Rainbow refraction

Create a 3D rendering of a diamond that is reflecting the wide, diffused glow of a powerful rainbow LED light. The light should not appear as a direct beam; instead, it spreads broadly across the diamond. The scene takes place in a dark environment, with the light shining down at a 60-degree angle from above.The diamond should refract and reflect the light realistically, with the facets behaving as they naturally would. Use a classic “movie-style” diamond cut, positioned upright on its bottom tip without any tilt.You should not show the light source or the rainbow beam itself—only the resulting refracted rainbow patterns cast onto the floor. The diamond should have a slight opaqueness, giving it a subtly duller, more ambient and atmospheric glow. Rotate the diamond in place.
