Create a square 1:1 finished wordmark graphic. Render only the exact text “JCN” in all capitals; no other words, numbers, or symbols. Make the word the sole focal point, centered and spanning about 84% of the canvas width and 48% of its height, with clear margins. Build each letter as a substantial, sharply cut, optically pure diamond-crystal form: precise flat table facets, crown facets, knife-edge girdle, and angled pavilion facets. Outline every letter with a continuous, highly polished shiny yellow-gold rim, visibly metallic and reflective, with bright warm-gold specular streaks. Keep the gold outline distinct from the clear crystal interior. Light the crystal with a hard overhead pinpoint spotlight: near-white brilliance on lit facets, deep blue-violet shadow facets, internal caustic corridors, and controlled red-to-violet spectral fire beams. Add crisp six-point star flares at selected letter apexes and facet junctions. Set the word against a deep midnight-navy-to-black gradient, like a dark jeweler’s vault; use generous uncluttered negative space and no white background. High-contrast gemstone facet rendering, ray-traced reflections and refraction, razor-sharp edges, polished metal, precise optical detail. Keep JCN immediately legible as a single custom-cut wordmark; do not add props, a setting, or extra ornament that competes with the letters.
