Import Black Granite — Buy in Bulk from Supplier in India

Silverstone Exporter supplies black granite from India in slab format, with source dimensions starting from 75 cm x 250 cm and a thickness of 20 mm. The material presents as a deep-toned natural stone with a polished surface finish, quarried and processed in Gujarat for export markets. This granite belongs to the igneous多少人 category known for dense crystalline structure and low porosity, properties that contribute to its resistance to staining and surface abrasion in installed applications.

The 20 mm thickness conforms to standard commercial slab specifications for interior vertical and horizontal surfacing, though residential countertop applications may require 30 mm lamination depending on span and load. Black granite from Indian quarries typically exhibits a Mohs hardness of 6-7 and water absorption below 0.5% by weight, though buyers should request specific test reports from Silverstone Exporter for the exact batch. The polished finish achieves a gloss meter reading typically between 80-95 GU at 60 degrees, standard for mirror-faced dimensional stone. Surface flatness tolerance for polished granite slabs typically runs to +/- 1.0 mm over a 600 mm straightedge, a parameter to verify during pre-shipment inspection.

Applications span kitchen countertops, bathroom vanities, flooring, wall cladding, and exterior landscaping elements in both residential and commercial construction. The supplier indicates availability of FOB and CIF shipping terms, with packaging described as secure for transit. Buyers should note the response rate stands at 0.00 with zero average response hours recorded, so direct outreach through multiple channels is advisable. MOQ flexibility is mentioned but not quantified, requiring confirmation. The supplier address in Surat, Gujarat places this material within one of India's major stone processing and export corridors.

Silverstone Exporter operates from 22, Gandhivihar Society, L.H. Road, Varachha, Surat 395006, Gujarat, India, positioning the company within one of India's principal stone processing and export hubs. The supplier tier is marked as imported with a harbor trust designation, indicating the profile originates from external data ingestion rather than direct platform verification. No response rate or average response time data is available, both fields showing zero, which limits assessment of communication reliability. The listing does not state year of establishment, production capacity, number of employees, or specific quarry ownership relationships.

The source description emphasizes polished black granite slabs with flexible MOQ, though no minimum quantity, price band, or sample policy is specified. Certifications mentioned include ISO compliance, though no certificate numbers, accreditation bodies, or valid dates are provided. Buyers should independently verify all quality claims and request material test reports, quarry origin documentation, and processing facility audits before committing. The Surat location suggests proximity to Gujarat's stone processing belt, but this does not confirm in-house fabrication versus trading operations.
