Teacher is a bit... embarrassing, so. Huh, just leave it as it is...?
Um, then I'll explain magic stones.
From an item shop owner's point of view, they're the standard bestseller. I think most shops would see them the same way.
But from an appraiser's point of view, magic stones are very deep. So deep, in fact, that many appraisers say they're difficult, so our evaluations aren't exactly uniform... Ah, yes, I understand. Then this time, I'll explain them as an appraiser.
The value of a magic stone can be broadly divided into two categories: practical or decorative.
That's a commercial classification, but the appraisal standards barely change, so as an appraiser I don't really separate them. Something with excellent practicality also tends to be highly valuable as a decorative piece, that sort of thing.
Eh? Yes, that... magic stones used as ornaments being absurdly expensive? That's an item shop matter, but when it comes to pricing products, decorative value is still what matters most, so...
I-it's priced according to market value, so it's not a rip-off.
I'll continue as an appraiser!
The value of a magic stone is, above all, determined by its quality. Think of this quality as the amount of mana it contains.
Yes, that's right. This also applies to decorative value.
The amount of mana can be judged from various aspects of the magic stone.
One is its shape. The closer it is to a perfect sphere, the greater the amount it can "potentially" contain.
Since mining can't produce naturally spherical stones, this only applies to ones brought in from monsters by adventurers.
There are also cases where the capacity is large, but the actual mana is low. In that case, its value is lower than one with the same capacity, but if it seems like the mana can be replenished, it may actually fetch a higher price.
Yes, size doesn't matter much.
Next is color. The more vivid it is, the more mana it contains.
However, this is the part that gives appraisers the most trouble, or rather, the part where we have to be the most careful...
Magic stones that contain only one attribute are actually quite rare. That shows up as muddiness in the color.
It may look cloudy, but all that means is that several attributes are mixed evenly, while the actual amount of mana is high.
Ah, is this only an explanation of value this time?
Then, yes, a vivid single-attribute color is the most valuable.
It's easier to use practically, and it's also very popular as a decorative piece.
As for magic stones obtained through mining, there's also the original ore.
This is kind of a review of the two points I just mentioned, is that okay?
Y-yes! Then I'll explain.
In mining terms, a magic stone is "ore that has stored mana."
You can crush it and use it as fertilizer, or grind it into a perfect sphere to artificially increase its mana capacity.
That's right. It's quite inferior to naturally formed stones, but even when shaped into a perfect sphere by human hands, it still works.
However, what increases is only the amount it can "potentially" contain, so it's meaningless unless it's the type that can be replenished with mana... Still, this is the most common type of magic stone in everyday life.
They're usually used that way, but depending on the original ore, there can be differences.
Magic stones made from precious metals, the so-called gemstones, are... amazing. In terms of rarity, and in terms of mana assets.
Both their mana amount and their potential capacity are enormous, and each type of gemstone has a guaranteed single attribute.
In other words, the color is top-tier too, and they're extremely easy to process, so they almost certainly become ornaments.
If you process them into something other than a perfect sphere, the mana decreases a little or the color changes slightly. But their design value goes up, so I guess it balances out. After that, it's just a matter of the owner's preference.
Then I'll summarize.
The quality of a magic stone is judged by shape and color. The more perfectly round it is, and the more vivid its color, the higher its quality.
