Origin-proven stone. No adulteration. Fresh daily rates and strict CFT measurement — the honest answer to a market full of fake Pakur.
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.

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.
A clean, traceable chain from the Rajmahal quarries to the Bangladesh border.
