Applying to rubies (maybe amethysts)

PS: This idea can be used for both amethyst and ruby

I had an idea. Why not return the rubies and make use of them?
Rubies can serve as a finishing material, which further improves the armor in the game, but do not allow you to apply finishes for the beauty of this armor itself. 

Rubies can be found in the mine, or they can be crafted as a non-cerite ingot, and then it will be possible to craft an improvement finish.

The player will have a choice of what he wants more, stronger (good) armor or more beautiful.

There is already a non-cerite template that makes diamond armor non-cerite, but with the help of ruby and a new template, it will be possible to make the armor more strengthened.
