Princess Norrell's eyes flashed and her cheeks turned red. It had been more than a hundred years. This was the first time in more than a hundred years that he looked at her seriously and gave herself a gift seriously...

She stared at Kristine blankly, watching him nod to her, the corners of his eyes slightly upward;

Seeing his own figure reflected in his pupils, shaking slightly, filling his eyes;

The only person looking at him was herself, without any sideways gaze. The box of jewelry next to him didn't even get the slightest look from him...

Her heartbeat became more and more violent. Suddenly she lowered her head and gave the Lord of Thunder a gentle push:

"Hurry up and continue your calculations. I won't disturb you anymore. Which reference book do you want? I'll find it for you..."

In the final analysis, whether she can be with him smoothly depends on whether her brother can recover. Her sister's qualifications are not as good as hers, and her brother is still young. As the eldest daughter, she must take responsibility -

—

Unless her brother can take over the throne, no matter what, she cannot let go of her responsibilities as a princess and follow her sweetheart to leave Everlasting Island.

Thinking about this, the princess's cheeks became increasingly red. She took a long breath, but calmed down, spread out her pen and paper, and continued to calculate. With Christine, she not only enjoyed the love, but also accompanied her.

He studies together:

The project that Kristine is working on has some sub-items that she helped research and calculate. As a half-step legend, she can already contribute to her brother's treatment!

The small study quickly became quiet.

The Lord of Thunder and Princess Norrell next to him each occupied a desk and devoted themselves to research. The tip of the pen brushed on the paper, and the moving tower spirit next to it occasionally made a buzzing sound.

The box of gems with a half-open lid shone quietly and lonely on the black velvet cushion, but no one looked at them again.

Gretel also wanted to devote himself to research quietly. However, he could not do this for the time being: Serira was spinning around, spinning around, holding the box of gems, with a face full of excitement...

"Oh, this diamond is so beautiful! Gretel, look, such a big diamond, so transparent, I can see your face through it! Hey, your face is so crooked, hahahaha!"

"That's the principle of a convex lens... After refraction, it will definitely be distorted. It's already very difficult to see..."

"This sapphire is so beautiful! It matches the color of my eyes very well! It would be very beautiful as a forehead ornament!"

"It's a pity that this sapphire cannot change color. Otherwise, it could turn into silver-blue or even silver. As the color of your eyes changes, it would be even more beautiful..."

"And this piece of emerald! Although it is a little lighter, cut it into small pieces, grind it into flowers, and string it together with mithril flowers to form a bracelet. How beautiful it would be!"

"Good guy, are you thinking about mithril now? The output of this thing is not large. Otherwise, let's change it to silver and engrave it with a magic circle to prevent blackening?"

"It's not impossible..."

Grete had no choice but to put down the research in his hands and accompany Cerela to appreciate all the gems one by one, one after another.

Well... should we say that the elves are really not stingy in this regard? Not only are they not stingy, they are also quite generous?

A box of gems, round, oval, drop-shaped, ranging from the size of a pigeon egg to the size of a thumb, filled to the brim.

There is no trick like layering the inside of the box and putting a few pills in each drawer!

Grete thought for a while. If he layered the velvet cushions in grids and placed one on each cushion, the volume occupied would quickly increase dozens of times.

At that time, the boxes for delivering gems will have to use traditional camphor wood suitcases. Or, if the grid is made larger, several camphor wood suitcases or a coffin will be needed to carry...

The picture was so beautiful that Grete shuddered subconsciously just by imagining it.

Serila, however, was still admiring the gems with joy. She turned over and over, picking up one, putting down another, picking up another, and then putting down another.

Just such a box, the size, clarity, and color are all top-notch. If you don't take into account the artificial factor, it is very eye-catching in Serrela's collection, and it can almost be regarded as a top-quality batch.

When she left Dragon Island and went out to travel, the gems she had accumulated in her hand were not as many as this, and they were not as good as this!

That is to say, after arriving in the Kingdom of the Eagle and the Kingdom of the Sun, I made a fortune and got a batch of good gems. Hey - I made a fortune again today!

There are so many gems, even if you don’t set them all up, just put them in a box and put them on the top of the pile of gold coins to look at them, you will be so happy!

"Gretel, what kind of jewelry should I use to set these gems? There are so many gems that I can't think of any new jewelry designs for a while!"

"Actually...you don't have to rush to install it..."

Grete put down the pen, picked up the pen again, put down the pen again, and picked up the pen again. He brushed and drew a vague sketch on the paper, erased it, and started drawing again:

"If these gems are cut, they will be more beautiful and the color will be brighter?"

The world already has gem cutting technology and so on.

Gretel could never forget that the divine crystal that the teacher brought back from the New World was cut into dozens of pieces under the watchful eyes of many magicians and nature priests.

Each elder of the Nature Religion took a piece of it as a source of power to activate natural magic and produce crops. Relying on the contribution of the indigenous god, the entire Kent Kingdom safely survived the famine.

Divine crystals can be cut, not to mention diamonds and gems? The question is, when cutting gems, how should they be cut?

Whether it is Nevis or Eternal Island, the craftsmanship of cutting gemstones cannot be said to be absent, but it is very primitive and backward. The gemstones Gretel has seen so far only have about ten facets at most...

A gem cut out like this cannot be said to be a gem, but it is still very, very far away from the gem in Gretel's concept.

From a gem inlaid in a hair crown, necklace, or ring, you can see the fire from eight feet away, and it is very, very, very far away...

"What? Cut?!"

Serila opened her eyes wide, holding the delicate pink gem in her hand, and subconsciously squeezed it back. Cut? Do you want to cut this gem into pieces?

If it is cut open, it will become smaller!

Make the gem she already got smaller?

no way!

"Ahem... Cerela, it's not what you think..."

Gretel wanted to explain, raised his hand, made two gestures, and then put it down slumped.

He probably has an idea of ​​how gems should be cut: round, square, oval, drop-shaped, and so on;

However, he has no idea how many cuts are required for each cutting method, what is the angle of each cut, and where to cut. It should be possible that different gemstones and different refractive indexes require different cutting methods...

…

Grete scratched his head, scratched his head, and scratched his head again. He simply put down his pen and rushed to the mage tower again to contact the other side of the ocean:

"Help me check, is there any relevant paper information on various gemstone cuts? Has anyone measured the refractive index of various gemstones?"

There are no papers related to cutting, and it is probably not popular these days. The gems in magic equipment are mainly large and complete, so that they can store more magic power.

Just for the sake of beauty and brightness, cutting off 1/3 or more of a gem is such a wasteful practice, at least in the current magic world, it is not yet popular...

Gretel sighed. It seemed that he had no choice but to do it himself...

"Ashu."

"Ashu!"

"Ashu, help me calculate it. The refractive index of a diamond is 417. How to cut it to get the best gloss... It's probably a shape like this. Please help me calculate it specifically..."

He took a stroke and drew a rough shape, with a flat surface on the top, a circle of outward-expanding slopes around it, and another circle of inward-contracting slopes at the bottom, finally converging into a sharp angle:

"I remember it seems that we need to cut 57 or 58 faces. You calculate where to cut and what angle to cut, so that the refracted light will be the most beautiful!"

"What, you want me to work again!" The oak stick was pulled out from the endless chromosome calculations. When he saw the new task, he immediately made a fuss:

"Boss, don't think that I don't know what you are thinking. If you chase Miss Serira and don't work hard yourself, you will leave it to me! - I am alone with a tree, and I don't even have a girlfriend.

You want me to count this!"

"What……"

Gretel was shocked:

"Ashu, you've learned too much! You're an oak tree, what kind of girlfriend do you want! You're a hermaphrodite! - Work quickly! Don't fool me here!"

The oak stick hummed, hummed. For a long time, after seeing Gretel unmoved, he finally drooped down the leaves dejectedly. In contrast, the fruits on the branches became brighter one by one.

The largest fruit at the top of the tree is larger than a grapefruit, and the shadow of a diamond gradually appears inside.

Constantly changing, there is constant light hitting it and then scattering, then adjusting the diamond cut surface, and then scattering again...

Buzz buzz, buzz buzz...

Inside the fruit, runes were flying, and a gentle mist rose above the leaves, covering the entire oak tree like smoke. Gretel waited patiently for a day, and finally waited for its calculation results:

"Boss! I figured it out! 57 cuts are the most beautiful!"

A projection quietly descended. Above, there was a shadow of a diamond suspended in the air, rotating slowly, beams of light coming from all directions, reflecting the stray fire on the diamond;

Below is a structural diagram, or three views. Each facet is marked with angles, lengths, proportions in detail...

Grete didn't know whether the calculation was correct or not, and he didn't even know if it had reached the limit.

But after a quick glance, he looked very similar to the advertising pictures he had seen in his previous life, "A Diamond Is Forever, A Diamond Is Forever"...

Grete took one from his collection of spell materials, found an excuse to get rid of Cerela, and secretly went to the elder Emmat. With a diamond in one hand and a cutting diagram in the other:

"Elder, please do me a favor..."

Three days later, a round diamond that was ten times more brilliant and a hundred times more beautiful than an ordinary octahedron diamond was held in Grete's hands and presented to Cerela in a precious and precious way.

"Serila, I give this to you..."

Before she finished speaking, the silver dragon girl screamed in joy and snatched the box containing the diamonds over.

She held the box in her hands and looked left and right, up and down, and suddenly touched it on her wrist. A translucent round object quietly emerged, melted, deformed, and was tightly connected with the diamond, and she wore it.

On fingers:

"Gretel! Does it look good?"

"...Diamond ring?"

Only then did Grete have the opportunity to finish the last word. Speaking of Serira, is the one you just used to set the diamond in the old scale you replaced?

"It's so beautiful! It's so beautiful! Gretel! Get another diamond, and I'll get you a ring too!"
Chapter completed!
