Luxury Yellow Diamond Solitaire Ring

[Format] Professional e-commerce product main image, square 1:1, high-end jewellery advertising style, dark and luxurious with a single radiant hero gem. [Colors] Deep charcoal-to-black gradient background (#101013 to #1e1e22) with a soft vignette glow behind the product; headline type in luminous gold (#e6c46f) with white supporting lines; the yellow diamond and polished silver band carry the main accents. No frame border. [Layout] All typography stacked across the upper half, centre-aligned in a slim column; the product dominates the lower two-thirds at large scale, angled in three-quarter view, with a faint mirror reflection beneath it. [Subject] No people. A polished white-gold solitaire ring photographed at a low hero angle, the slender band sweeping horizontally across the frame, set with a large cushion-cut canary-yellow diamond wrapped in a pave halo of small yellow stones and a fine outer rim of white diamonds; glossy metal, crisp specular highlights. [Headline] Top centre: a small letterspaced white serif caps line, then the main title "Original Custom Rings" in glowing gold serif with a soft vertical gradient. Beneath it a hairline gold rule with tiny gold caps, then a small white serif line "Beauty at First Sight, Loyal at Heart" flanked by thin gold slashes. [Mood] Quiet luxury boutique showcase; black velvet ground, one radiant gold stone, refined serif type, generous negative space.
