What are the similarities shared by all crystals as they grow?

All crystals share a fundamental similarity in their orderly arrangement of atoms, ions, or molecules, which creates a highly structured, repeating pattern known as a lattice. As they grow, crystals typically exhibit a uniform geometric shape that reflects their internal symmetry and structure. Additionally, the growth process involves the accumulation of particles from the surrounding environment, leading to a distinct crystalline form characterized by specific angles and faces. Despite variations in composition, this orderly patterning and growth mechanism is a defining feature of all crystals.
