diamonds.

The second is imitation of artificial zirconia. It is very hard and refracts the beam well. But when it rotates, it reflects more colored light; There is a significant difference between the real product and the real product, which only reflects faint yellow and blue light when it rotates.

The third is a fake imitation of a chemically synthesized sapphire or colorless pinnacle. This fake is close to the hardness of a real diamond, but it has a low refractive index and is birefringent. As long as you put it under a magnifying glass, you can see the ghosting. ”

After the translation, the tour guide Xiao Luo also asked everyone according to the meaning of the appraiser:

"The appraiser wants me to ask everyone, do you still have any questions? If anyone has any doubts, just say it, and he will explain it to everyone. ”

"Oh, no! This appraiser's explanation is already very concise! Xiao Luo, now ask the technical specialist to take us to buy diamonds, right? ”

It was Mr. Liu, a big man from Shandong, who didn't wait for others to speak, and took the lead in making a request to the tour guide Xiao Luo.

The tour guide Xiao Luo nodded in understanding, and then translated Mr. Liu's request to the technical commissioner and appraiser.

"Gude ——!"

The technical commissioner in charge of the reception immediately enthusiastically led the way in front and brought the golden autumn group to the commodity counter next to the appraisal counter.

After the members of the Golden Autumn Group came to the product counter, they took a closer look and saw that the counter was full of all kinds of jewelry, including platinum necklaces, gold necklaces, platinum rings, gold rings, platinum earrings, gold earrings, platinum nose ornaments, gold nose ornaments, as well as various men's and women's watches, bracelets, headwear, etc.

On the various pieces of jewelry mentioned above, there is one common feature:

It's that every piece of jewelry is inlaid with exquisite diamonds!

The number of diamonds set with diamonds varies according to the number and weight of the jewelry, which is really dazzling and I don't know which jewelry to choose.

Even so, the members of the Golden Autumn Troupe began to appreciate and carefully choose their favorite diamond jewelry according to their own preferences!
