Three years after D Genesis Dungeon

The stone was brought in by staff who had been urgently requested by JDA staff.

"Oh, what's that. A necklace with a rosary-style design?" "Oh, Mr. Rokujo. I was asked to do an appraisal. It seems to be an item that came out of the dungeon, but removing the stone is NG." Then, how about that?

Rokujo wheat is a hardcore mineral enthusiast who hates being called a mineral girl. While gem appraisal was their main job, the people who worked there tended to be more or less like that, but her geek soul could be pulled by her colleagues.

◇◇◇◇◇◇◇◇

That was June 8, 1997, which I will never forget.

The Tokyo International Mineral Fair, which was frustrated by the father of a fossil enthusiast, displayed a very rare fossil of a fetus in the eggshell just before the hatching of a Terizinosaurus. It seems like my father just used wheat to see it, but the wheat, which had just arrived in elementary school, was getting nervous when he went out to dad on Sunday.

The fossils in question were nothing more than beautiful, as they were just messed-up bones stuffed into egg-shaped stones, so wheat felt nothing. With his father who was crazy about it, the wheat that was going around the venue was drowned in the whole body skeleton of Erasmosaurus from Morocco, running away and lost. Then, while worried, he came across it while searching for his father.

"beautiful……"

In retrospect, it was a not-so-unusual crystal cluster that was a little bit better. But in the eyes of the wheat then, it seemed like a wonderful treasure in wonderland.

Wheat was taken out of the pocket 500 yen coin in my pocket, but it wasn't very affordable. At that time, a gentle, droopy uncle who was watching it all the time talked.

"Jojo. Did you like the crystal?" "Let's go." "Hey, the glittering guy there."

Wheat saw it and nodded.

"Well, how about this? I saved it because it's small but well-formed."

Having said that, he picked up a small cluster that would ride on a 100-yen coin, as if he had just taught the treasure he had seen before.

Wheat liked it at a glance.

"Can you buy it now ...?"

The uncle told me that the 500-yen coin that he was holding was squeezed, and he said that he was nodded enough.

"This crystal is fragile because it's a baby. Don't hit it."

He fixed it in a small case, called a micromount, with a transparent lid and gently handed it to the wheat. The wheat was gladly held up over the light, and in some places a rainbow was seen. It seemed like an entrance that invited her into a dream world.

"Do you like it?"

In response to his words, Wheat smiled with a full smile and nodded vigorously and said, "Thank you!" She then gladly jumped into the bottomless swamp.

After that, my father came in a hurry to search for her, and was angry that I couldn't do it alone because it was dangerous, but I thought it was a little unreasonable.

The uncle at that time was the owner of a mineral shop in Okachimachi. Now that she is about to be an old man, she has been dating her like a friend ever since.

"It's just a quick simplicity appraisal. It's a rough estimate because we don't issue a formal appraisal. If you don't return to the lab, there's no Raman or photoluminescence."

Photoluminescence measurement is a device that measures composition and crystallinity, and Raman spectroscopy is a device that can perform various optical tests. Its main use is for semiconductor development, but it is also used for stone analysis. It's quite expensive and can't be bought.

At this point, where the main focus is on simple checks, at best, refractometers are used for micro and dichroic and UV multi.

A microscope is essentially a microscope, and a dichroscope is a simple tool for examining the pleochroism of a birefringent colored stone. The UV multiscope is a long-wave and short-wave ultraviolet light for viewing fluorescence, and the refractometer is, as the name implies, a device that measures the refractive index.

"And I don't know how the stones are sticking together. I'm not confident I'll get them back if I remove them."

Wheat wore white gloves, picked it up, and looked at the connection, but with a slight dip in the visible area, he wasn't sure how to fix it. Then he touched the surface and moved his finger as if stroking, and sighed with satisfaction. A briolette cut that makes you feel the hands of a skilled craftsman.

"I like the cut. It looks like an antique."

Pear-Shaped Brilliant is also a beautiful teardrop-shaped cut with a calculated refractive index, but the briolette, which is finely faceted in all directions, has a unique atmosphere like an estate jewelry (* 1).

"At first I thought it was aquamarine." "It's not. The refractive index is totally different."

Wheat said while looking at the stone with a loupe.

"The refractive index was almost the same as that of corundum-" "It has birefringence (* 2). It is not sapphire, nor is it cyanite ...? What is the fluorescence (* 3)?" "Vivid blue, Did it? "" Blue? "

Wheat involuntarily looked away from the loupe. The remaining possibility is that the zircon has turned light blue, but its fluorescence will be yellow or orange.

"If it's orange, the wave breeze didn't stand ..." "Information up to now, the ultimate is this flashy fire-"

Make the stone transparent to light while changing the angle.

"--Maybe Benitoite?" "From the figures, it's almost the same." "Huh. I haven't heard that Benitoite was artificially synthesized ..." "Because it wasn't."

The man who was assessing shrugged.

"Is there 10ct?"

Wheat looked at the stone that he had placed on the case at hand.

"It's definitely bigger than Smithsonian's"

Benitoite has few large stones of gem quality. Therefore, 1 ct (0.2 g) is considered to be sufficiently large. The facet-cut, perhaps the world's largest stone, was at the Smithsonian Institution, measuring 7.7 ct.

"I'd like to take it to the lab a bit ..." "I can't do it. It's almost time to return it." "Extend it."

If you don't take the stones from customers and return them at the scheduled date and time, you will have serious credit problems. Wheat was looking at the stone, swiftly and reluctantly.

"But ... what kind of stones do dungeons come out of?" "In the published material, mineral resources appear in 20 to 79 layers, or" "How can I go there?" Shall I? ”“ Hah?

Although it was usual for the wheat to fly, the man laughed and cheated that this was a joke. But the wheat was very serious at this time.

◇◇◇◇◇◇◇◇

"Benitoite?" "Yes. You said it was aquamarine, but the refractive index was quite different."

Naruse said while watching the tablet displaying the survey results.

"From the refractive index, the degree of dispersion, the specific gravity, and the fluorescence under UV light, it is likely to be a bryolite-cut, benitoite." "Why?" However, large stones are unusual, and 1 ct is said to be large enough, and at the top, it seems to be about 10 ct. "

It didn't come easily even if said to be 10ct. After all, it is 2g in terms of grams. Naruse added an explanation to my reluctant reply.

"Okay, Mr. Yoshimura. The largest faceted face in Benitoite is in Smithsonian, but that's 7.7 ct?"

In short, it is the largest stone in the world that can be said to be impossible, and its transparency makes it very valuable. It seems to be frustrated to determine that with a simple appraisal. So, maybe, what?

"I had a request to have a detailed appraisal." "No, it's good because it's a hassle. I just thought that if I knew the stone, I would know the right way to care."

Because there are soft stones and stones that fade when exposed to sunlight.

"What's the sign of the example than that?"

After muttering that, Naruse replied with a sad face.

"What happened?" "I couldn't get the opponent from the beginning, even to joke me."

Yeah, well. In the inscription from the dungeon, is there a sign of a man who died in an accident three years ago? HAHAHA, what mystery mystery?

"I also looked at Dr. Tyler ..."

There, his public career was written. The title lists the titles of many organizations.

AIP member APS member KLI member AGU member ……

"I know the American Institute of Physics and the American Physical Society, but what is KLI?" "Is it immediately possible to come up with the Korea Labor Institute?"

"In the end, I was director of the Particle Physics Laboratory in Nevada." "Is there an accident that happened there?" "It was recorded that it was during an extra dimension verification experiment." "So the autograph was ..." "Unfortunately I couldn't find it."

If I could find it, I wanted to compare it with the letters in the inscription, but couldn't help it.

"So, what is the content of the inscription after all?" I also saw it, but it seems to be a character that I have never seen. ''

Certainly, the letters used in the first and second half are clearly different. I said while checking the picture on the tablet.

"What's in the first half?" It's like the last page of the wanderers, it's close to a so-called postscript or imprint ... " I think it's a book. "

Miyoshi caught his mouth while replacing it with fresh tea.

"By the way, it's the 13th Ramanujan prime, senior."

Again, when I thought so, the front doorbell rang.

After seeing the video, Miyoshi said, "Are you? Mr. Saito?"

"Are you with Mr. Tsurugi?"

Miyoshi said so while laughing.

◇◇◇◇◇◇◇◇

"Chiss" "What happened? It's unusual." "It's almost time for the drool to run out, so I'm gonna get it when I have a little time." "Okay"

With that in mind, she bowed to Naruse and sat down in a chair opposite. On the desk was left a tablet with an inscription displayed, but nothing special to keep it secret.

After a while, he returned with a half-dozen bottles prepared by Miyoshi and said, looking at the tablet image.

"What is this" tell your fellow earth people? "

When we heard it, we all shouted in our hearts, didn't we?

((((What, what?!?))))
