some minerals are very rare but the price isn't worth it, i suggest to increase 1/3 of the price of mineral
In all fairness Diamonds are not actually worth the big bucks they go for. Its all just a big scam. So maybe in stardew that scam doesnt exist :)It could make sense for the rarest minerals to sell for a higher price. I mean, a diamond sells for less than some artisan product at normal quality ^^'
