I'm not sure what you mean by "cristal" - try "crystal"-caves, all lower-case.
There a few caves dotted around the world that have been given the proper-noun, "Crystal Cave". A very quick internet look showed a "Crystal Caves" (pl) in Mexico, and in the singular, one in the USA and one in England. I daresay there are others, and the name presumably reflects them being rich incalcite formations.
They don't exist as a cave genera: caves are classified by the way they form but there is no "crystal cave" class.
Stalactites and stalagmites can be seen in caves, where they form over thousands of years due to mineral deposits from dripping water. Popular caves where you can see these formations include Carlsbad Caverns in the USA, Waitomo Caves in New Zealand, and the Cango Caves in South Africa.
Bioluminescent organisms, such as glowworms and certain types of fungi, can light up caves that are inaccessible to humans. These organisms emit a soft glow in the darkness, creating a beautiful natural light display in these unexplored caves.
Stalactites in caves are typically formed from minerals such as calcite or aragonite, which are deposited by dripping water containing dissolved minerals. These minerals precipitate out of the water over time, creating the elongated formations we see in caves.
Stalactites hang from the ceiling of caves, formed by the dripping of mineral-rich water. Stalagmites grow up from the floor of caves as the same mineral-rich water drips down. Over time, these formations can meet and grow together to create intricate cave structures.
Caves are usually natural formations (although some are man made) which bury deep into rock. Windows are man-made objects.
