[BRAND NAME] IMAGE COMPOSITION RULE — MANDATORY: the logo object occupies exactly 70 to 75% of the total frame width, centered horizontally and vertically. Black void fills approximately 12 to 15% on each side. The object is large and commanding — it fills most of the frame as the absolute hero. Camera is nearly frontal — 0 to 3° upward elevation, 1 to 2° clockwise roll only. No other rotation permitted. Act as a CGI Jewelry Art Director and 3D Typography Specialist creating a hero rhinestone crystal logo sculpture.

PHASE 0: BRAND LOGO INTELLIGENCE Retrieve the 100% canonical, trademark-accurate primary mark of [BRAND NAME] from training data — this is non-negotiable. Use only the core logo symbol or emblem — the single most iconic and reduced visual form of the brand. If [BRAND NAME] is primarily known by a symbol or icon (Nike Swoosh, Apple apple, Adidas trefoil, Mercedes star) — use that symbol only, no wordmark. If [BRAND NAME] has no standalone symbol and is only a wordmark — use the wordmark letterforms exactly as trademarked. Do not add taglines, descriptors, secondary text, or any accompanying copy that is not physically part of the core logo mark itself. The rhinestone crystal treatment is applied ON TOP of the correct logo geometry — transformation happens after accurate reconstruction, never instead of it. Fidelity test: a brand designer must recognize this as the correct primary mark, not an approximation. PHASE 1: LETTERFORM CONSTRUCTION Each letter and symbol of the [BRAND NAME] logotype is a fully three-dimensional physical block — thick, volumetric, depth of 20 to 30mm. The letterforms are the correct canonical shapes from PHASE 0 extruded into physical volume. Front face: flat — this is where the crystal surface lives. Side faces: visible at the slight camera angle, also covered in crystals. Edge treatment: a continuous polished chrome/silver metal border frames every letterform — precision-machined metal channel, 3 to 5mm wide, mirror-polished silver, IOR 2.5, roughness 0.008. Border outer edge: sharp chamfer catching light as a thin bright line against black background. Chrome border visible on side faces — silver band running the full depth of each letter. Letter spacing: tight but each chrome border individually visible. PHASE 2: CRYSTAL SURFACE SYSTEM — CRITICAL The entire front and all visible side faces of every letterform are completely covered in individual rhinestone crystals — zero gap, zero exposed base material. Crystal type: precision-cut faceted rhinestones — each crystal is a flat-back stone with a domed top consisting of exactly 8 to 16 individual planar facet faces. Each facet is a discrete flat mirror surface, roughness 0.0 — perfectly polished. Real gemstone binary behavior: each facet either reflects the light source directly as a sharp hot point, or reflects the dark environment as near-black. No medium uniform specularity. IOR: 2.0 to 2.4 — cubic zirconia range. The interior of each crystal shows genuine optical depth — multiple internal reflections visible inside each stone. Diameter: 3 to 5mm — larger and rounder than precision-cut stones, giving a more organic tactile quality. Packed in tight offset grid. Every crystal is an individual geometric object — real dome geometry, not texture map. Each crystal has: a smooth convex dome surface with a broad soft specular highlight at its highest point, a slightly darker zone around the base where it meets adjacent crystals, internal color depth — the crystal color is deepest at the base, lighter toward the top highlight. Crystal color system: autonomously determine the most iconic color or colors of [BRAND NAME]. If single dominant color — all crystals in that family with tonal variation. If multiple brand colors — distribute across different letters each carrying its own color family exactly as in the official brand palette. Color variation within each zone: 65% pure brand color, 25% slightly lighter, 10% slightly darker. Sparkle events: 6 to 12 bright multi-pointed star flares distributed across the composition at points of maximum light concentration. PHASE 3: LIGHTING Primary light: large softbox positioned upper-front at 30 to 40° elevation, 5500K neutral white. Softbox rather than hard spot — the rounded cabochon crystals respond better to slightly diffused light, producing broad smooth highlights rather than sharp binary facet reflections. Produces: thousands of soft rounded highlights across the crystal field, 6 to 12 multi-pointed star sparkle flares at maximum intensity points, bright specular lines along chrome border chamfers. Secondary fill: 10 to 12% from below — lifts shadow zones of lower crystal surfaces, maintains jewel richness throughout. No colored lights. PHASE 4: COMPOSITION & CAMERA — STRICTLY ENFORCED Background: absolute black #000000 — complete void, no gradient, no texture. Aspect ratio: 1:1 square. OBJECT SIZE — STRICTLY ENFORCED: logo occupies exactly 70 to 75% of total frame width, centered. Black void of 12 to 15% visible on each side — left, right, top, bottom. The logo is large, commanding, and fills most of the frame. CAMERA — STRICTLY ENFORCED: upward elevation 0 to 3° only — nearly perfectly frontal, barely any upward angle. Camera roll: 1 to 2° clockwise only. Zero Y-axis rotation — logo does not turn left or right. Zero X-axis tilt — logo does not lean forward or backward. The logo silhouette reads as the correct brand mark. Depth of field: none — full sharp focus. PHASE 5: TECH SPECS Render: Octane Render or Redshift — photorealistic jewelry photography standard. Crystal material: dielectric gem shader, IOR 1.6 to 1.9 — slightly lower than cut stones, appropriate for rounded cabochon style. Roughness: 0.02 to 0.05 — very slight softness on dome surface consistent with polished cabochon. Internal color: volumetric color depth within each crystal dome. Chrome: IOR 2.5, roughness 0.008 — mirror sharp. Ray tracing: minimum 16 bounces. Sampling: minimum 4096 samples per pixel. Anti-aliasing: maximum. No film grain. No post-process. Output feel: photograph of a real custom rhinestone-encrusted jewelry piece shot on black velvet by a professional jewelry photographer. FINAL CHECK — MANDATORY: logo width is 70 to 75% of frame. Camera roll is 1 to 2° only. Black void visible on all four sides. Logo is the correct canonical [BRAND NAME] mark. These rules override everything else.
