Cracked Crystal 4

A luminous, crystalline geometric shape with nested curved rectangular forms rendered in translucent green tones against a deep black background. The primary shape consists of three concentric rounded rectangular outlines that create a flowing, wave-like pattern. The outermost and middle layers exhibit a bright, glowing mint-green color (#3ca37a tinted) with faceted crystal surface details that refract light, creating prismatic highlights and subtle rainbow-like edge effects. The innermost layer remains dark, creating negative space that emphasizes the hollow structure. A soft, diffused glow emanates from the crystalline surfaces, particularly bright at the upper-left edge where light appears to strike the faceted geometry. The crystal material shows high specularity with bright white highlights (#c8dbfa fresnel color) concentrated on the upper portions, while darker shadowed areas appear on the lower sections. The background features subtle blob-like atmospheric distortion in very dark green tones (#08120e to #123323), creating depth and subtle environmental lighting. A god-rays effect with dark green rays (#0a3a28) radiates from the center, adding volumetric depth. The overall mood is ethereal and technological, with a cool, calming energy enhanced by the glowing green luminescence and crystalline material properties.
