Product Range and Specialties of Gunasekara Constructions Ltd

The supplier’s catalogue covers three gemstone groups - cut and polished gemstones, Sri Lankan blue sapphire and natural alexandrite - each commonly graded by carat weight, colour grading, clarity and origin certification. In the precious‑stone market, buyers frequently request a gemological report conforming to GIA or IGI standards. The silver jewellery entry is likely to be made of sterling silver (925 % Ag) and may carry hallmarks indicating purity and manufacturer. Essential oils such as the listed aromatherapy oil are usually sold as therapeutic‑grade products with a purity of 98 % or higher, verified by GC‑MS analysis. Natural quartz lumps (HS 2506.10) typically contain SiO2 purity above 99 % and are supplied in bulk bags or wooden crates for industrial use. Hand‑made batik garments and sarees are traditionally woven from cotton or silk, with GSM values ranging from 120 to 250 depending on the fabric weight. Buyers of these textile items often look for Oeko‑Tex or ISO 9001 compliance to assure safe dyeing processes.

Trade and Export Information - Gunasekara Constructions Ltd

United Kingdom exporters of gemstones and mineral products generally target markets in the Middle East, South‑Asia and the United States, where demand for coloured stones and quartz for electronics is strong. HS chapter 71 covers precious and semi‑precious stones, while chapter 71.13 is used for jewellery, and chapter 33.01 for essential oils. Importers typically require Kimberley Process certification for coloured stones, REACH compliance for essential oils, and ISO 9001 quality management for jewellery and textile shipments. Logistically, quartz lumps under HS 2506.10 are shipped in 20‑ft or 40‑ft containers on wooden pallets, often on FOB or CIF terms. Gemstones and jewellery are packed in reinforced wooden boxes with individual compartments to prevent abrasion. Batik garments and sarees are usually folded and placed in sealed cartons, sometimes with moisture‑absorbing packets to preserve fabric quality. Export documentation from the United Kingdom commonly includes a commercial invoice, packing list, certificate of origin, and where applicable, a Kimberley Process certificate for sapphires and other coloured stones.

Sourcing from Gunasekara Constructions Ltd - Buyer Guidance

When sourcing gemstones from Gunasekara Constructions Ltd, request a gemological report that details carat weight, colour grade, clarity and any treatment history. Verify that the supplier can provide Kimberley Process documentation for blue sapphire and any other coloured stones to confirm conflict‑free origin. For the aromatherapy oil, ask for a recent GC‑MS test report, a Certificate of Analysis showing purity (≥98 %) and compliance with REACH regulations. The quartz lumps should be accompanied by a material safety data sheet (MSDS) and a purity assay confirming SiO2 content above 99 %. Silver jewellery buyers should request a hallmark verification or a mill‑test report confirming 925 % silver content. For batik garments and sarees, ask for fabric composition details, GSM, and any Oeko‑Tex or ISO 9001 certificates that attest to safe dyeing and production practices.
