Luxury Pear-Shaped Diamond Ring on Rose Gold Band

Generate a hyper-realistic image of a luxurious pear-shaped diamond ring set in rose gold, prominently displayed on a rugged, dark rock surface with subtle orange undertones, against a blurred, dark blue-gray background that gradually fades to black, capturing the intricate details of the gemstone and the metallic sheen of the band, with soft, natural lighting that accentuates the crystal clarity and faceting of the diamond, and realistic shadows that add depth to the composition, reminiscent of high-end jewelry editorial photography.
