Origin-proven, NABL lab-certified Pakur black basalt — boulder, chips and aggregate. No adulteration. Fresh daily rates and strict CFT measurement — the honest answer to a market full of fake Pakur stone.
Fresh quarry-direct pricing, updated daily. Final price is confirmed per consignment on WhatsApp.
Pakur basalt is among the densest, blackest aggregate stone mined in India — drawn from the Rajmahal trap formation. We supply it the way it should be supplied: from a named quarry, with a mining-lease reference, and a NABL petrographic certificate behind every consignment.
Vajrashila Global exists to end the guesswork. Genuine origin, transparent daily pricing, strict cubic-feet measurement — so the stone that lands at your site is exactly the stone you paid for.
Choosing a stone exporter in India too often means trusting a name and hoping the loaded truck matches the sample. We were built to remove that risk.
Vajrashila Global is a Pakur black stone exporter working quarry-direct from the Rajmahal trap belt in Pakur, Jharkhand. We supply genuine black basalt — uncrushed boulder, graded stone chips and crusher dust — with documented origin behind every single consignment, not traded through layers of middlemen.
As a black stone exporter in India serving importers across Bangladesh, we measure on strict cubic feet (CFT), grade to IS 383, and back each load with a NABL petrographic test report tied to a named mining-lease. No adulteration, no short-loading — and a fresh daily rate shared on WhatsApp before you ever commit. That is what separates a stone supplier from a stone exporter you can actually trust.

Values are indicative of genuine Pakur basalt. Exact figures are confirmed per consignment on the issued NABL test report.
“Pakur” is a name many sellers borrow and few can prove. Use these six checks to tell genuine Rajmahal basalt from cheaper, weathered or mixed stone — before you pay.
The visual checks weed out the obvious fakes — but the only proof that survives a dispute is a lab report. Every Vajrashila Global consignment ships with a NABL test certificate and petrographic confirmation tied to our named quarry and mining-lease. Ask for it before you place a trial order.

The questions importers ask most before placing a first order with a Pakur stone exporter.
Genuine Pakur black stone is a deep, uniform black to charcoal grey with a fine, dense crystalline grain and a clean fresh fracture. It is noticeably heavy (specific gravity around 2.85+), absorbs almost no water, and gives a clear sharp ring when struck. Imitations show brown, reddish or patchy colour, feel light, absorb water, sound dull, and lack a NABL report tied to a named quarry.
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.
Yes. Every consignment carries a NABL lab report with petrographic confirmation of basalt, tied to a named quarry source and mining-lease reference, and is graded to IS 383.
Material is billed on strict, true cubic-feet (CFT) measurement with no short-loading, on LC trade terms with a clear minimum order quantity and delivery boundary. A fresh daily rate is shared on WhatsApp before you commit.
