Photorealistic image of a transparent crystal cube floating on the void it appears as if it is on space floating with nothing arround it. The cube is slightly tilted, showing three faces. Edges of the cube are slightly rounded and with a rainbow prismatic glowing, refracting light into vibrant rainbow colors. The cube's faces are mostly transparent with a subtle, cloudy translucence. Interior of the cube shows faint, misty distortions. Brilliant light refractions behind the cube create intense rainbow-colored flares along the edges and corners. High-contrast lighting emphasizes the cube's three-dimensional form. Ultra-sharp focus on the cube, with crisp details. No visible shadows or reflections. The cube appears to be levitating. Hyper-realistic style with attention to the play of light through the crystalline structure.
