Luxury Yellow Diamond Ring E-Commerce Showcase

[Format] Professional e-commerce product main image, square 1:1, high-jewellery showcase style with dramatic dark lighting and refined serif typography. [Colors] Background is a deep charcoal-black, near #1a1a1a, with a soft dark vignette and a faint reflective floor. Accents are polished white gold on the ring, a fancy yellow centre diamond surrounded by a white-diamond halo, warm gold serif headline type, and small white letterspaced text. No frame border. [Layout] A small white letterspaced brand wordmark sits at the top centre. The gold headline follows beneath it, with a tiny caption line under. A short white line with slashes sits mid-frame. The ring occupies the lower half, centred and shot slightly from above so its profile and halo catch the key light, with a whisper of reflection beneath. [Subject] A white-gold solitaire ring with a cushion-cut fancy yellow diamond at its centre, framed by a pavé halo of small white diamonds and set on a slim polished band, presented at a three-quarter tilt; crisp specular highlights and dark-luxury contrast. No people. [Headline] Top: a small white letterspaced brand wordmark. Beneath: "Original Custom Rings" in very heavy gold serif caps. Under it a tiny letterspaced caption line in faint gold. Mid-frame, a modest white line between two slashes: "Won at First Sight, True to the Heart" in light caps. [Mood] Quiet, precious and boutique-dark; single-jewellery drama under a spotlight, gold serif elegance and jewel-box minimalism.
