Category: Natural Granite Stone (Quarry Rough Raw Block)
Color: Profound solid jet‑black base tone interspersed with sparse tiny silvery‑grey mineral speckles; deep monochrome tone, concise texture and exclusive solemn noble artistic temperament
Surface Finish Available: Rough Quarry Face / Polished / Honed / Leathered / Flamed / Bush‑hammered
Block Form: Rough Quarry Raw Block
Texture: Compact fine‑grained granite crystalline texture with uniform interlocked mineral grains; achieves flawless high‑gloss mirror polishing to fully display deep pure black surface with faint mineral sparkles; leather and honed finishes present soft matte texture ideal for interior furniture tops; flamed finish provides anti‑slip performance for outdoor engineering
Density: 2.65 – 2.72 g/cm³ (High compactness; guarantees reliable structural stability and long‑lasting decorative durability for prolonged indoor & outdoor heavy‑duty application)
Water Absorption: < 0.19% (Low water permeability; perfectly applicable for interior flooring, wall cladding, countertops, dining tops, wet areas and exterior facade decoration projects)
Compressive Strength: 160 – 192 MPa (Excellent structural strength and pressure resistance; suitable for large‑scale engineering decoration and long‑term high‑frequency usage scenarios)
Abrasion Resistance: Great wear, scratch and stain resistance, vastly superior to ordinary marble; ideal for high‑traffic luxury floors, solid‑tone artistic feature walls, custom dining tops & countertops and bespoke stone decorative furnishings
GANGSAW SUITABILITY
Ykd Jet Black Granite raw quarry blocks are fully compatible with standard gangsaw processing equipment. Regular quarry block dimensions fit optimal gangsaw cutting ranges. The stone features homogeneous internal crystallization with stable overall hardness and sporadic minor natural mineral cleavage. Mineral speckle distribution varies slightly between individual blocks, bringing moderate controllable processing loss. It serves as a classic high‑end black‑toned rough granite raw block for mass slab production and modern luxury architectural projects.
Recommended Processing: Gangsaw slabs (1.8 cm & 2 cm), followed by calibration, edge trimming and high‑gloss mirror polishing / honed / leathered finish
Expected Slab Yield: Approximately 76‑86 slabs per block (based on 1.8 cm thickness)
Polish Result: Deep pure jet‑black high‑gloss mirror surface with subtle scattered silvery‑grey mineral speckles, presenting solemn concise layering, profound monochrome tone and exclusive modern minimalist luxury decorative appearance
About
Texture
Ultra-fine holocrystalline compact texture, tightly locked mineral grains, ultra-low void rate, sturdy rough block ideal for slab cutting and various surface finishing processes.
Pattern and Veining
Uniform pure jet black base with negligible faint mineral specks, almost zero messy veining, neat unified appearance after processing with minimal color difference.
Durability
Outstanding freeze-thaw resistance, extremely low water absorption, superior anti-weathering & anti-abrasion capacity, long service life for permanent exterior and high-traffic commercial projects.
Available Surfaces
Polished, Bush Hammered, Sandblasted
Acid Sensitivity
Excellent resistance to daily weak acid and acid rain erosion; prolonged contact with hydrofluoric acid & strong acidic cleaners will cause surface matte fading, which needs strict avoidance.
