The dream tree located in crystal peak says "light refracted... power harnessed" so I guess the magical properties come from refracting light. In practical terms, I guess they store light and then for example emit it in the form of beams or use it for growth or power golems (energy basically?). Light is the power of Radiance and the statue of Radiance is at the peak of the mountain so there's that connection as well. Perhaps the overgrowing of crystals and their subsequent contamination of living beings was caused/stimulated by Radiance somehow. As far as that contamination goes, it behaves not unlike the infection we see in other parts of Hallownest.

When you meet Quirrel on Crystal Peak he says something that the crystals were harnessed for their power that is similar to Soul that the bugs in Soul Sanctum were experimenting with. He says it was a power "less deadly" (or was it more deadly? that dialogue for some reason is not on wiki page for Quirrel)
