The two most popular methods for man-made diamonds are HPHT and CVD.

Among them, HPHT stands for high-pressure and high-temperature, and CVD stands for chemical vapor deposition. ‘

Although man-made diamonds are recognized as diamonds by the GIA (called the Gemological Institute of America in the 21st century, abbreviated as GIA), the world's most recognized authority on gemstones, the GIA report will indicate HPHT or CVD, and man-made diamonds are different from natural diamonds in terms of nature and structure, so the general public believes that natural diamonds can be considered real diamonds.

That's why Zuo Jiuning put forward this hypothesis.

However, these two mainstream methods can only produce colorless diamonds, yellow diamonds, brown diamonds, blue diamonds, green diamonds and orange diamonds, not pink diamonds.

Yellow diamonds are exposed to nitrogen over a hundred years of formation, while blue diamonds are colored by boron, purple diamonds are caused by hydrogen, and green diamonds are due to radiation.

The cause of pink diamond color is still questionable, and scientific evidence shows that the color of natural pink diamonds is caused by the distortion of the crystal lattice, so pink diamonds are one of the most difficult colored diamonds to be artificially made.

Irradiation has been used to make pink diamonds since the beginning of the 21st century, but because of its high cost and the continuous development of new technologies, mainstream artificial diamond manufacturers have almost stopped using this technology to make pink diamonds, and only a few laboratories that have conducted separate research, such as the branch family of the original family of Zuo Jiuning, will study this technology.

The advantage of light osmosis technology is that it can create large pink diamonds.

However, no matter which method is used to create a diamond artificially, there will basically be a fine sediment in the diamond, and the method of creating a pink diamond is no exception.

However, this subtle precipitation is generally not visible to the naked eye...

"Just use a magnifying glass, right?" said sake, "You remembered when you talked about precipitation... I have seen in a 21st century literature that this method of making pink diamonds using light osmosis is said to be visible under a high magnification glass. ”

"Not bad, sake. You can even find documents from 1,000 years ago. Zuo Jiuning smiled and shook the wine glass in her hand to the sake in greetings, of course she knew that with the strength of the sake family, she could find it, but it was not easy to find such a remote knowledge of the literature.

But how did the design team of such a remote knowledge game company know? This is a question worth investigating, Zuo Jiuning thought to himself.

"Very well, sake, you finally provided some useful information. Drunken Dream nodded, then asked, "But, sake, did you realize a problem?"

"What's the problem?"

The answer to the sake was a drunken dream smirk: "Ask Von, you're not as good as him!"

Sake wondered, "Von?"

"I!we!no!have!put!big!mirror!" Von replied loudly, realizing the problem after Sake said he was going to use a magnifying glass, but instead of sending the team channel, he directly sued Sù for drunken death.

“Well… Then there is no way..."Sake said deflatedly.

Everyone was silent for a while, and the absence of a magnifying glass was indeed a matter of sternness.

Eventually, it was Bloodbone who broke the silence again: "Can we find something instead of a magnifying glass?"

The other four replied in seconds: "Go on, be specific." ”

"Well, it's just an idea...", Bloodbone replied again embarrassedly with the same answer.

Crowd: "..."

The good thing about the situation of blood bones is that in the case of no idea, it is a slow half-beat blind guess and a sharp guess, and the guess is right, to put it bluntly, it is a blind cat that hits a dead mouse.

Since he was really just guessing, he didn't have the next train of thought at all.

Last time, it was Zuo Jiuning who thought of the possibility of artificial diamonds from his thoughts, and this time it was Von who had an idea: "There you, how about a big drop of water on the gem?"

"Brilliant, Von!" the drunken dreamer applauded, "You haven't studied for so many years!"

Zuo Jiuning also understood what Von meant, and nodded in agreement: "Welldone!GoVon!"

"Von's approach is really creative. Sake, who also understands it, agrees.

"What?" only Bloodbone couldn't keep up with Von's leaping mind.

"Hahaha, blood bones... I have a mention..."Von laughed and pretended to look at the blood bones mysteriously, deliberately lengthening the appetite of the blood bones.

Blood bones: "What mention yì?"

"Let's go back to the furnace and practice again!ahhahahaha!" Zuo Yuning tacitly took over the conversation, laughing and unceremoniously sprinkling salt on the wound of blood and bones.

"Hahaha, Sister Dionysus, you're too direct!" Von laughed breathlessly.

"Hey, you two!" protested Bloodbones.

Sake hits the round: "It's not good to be drunk to death, it's not good to waste any more time..."

"Hahaha, forget it..."Drunken Dream was laughing himself, so instead of stopping Von and Zuo Jiuning, he said to Sake, "Sake, although the elm head of the blood bone will probably never be opened, you should explain it to him." ”

Although the drunken dream speed up the progress, it is still a mending knife for the poisonous tongue, and at the same time makes Von and Zuojiu smile even more.

Sake couldn't beat the round, so he had to go down the steps given by Drunken Death Dream to be responsible for the explanation: "Blood bones, you see, didn't the middle school textbook mention it? A bottle of water left in the sun can cause a fire?"

"It's mentioned. Blood Bone replied affirmatively, "Because at a certain angle, a bottle of mineral water will have a converging effect on sunlight... I know all this, sowhat?"

"Hahaha!!" drunk to death, Von and Zuojiu laughed even more.

“so… Like a bottle of water, a drop of water will have a converging effect on the light, like a convex lens. "The sake is also a little unbearable," and the magnifying glass is a convex lens, which has a converging effect on light. So a drop of water can act as a magnifying glass if it remains like a droplet. ”

Bloodbone nodded in understanding, then remembered that sake couldn't see, and then replied, "I understand." ”

"Then let's start the identification!The task is mine, I'm going to see if there's any sediment in the gem!" Von excitedly asked.

“OK。 Drunken Dream nodded in agreement, "Then you can do the appraisal! ”

"Great!!" Von replied happily, "I'm so drunk with you!"

…

ps:I have to say first,47 and 48 are the harmonious words are easy / face / mask,A few days ago it has been uploaded and modified.,I really don't understand why this is a harmonious word...

Then about the specific operating principle of the method of artificially creating diamonds, there is it on Wikipedia, because it is relatively long, I will not translate, if you are interested, Google "SyntheticDiamondWiki".

And the light osmosis technology (irradiation) I don't know how to translate the most appropriate, so marked in English, the specific principle of operation of this method I didn't find on the wiki, but there are still websites introduced in English, the same is too long to translate, if you are interested, please Google "Irradiationsyntheticdiamond" by yourself.
