Luxurious Yellow Diamond Engagement Ring

[Format] Professional e-commerce product main image, square 1:1, premium jewellery listing style with a moody black studio setting and glowing gold typography. [Colors] Near-black backdrop (#141416) deepening toward the corners, lifted by a subtle grey sheen behind the ring; the display type glows warm gold (#d9b45f) against white secondary lines; metallic silver and honey-yellow stones provide the only saturated colour. No frame border. [Layout] A centred vertical type stack fills the top third; below it the ring sits horizontally across the full width, shot slightly from above so the oval opening reads clearly, a soft contact shadow anchoring it to the dark ground. [Subject] No people. A slim silver-toned engagement ring with a high-polish finish, carrying a rectangular cushion-cut yellow diamond framed by a double halo — an inner ring of golden melee stones and an outer ring of tiny white diamonds — prong-set with delicate claws, rendered with studio sparkle and clean reflections. [Headline] Reading downward, centred: a petite white caps serif wordmark line; then "Original Custom Rings" in large glowing gold display serif; then a whisper-small gold caps tagline row; then "It Starts with Beauty, True to the Heart" in white serif between two short gold slash marks. [Mood] Understated elegance and romance; deep black expanse, warm gold light on type and gem, jewel-box calm that reads instantly at thumbnail size.
