The results of the Ancient Jewel Plant came out as soon as Elaina had it verified and just like the precious stones that are mined normally, the Ancient Jewel Plant's fruits are all genuine jewels and are in high quality as well without it being processed just yet.
In the end, Elaina managed to sell them at a much higher price than their regular prices. It's not enough for Elaina to be called rich after selling all of those precious stones but they are just great additions to Elaina's funds and that is the most important thing. It would have to fetch a bigger price if it was formed into a piece of jewelry, but no one from them is capable of doing that and Julia who can make a few trinkets like a necklace or a ring is not that great at making good designs for jewelry to get a good and high price so it ended up being not too well and they instead sold it just like that.
