Gunasekara Constructions Ltd supplies Pure Natural Quartz Lumps that consist of natural quartz (SiO₂) mined in the Rathnapura region of Sri Lanka. The lumps are washed, inspected and packed for export directly from the Colombo port. Each piece contains a high silica content that meets typical industry expectations for purity above 99 %. The material is delivered in 20 ft containers as requested by the buyer.
In the mineral market, quartz lumps of this grade are characterised by low moisture levels, usually below 0.5 % by weight. Bulk density commonly falls between 2.6 and 2.7 t/m³, which influences transport calculations. Particle size normally ranges from 10 mm to 50 mm, a size that suits melting processes in glass and ceramic production. The product conforms to standard testing methods such as ASTM D388 for silica content verification.
Primary users include glass manufacturers, ceramic producers, foundries and other industrial processors that require consistent silica feedstock. Buyers can arrange monthly shipments, with the supplier able to load full‑size containers on short notice. Payment is typically made by irrevocable Letter of Credit or direct bank transfer as stipulated in the sales contract. The supplier’s harbour‑tier verification signals that the company has passed basic compliance checks on the marketplace.

Before placing an order, importers should request a recent assay report confirming silica purity and a moisture analysis to ensure the material meets their process limits. Verify that the quartz originates from the Rathnapura mines and that the supplier can provide documentation of the mining and washing procedures.
Logistics should be coordinated around the Colombo shipping port. Buyers need to confirm the Incoterm (typically FOB Colombo) and agree on container size, whether the standard 20 ft or an alternative, as well as the expected lead time for the monthly supply schedule. Payment by LC or bank transfer should be reflected in the sales contract.
Quality assurance is best managed through a third‑party inspection agency. Request an SGS or equivalent inspection report covering particle size distribution, bulk density and moisture content. Ensure that the supplier can provide the relevant test certificates before the cargo is loaded for export.
