Quarry-direct boulder, chips and aggregate for EPC, RMC and infrastructure buyers. Share your delivery PIN and tonnage for a commercially screened quote backed by source records and lot-specific documentation for buyer-agreed parameters.
Pakur stone is heavy and price-sensitive. We qualify the lane before quoting so you receive a usable delivered price—not an ex-quarry number that collapses after transport.
Truck and tipper supply is usually the first mode assessed.
Recurring volume, vehicle utilization and payment terms decide viability.
Best for rake-scale demand with a workable unloading point and short last mile.

Pakur basalt comes from the Rajmahal trap formation. We pair the material with a named quarry source, legally shareable mining and dispatch references, and lot-specific test documentation for parameters agreed with the buyer.
Vajrashila Global exists to remove procurement guesswork: source records, a declared MT or CFT measurement protocol, freight shown separately, and documentation matched to the supplied lot.
The real procurement risk is not the sample—it is whether the dispatched lot, source documents, measurement and delivered economics match the quotation.
Vajrashila Global supplies quarry-direct Pakur black basalt from the Rajmahal trap belt: uncrushed boulder, graded chips and crusher dust for commercial buyers. The quoted source, grade, billing unit and dispatch documentation are stated before order confirmation.
For agreed orders, we provide applicable lot-specific test documentation, identify the tested parameters against the buyer's specification, and support MT weighment or a declared CFT protocol. Delivered pricing is issued only after the destination and freight lane are reviewed.
Crushed and graded to order. Standard chip sizes below; boulders and custom gradations available on request.
Dense, fresh-fractured black basalt boulders for crushing units and heavy fill.
Primary coarse aggregate for RCC, ready-mix and structural concrete.
Versatile gradation for concrete, road base and precast work.
For thinner sections, plastering aggregate and dense concrete mixes.
Fine aggregate for flooring, tile work and dense mix designs.
Quarry dust and graded sub-base material for filling and compaction.
Indicative properties for initial evaluation. Final acceptance should use the buyer's specification, representative sampling and the report matched to the supplied lot.

Values are indicative, not a universal product guarantee. Request the applicable lot report, sampling basis and laboratory scope before technical acceptance.
Visual and field checks can screen obvious mismatches, but they do not prove geographic origin or lot compliance. Use them with source records, representative sampling and the applicable laboratory report.
A laboratory report proves the tested sample's results—not geographic origin by itself. Verify the report number, tested parameters and sampling basis, then match them with the named source, legal dispatch records, vehicle or rake and buyer receipt.
A documented chain from the named Pakur source to a freight-approved project, plant or stockyard.
Share grade, tonnage, destination PIN and timing; we separate material, freight and trade terms.
Agree terms, MOQ and delivery details; order confirmed with an advance payment.
Prepare the agreed grade, attach applicable lot documentation and record the declared measurement.
Dispatch by the approved mode with GST and transport documents, then reconcile destination receipt.
Choose the nearest market brief, then submit the exact destination PIN and tonnage. Every page states the likely mode, commercial order category and documentation available without inventing a fixed freight price.
Search the complete preliminary geographic screen, then qualify freight using the exact delivery PIN and tonnage.

Colour, grain, density, water and ring checks are useful screening tools, not final proof. Technical acceptance should use representative sampling and applicable test results; origin should be matched through named-source and dispatch records.
Standard gradations are 20mm (3/4"), 16mm (5/8"), 12mm (1/2") and 6mm (1/4") chips, plus uncrushed boulder and stone dust / down. Custom gradations are crushed to order.
Lot-specific test reports may be provided for agreed parameters. Review the report number, sampling basis and test date; acceptance depends on the buyer-approved specification and sampling plan.
MT orders use weighment documentation. CFT orders use an agreed vehicle-body and levelling method. The quote states the billing unit, tolerance, GST, loading basis, freight and payment terms.
Road is prioritized within roughly 300 km of Pakur and reviewed selectively up to about 500 km. Longer distances require a rail or named-account review based on tonnage, siding, unloading and last-mile economics. Submit the destination PIN for a decision.
Minimum order quantity depends on grade and delivery distance — share your requirement on WhatsApp for a clear MOQ. Payment is by advance or on delivery, with a GST invoice issued for every order.
