Rare new biome, the Crystal Cave!

So, welcome to my idea. Today we'll talk about crystal caves and their not so many uses other then decoration! Crystal Caves spawn very rarely. They contain stalagmites of a new block called "Solidified Crystal". They have color variants, with them being called purple, pink, red and teal. These crystals give off a faint glow, and drop a new material called "[Color] Crystal Shard". You can craft these in a 4 by 4 to make its solidified version, or use them to make "Glowing [Color] Dye". You can use this to make the dyed items glow as the glow squid with their respective color! These solidified crystals also have a new type of pointed dripstone called "Pointed [Color] Crystal". These act just like dripstone, but instead of fully disappearing when they hit the ground, they turn into "[Color] Crystal Shard]. They can only be mined to get their true block with silk touch. In these caves, geodes also spawn much more commonly. Thank you for reading, goodbye!
