Fortifying Stone

So if you are confused by my question, I mean the general social meaning of a semi-precious stone. Like some stones are thought to be calming, some thought to bring good luck, and so on.

What semi-precious stone would be best to represent a Fortifying Stone?

It has to be semi-precious, not precious, because the description of Fortifying Stones says that's what they are.

I'd go with hematite.

And that is clearly a great answer, so that's going into my notes.

Thank you for the help!

Would petrified wood count as a semi-precious stone? The symbolism for it making the subject more resistant to harm feels right, and it is exotic enough to beg to be magic.

Black Sapphire or Onyx... because it's what I always have on hand.

Some form of this has been a semi-precocious stone for ages- Amber :

from the wiki page:
'Amber is fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times.'

Agate and Jasper are also types of semi-precious stones that are both a form of petrified wood... or rather, petrified wood is a form of Jasper... but, whatever.
