A whimsical, almost fairytale-like hidden cove where the sand is made of glittering amethyst crystal

A whimsical, almost fairytale-like hidden cove where the sand is made of glittering amethyst crystals and the gentle waves are a soft lavender hue. Giant, iridescent seashells dot the shoreline, and a small, crystal-clear pool reflects a sky filled with two moons. The style is a vibrant, high-fantasy digital illustration with surreal elements. --ar 3:2 --v 8
