If you learn from Ann, you can learn this ancient chiseling technique, right? Especially for irregular rough diamonds, this technique is the most time-saving and material-saving treatment.

Yan Wan's heart was pounding, and she naturally thought of Yan Yixin, who accompanied her to observe this almost lost technique. He said he would be back in three days, and he ...... today It's the third day!

Suddenly felt a little hot in her heart, just a few days of warmth, it made her feel that she hadn't seen her for a day, like every other autumn. The ancients were honest and deceived me, and separating lovers in love is probably one of the cruelest things in the world, right?

"What's wrong?" Lu Wenjun's voice brought her back to reality.

The sawing machine has already begun to work, and the engineers and workers are solemn, holding a book in their hands, probably recording relevant data.

"It's nothing, the first time I saw the diamond being opened, I was a little nervous." Yan Juan hid his emotions, only to find that his palms were already slightly wet.

The engineer relaxed and said to the worker, "There shouldn't be any problems." You just have to take care of this one today, and I'll keep an eye on it. ”

"Is this also a sawing machine?" Yan Juan felt that her face was a little hot, and turned her gaze to the other side in embarrassment.

"Yes, this is a laser saw." Lu Wenjun immediately interfaced, and finally found a place that could be expressed, "Laser cutting is a commonly used sawing method now, fully computerized, with good stability and time-saving." It only takes twenty seconds to sawn a carat. ”

"Then why not use this saw?" Yan Wan looked at the sawing machine that had just been started in confusion, according to the engineer, it might take less than twenty hours for this blue diamond to complete all the sawing. In other words, it will not be until tomorrow morning that the sawing is complete.

"Although this sawing method saves time and effort, and allows for continuous cutting, it is more costly for the diamond. Therefore, for good quality diamonds, we generally use the traditional cutting method. Lu Wenjun explained.

The laser sawing machine is working, the diamond moves back and forth, is "vaporized" by the strong laser beam, and the cutting speed is really fast. A two-carat white diamond is broken, and in a matter of minutes, the entire process of cutting is completed.

"Aren't these diamonds of very good quality?" Yan Wan asked.

"Yes. So like this blue diamond, we still use this traditional cutting method to preserve its original weight as much as possible. Lu Wenjun explained.

Workers are coating the saw blade with diamond powder, a job that needs to be repeated many times throughout the sawing process.

The engineer and the worker talked a few words, then turned and left.

"He'll put this diamond here?" Yan Juan asked in surprise, "This is the best blue diamond!" ”

"There's a video TV over there, so you can see it better than here. If something was wrong, he would have rushed over immediately. If it weren't for the high value of the diamond, the workers wouldn't have looked after it alone. Lu Wenjun explained, "It seems that I can't see the sawing completed today, and next time I have a chance, I'll pick you up again." ”

Yan Juan nodded regretfully, raised his wrist and looked at his watch: "Oops, I'm going to work!" ”

"Go to work...... Are you so nervous? Lu Wenjun muttered, reluctantly looking at the emptiness in his hand. He could only take the opportunity to shake her hand while Yan Wan's mind was elsewhere.

When Yan Juan got out of the car, he said embarrassedly: "Thank you, senior, you have made me gain knowledge again." However, today is too rushed, so I only invited you to eat a box of fast food, sorry. ”

"It's okay, next time we have a chance to eat together." Lu Wenjun's demeanor was still impeccable, and it wasn't until he looked at her hurried back that he couldn't help but smash his fist on the steering wheel. It's easy to find an excuse to get close to her, but there is no substantial progress.

She is so diligent, doesn't she know that this is pursuing her? A pair of eyes looked at those saws, and they didn't even give him a few minutes! For the first time, he suffered a setback.

Obviously, the last time I saw Yan Yixin send her to school, she was still sitting in the passenger seat and said a few words affectionately, looking reluctant. Is he Lu Wenjun inferior to Yan Yixin in any way?

Maybe Yan Juan really had to eat the head of the row in front of Old Lady Yan before he was willing to die? Lu Wenjun's heart moved, maybe he could put some eye medicine in front of Old Lady Yan in advance......

"Wow, you're in a great situation!" Lu Xiang walked into the store one step later than Yan Juan, and just saw Lu Wenjun's car leaving in the dust, and couldn't help but squeeze his eyebrows at Yan Juan in the locker room.

"Where do you think I'm going, I'm just going with them to see the sawn diamonds." Yan Juan hurriedly defended, "He has a girlfriend." ”

At this time, she realized that she was not jealous at all. Because, she has a more worthy of protection, right? Thinking like this, a gentle smile appeared on her face.

Throughout the afternoon, Yan Juan was still reminiscing about the scene she saw today: "If there is an experienced chisel, such a beautiful diamond can reduce the loss a little more." If the rough weighs 100 carats, you will lose at least 3 carats by sawing, which should be a large number, right? ”

"Hey, what are you babbling about!" Lu Xiang shook his hand in front of her eyes twice before he succeeded in pulling Yan Xuan's mind back.

"I'm thinking, the cleavage of diamonds and the cleavage of sawing."

"You're just stupid...... Lu Xiang rolled his eyes, "Even if you want to be a designer, you don't need to think about the internal structure of the material, right?" ”

"How could it not be? A good designer doesn't just need to be stylish. Regardless of processing or design, it is necessary to consider the size, color, hardness, refractive index, imperfections, and inclusions of the gemstone. Cleavage is especially important in diamonds, otherwise the fractures inside the diamond will be larger, and there is a high risk that the whole diamond will be scattered into chips. So, for high-end gemstones, designers must understand their internal structure. Still, I don't understand the ...... of diamond sawing."

"Okay, okay, these proper nouns, I hear my head big...... Let's wait for Manager Yan to come back, and then you can discuss it with him! No wonder you can sit for a long time and really don't understand what there is to discuss about these boring things! ”

It's been three days......
