Diamonds are clear and see-through yet they are made of highly pressurized carbon which if you see in its unpressurized state looks like black powder or a handful of ash, What happens to cause it to become see-through like that. For that matter the same question for sand and silica into glass.

It’s often-times easier for light to pass through compact crystals than loose particles.

Ice cubes are transparent because they’re compact crystals while snow isn’t because it’s loose particles
