Create a finished vertical 60th wedding anniversary card, 3:4. Deep midnight-navy-to-black jeweler’s vault gradient with abundant clean negative space and no white background. At top, small spaced engraved-silver sans serif text: “A DIAMOND ANNIVERSARY”. Centered across 58% of the card, the exact headline “Sixty Years” on two balanced lines, with “Sixty” above “Years”. Build every letter as flawless precision gemstone crystal using brilliant-cut diamond anatomy: polished flat table facets, angular crown and star facets, sharp widest girdle edge, deep pavilion planes. Razor-sharp facet seams catch intense white specular spikes; table facets return near-white light, lower planes fall into deep blue-violet and blue-black shadow. Visible internal caustic corridors run through each letter. Narrow red-orange-yellow-green-blue-violet spectral fire beams break outward from selected crown facets, controlled and sparse. Place crisp six-point star sparkle flares at the highest apexes, especially S, Y and the terminal s. Below the title, a pair of interlocked platinum rings with small round-cut diamond settings floats at center, partly framed by the descending crystal light beams; ray-traced metal reflections and pinpoint diamond scintillation. Bottom center in restrained small silver serif: “16 SEPTEMBER 2026”, then “WITH LOVE, MARGARET & THOMAS”. Composition: formal centered card, title is the dominant object; rings provide a distinct hero prop beneath it; generous dark margins. Hard overhead gemological spotlight, high contrast, physically accurate ray-traced refraction, dispersion, internal reflection and caustics, crisp focus, no extra words, no watermark.
