Butterfly Blue
Origin: China
Material: Natural granite (dense, exterior grade)
Butterfly Blue is a premium dark blue granite with a cool steel-blue base and a sparkling crystalline grain that can read as scattered silvery-blue highlights across the surface. It works as a strong “blue program” option for memorials—distinct from standard black/grey palettes while staying formal and architectural.
Visual Character (Color & Pattern)
Tone: Dark blue-grey / steel-blue
Pattern activity: Medium; granular “sparkle” with clouded shading (not veiny)
Texture: Fine to medium grain; visually stable on larger faces
Finishing Behavior
Polished / Gloss: Maximum depth and premium sheen; strongest “sparkle” effect for showroom faces
Honed / Matte (if specified): Reduced glare; calmer, more architectural dark blue
Engraving & Readability
Recommended: Polished inscription fields for crisp lettering and portraits
Because of the sparkling grain, layout planning is recommended for large portrait/text zones (select cleaner areas)
Recommended Applications (Memorial / B2B)
Uprights, slants, ledgers, bases, multi-piece sets
Premium models where a dark, formal blue tone is required
Why It Works for Partners (B2B)
Catalog differentiation: recognizable dark-blue segment beyond black/grey
Showroom value: polished surface sells visually and photographs well
Repeatable production: controlled pattern when ordered with lot/block control
Technical Data (from supplier card)
Mohs hardness: 6–7
Density: 2790 kg/m³ (≈ 2.79 g/cm³)

Quality & Matching Notes
Natural variation: intensity of blue tone and sparkle density can vary by lot
