1.17 Crystal quartz block/biome

Take a regular quartz block and smelt it (blast furnace could work), this would cause the block to become a column of semi-translucent crystal. This could glow, and occur naturally in the new caves in large cluster block spires that can grow in any direction(like how logs work), these can both be found in any biome in few quantities and have it's own biome in huge quantities. Think the giant crystal caves in Mexico for an idea of how this would look.
