Create a square typographic key art / wordmark featuring exactly one text string: “RADIANT”. The word is centered and spans 82% of the canvas width, with generous dark negative space above and below. Render “RADIANT” in custom all-caps wide display lettering carved from optically pure, colorless gemstone crystal. Each glyph has a flat polished table facet, small crown facets, a crisp widest girdle edge, and deep angular pavilion facets; every plane junction is a razor-sharp knife edge. Use clean, evenly spaced letterforms with substantial strokes and slightly condensed proportions so the full word reads immediately. Set the crystal letters against a deep midnight-navy-to-black gradient, like a jeweler’s display vault. A single hard overhead pinpoint spotlight strikes the top tables and crown edges: illuminated facets return near-white light, while lower facets fall into saturated deep blue-violet and blue-black shadow. Show bright internal caustic corridors running through the strokes, total internal reflections, and precise high-contrast scintillation across each letter. Place sharp six-point star sparkle flares at selected apexes and corners, especially the A peak, R bowl edge, and T top corners. From only a few crown facets, project thin, controlled spectral rainbow fire beams—red through violet—into the surrounding darkness. Keep every beam crisp and geometric, never foggy. No extra words, no badges, no objects, no people, no border. Ultra-detailed ray-traced gemstone optics, polished diamond surfaces, black negative space, 8k product-render clarity.
