Import 3.47 Ct Natural Green Zircon — Buy in wholesale FOB from Supplier in Sri Lanka

This 3.47 carat natural green zircon from Sihala Gem Zone is a single-stone offering mined in Sri Lanka, a source region prized for zircon's exceptional dispersion and clarity potential. The gem measures 8.55 mm by 7.20 mm by 5.42 mm in a cushion mixed cut, a shape that preserves weight while allowing light return through the large table and scintillating facets. The VVS clarity grade indicates minute inclusions difficult to locate under 10x magnification, a quality level that supports setting in fine jewellery without optical distraction. No treatment is declared, which for green zircon typically means the colour is natural and not the result of heat or irradiation enhancement.

Zircon is a nesosilicate mineral with the formula ZrSiO₄, occurring in metamorphic and igneous rocks across Sri Lanka's alluvial deposits. The green hue in this specimen arises from trace uranium and thorium content, which also accounts for the material's characteristic radioactivity (measured in microcuries per gram, typically negligible for jewellery use). The refractive index of zircon ranges from 1.777 to 1.987 depending on crystal axis, giving it higher brilliance than most coloured gemstones except diamond. Hardness on the Mohs scale is 6 to 7.5, with the direction parallel to the c-axis typically softer, a factor that influences cutting orientation and setting precautions. Specific gravity for zircon is 4.2 to 4.8, noticeably heavier than sapphire or spinel, a useful diagnostic for separation from simulants.

This stone suits collectors and jewellery manufacturers seeking an uncommon green hue in a durable, brilliant gem. The cushion mixed cut with its rounded corners and large facets works well in rings and pendants where light entry is maximised. Sri Lankan zircon commands premium recognition in the trade for its transparency and colour purity. Buyers should confirm with Sihala Gem Zone whether a gemmological report from an accredited laboratory accompanies the stone, what the return conditions are for overseas purchases, and whether customs documentation for CITES or export permits from the Sri Lanka Gem and Jewellery Authority is provided.

Sihala Gem Zone is located at 193/c/1, Ihalagama, Gampaha, Western Province, Sri Lanka 110000, a district within the traditional gem-producing region north of Colombo. The supplier operates under a 'harbor' trust tier with a 0.00% response rate and 0 hours average response time recorded on the platform, which suggests that direct communication channels may be necessary to secure a reply. The business appears to be a small-scale or individual dealer rather than a large export house, given the single-stone listings and residential-style address format.

No information is provided about year of establishment, company registration, membership in the Sri Lanka Gem and Jewellery Association, export volumes, or banking references. The listing indicates free registered air mail as standard shipping, with EMS express at additional cost. Buyers should verify the supplier's business registration, request copies of export licences from the National Gem and Jewellery Authority, and confirm whether the supplier can provide a formal invoice acceptable for customs declaration. No client references, physical showroom details, or participation in international trade shows are mentioned in the available data.
