All These Minerals/Gems?

[Reaptor]

I got all these crazy monster loot, minerals, and gems. Ive donated all I could to "discover" them. What do I do with them now? Sell them? Gift them?
I just got like weird stuff like Fire Crystal, Fire Opal, Jade, Thunder Egg. Any ideas?

Some have recipes like you can find here otherwise you can sell them:

Artifacts generally don't make good gifts. Gems do though. Minerals don't. The difference? Not sure.

I usually just sell them. You can look up villager likes on the Stardew Valley wiki, as well as universal likes/dislikes, etc.

There is no need for blacksmith and armory so the five ore with the farming gear
and the rest go for the money!

this part has set with animals cross
which item are always useless...

some of them can go towards a junimo gift that you have to unlock by doing junimo tasks

I took everyones advice and sold them. I was sitting on 27,000g in gems.
