金色天鹅绒垫上的奢华钻石特写

Place the diamond on a velvet cushion. The entire scene is covered in warm and soft golden tones, with natural light and shadows interwoven, a blurred golden background, creative composition, and an overall luxurious and elegant look. This is perfect for high-end jewelry photography, with a low angle, close-up shots of the diamond, 8K resolution, Unreal Engine, realistic rendering, fashion, depth of field, and ultra-high definition. --ar 3:2 --q 2 --v 5.1 --s 750 --style raw
