"Generate a high-quality rendering of a luxurious marble rectangular tray featuring four round grooves, adorned with gold metal decorations. The marble should have an elegant, polished finish, showcasing its natural veining and texture. The gold metal decorations should add a touch of opulence and sophistication to the design. The tray should be placed on a clean white background to highlight its upscale and refined aesthetic. The grooves should be evenly spaced and seamlessly integrated into the tray's surface, enhancing both its functionality and visual appeal. This rendering should capture the tray's luxurious and modern elegance." --ar 4:3
