In the world of high-end luxury interiors and premium architectural design, black marble represents ultimate elegance.
Spider Black Marble, characterized by its deep charcoal-black background and intricate web of gold and orange veins, is a masterpiece.
Quarried in the Yazd and Dehbid regions of Iran, this natural stone is highly sought after for its dramatic visual contrast.
The unique spiderweb pattern, geologically formed by mineral deposits, flows beautifully across a dark recrystallized limestone base.
This high-contrast appearance, combined with the dense crystalline structure of marble, makes it a premier choice for feature elements.
When polished to a mirror-like high-gloss finish, the gold and orange veins appear to glow, giving the stone three-dimensional depth.
Its low water absorption and high compressive strength ensure that the marble retains its luxurious polish over time.
Geologically, Spider Black Marble was formed under high temperature and metamorphic pressure deep within the Earth's crust.
This recrystallization process closed the stone's pores, making it significantly harder than standard sedimentary limestones.
The golden and orange highlights are created by trace elements of iron oxide and copper minerals during geological cooling.
At SherkatStone, we coordinate closely with selected quarries to secure blocks with high concentrations of golden web veins.
Each slab is meticulously inspected for structural soundness and vein uniformity to guarantee premium export quality.
The value of Spider Black Marble is directly tied to the density, color, and distribution of its gold and orange veins.
During B2B selection and slab inspection, our quality control inspectors evaluate several parameters:
Vein Density: Uniform distribution of gold and orange spiderweb patterns across the entire face of the slab.
Color Intensity: The strength and definition of the gold and orange reflections under artificial lighting.
Background Consistency: A deep, uniform black background free of white calcium spots or dull grey patches.
Structural Soundness: Verification that the large crystalline veins are stable and free of micro-cracks.
Due to its striking contrast and high polish, Spider Black Marble is highly versatile for luxury interior applications:
Key applications in B2B projects include:
Premium Lobby Flooring: Perfect for high-traffic entrance halls in commercial buildings and luxury hotels.
Bookmatched Feature Walls: Bookaligned slabs that serve as stunning natural focal points in lobbies.
Luxury Vanity Tops: Highly resistant to water and daily wear, adding a luxurious touch to bathrooms.
Fireplace Surrounds: Heat-resistant properties and dramatic veining make it perfect for fireplaces.
Architects frequently specify Spider Black Marble for projects that require a strong statement of luxury.
The black and gold surface contrasts beautifully with modern materials like brushed brass, concrete, and light wood.
Furthermore, the low porosity of the stone ensures that it resists staining when properly sealed and maintained.
At SherkatStone, we operate as a dedicated trade and quality assurance coordinator for international buyers.
We source raw Spider Black blocks directly from Yazd/Dehbid quarries and coordinate processing with advanced factories.
This model allows us to manage quality at every step, ensuring that only calibrated and well-polished slabs are exported.
Our inspectors visit the processing yards to verify the quality of diamond-wire sawing, resin reinforcement, and polishing.
Each slab is measured for thickness consistency to ensure simple, error-free installation on site.
We group our products into distinct grades based on vein density (Super, Premium, Standard) to fit project budgets.
Our trade coordination model provides clients with complete transparency, regular progress photos, and direct communication.
We handle all export documentations, helping to streamline customs clearance in the destination country.
Our Spider Black Marble is tested against international standards to ensure engineering compliance:
| Physical Property | Testing Method | Measured Value |
|---|---|---|
| Bulk Specific Gravity (Density) | ASTM C97 | 2.73 g/cm³ |
| Water Absorption | ASTM C97 | 0.18% |
| Compressive Strength (Dry) | ASTM C170 | 110 MPa |
| Compressive Strength (Wet) | ASTM C170 | 95 MPa |
| Modulus of Rupture | ASTM C99 | 10.8 MPa |
| Abrasion Resistance | ASTM C241 | 20.0 Ha |
We supply Spider Black Marble in various commercial formats to meet specific design requirements:
Gang-Saw Slabs: Available in 20mm and 30mm thicknesses, with dimensions reaching 2800mm x 1600mm.
Calibrated Tiles: Standard tiles including 300x600mm, 600x600mm, and 800x800mm formats.
Custom Staircases: Cut-to-size treads and risers with polished, bevelled edge profiles.
Raw Blocks: Export-grade blocks ranging from 15 to 25 tons, inspected for internal flaws.
Our processing lines utilize modern gang-saws to ensure precise cutting and minimal waste.
Spider Black's mineral structure can be finished in several ways to achieve different visual effects:
Polished: High-gloss finish that maximizes reflections, highlighting the gold and orange veins.
Honed: A smooth matte finish that offers slip-resistance while retaining subtle vein reflections.
Brushed: A textured matte finish that provides a vintage, antique appearance.
For polished slabs, we use advanced multi-head polishing lines to achieve a mirror-like shine.
As a premium marble, Spider Black requires proper care to maintain its high-gloss reflection:
Initial Sealing: We recommend applying a high-quality impregnating sealer after installation.
Daily Cleaning: Wipe with a damp cloth and mild pH-neutral stone cleaner. Avoid acidic cleaners.
Stain Prevention: Wipe up spills promptly, especially acidic liquids like lemon juice or vinegar.
Safe transit requires secure packaging designed for international heavy cargo shipping:
Wooden A-Frames: Large slabs are secured on heavy-duty, fumigated wooden A-frames.
Strong Wooden Crates: Tiles are packed in reinforced, foam-lined wooden crates.
Strapping & Bracing: Steel bands and timber braces are used inside the container to prevent shifting during transit.
We coordinate global logistics through reliable sea and land transport networks:
Sea-Freight: Shipments are dispatched from Shahid Rajaee Port (Bandar Abbas) to major global ports.
Land-Transit: Direct truck transit via Astara to Russia/CIS and Bazargan to Turkey/Europe.
Customs Documentation: We provide full export documents, including Certificate of Origin and SGS inspection reports.
