Garnet implied in Reformed that Gems, not just Amy, can regenerate in a very short amount of time if they want to, coversely, they can do it for a very long amount of time. Along with that thought, Rebecca herself said that the Gems can form new clothes if they want to, after regeneration or just stay the same. And seeing Amethyst practically only did a palette swap, it's not that hard to think why her regeneration was fast.
