Once it’s made, it isn’t as sensitive. The crystals themselves are stable. It’s just growing them from cooling the melted material in a particular way might be sensitive to other forces while it’s being made.
Think about how big diamonds need nearly perfect conditions to form underground. But once they’re formed, they can be taken out and they will keep their crystalline structure even outside of the conditions in which they were formed.
Even growing salt crystals from salt water can be super sensitive to slightly imperfect conditions. But a block of salt crystal, once formed, is pretty durable.
