How do crystals form?
Crystals form when atoms or molecules settle into a regular, repeating arrangement as a substance solidifies — as molten rock cools, as water evaporates from a salty solution, or as vapour freezes. Given time and stable conditions, this ordered growth produces the flat faces and geometric shapes crystals are known for.
Why are crystals clear and geometric?
Their clarity and sharp shapes come from the highly ordered way their atoms are stacked. Because the internal pattern repeats evenly in every direction, the outer surfaces grow as flat faces meeting at consistent angles, and light can pass cleanly through a well-formed, defect-free crystal, giving it a transparent appearance.
