For buyers new to the stone industry, understanding the complete journey of a granite carving — from quarry to port — helps in accurately gauging lead times and supply chain milestones.
Quarrying — Stone from different quarries varies in colour, grain, and veining. Decorative stone requires large, crack-free blocks with minimal colour variation. Extraction is done mainly by wire saw cutting; blasting has largely been phased out. It typically takes several days to free a sound raw block from the quarry face.
Block Transport and Warehousing — Raw blocks are trucked to the factory on flatbed trailers, each weighing several to over a dozen tonnes. At the factory, they are stockpiled by stone type, quarry source, and batch number. A factory's standing block inventory is a key indicator of its supply reliability.
Factory Processing — This is the most time-consuming stage. First, a suitable block is selected according to the order's dimensions and subject. The block is then rough-cut into a basic silhouette. Next comes the carving stage, divided into rough carving and fine detailing, followed by the surface finish. A standard planter takes about 7–15 days, a medium-sized stone lion 15–30 days, and a large custom fountain or complex relief may take 45–90 days or more.
Quality Inspection — A mature factory sets inspection checkpoints after rough cutting, after fine detailing, and before packing. The post-rough-cut check looks for hidden cracks; the post-detailing check verifies dimensions and details; a final visual inspection is done before packing. For custom orders, factories usually send photos or videos to the buyer at these two key stages for approval.
Packing — Standard products are secured on pallets with stretch wrap. High-value or irregularly shaped pieces require custom wooden crates with internal foam or timber bracing. Export wooden crates must comply with ISPM 15 standards and carry fumigation certification marks.
Container Loading and Customs Clearance — Large items are loaded by forklift, smaller ones by hand. Heavy items go in first at the bottom, and irregular pieces are braced with timber to fill voids. Customs clearance requires a packing list, commercial invoice, contract, and bill of lading. Some destination countries require a material test report or radiological certificate.
Time Reference — For a standard granite planter, the journey from block retrieval to container departure takes about 11–19 days. The processing period extends with product complexity. Quarry-side time is additional, though for common stone types factories usually keep standing inventory, so quarry cycles do not affect order lead times.
Differences in block selection standards, carving skill, and quality inspection rigour at each step ultimately show up in the product's price and its condition upon arrival.
