ساخت مکعب شیشه ای رنگین کمانی سه بعدی

Create a high-end 3D product render of a single transparent glass cube with sharp geometric edges and a slightly irregular handmade shape. The cube has glossy, crystal-clear surfaces with vivid iridescent reflections in blue, red, purple, orange, and white. Add a small, clean white "ASC." logo centered on the top surface. Place the cube alone against a pure black background with no additional objects. Use dramatic studio lighting, strong edge highlights, realistic glass refraction, internal reflections, subtle chromatic dispersion, deep contrast, centered composition, three-quarter top view, premium advertising photography, ultra-detailed, photorealistic, square image. Keep the logo legible and the cube fully visible.
