I've been playing Stardew Valley on my Xbox One for about a week or so, and I can't seem to get earth crystals. I see them commonly in the mines, but I have no clue as to how to actually get them as an item. I cant seem to use any of my tools on them (the same goes for quartz). I don't desperately need them, but it'd be nice to know how to get them, and if anyone knows how to please let me know.
Just pick them up like you would pick up a ripe vegetable on your farm.
They are found in the mines in level 1 to 50. you pick them up by clicking A on them or the green button while facing them.
