Emerald Space Jewels

An ethereal space scene showcasing levitating, multifaceted crystals with glowing, emerald green cores. These crystals are set against a backdrop of swirling galaxies and nebulae in deep purples, blues, and greens. Scattered among them are smaller, opalescent shapes with delicate rings. Above, a bright, comet-like streak with a tail of orange and yellow lights up the scene. The foreground is defined by dark, rugged terrain that adds contrast to the luminous elements.
