Kandy is the principal city of the central highlands of Sri Lanka, capital of the last independent Sinhalese kingdom before British annexation in 1815, and a UNESCO World Heritage Site for its cultural and religious significance — most prominently as the home of the Temple of the Sacred Tooth Relic (Sri Dalada Maligawa). In gem-trade terms, Kandy occupies a secondary but real position within the Sri Lankan industry: it is not a primary mining district in the way Ratnapura or Elahera are, but it functions as a regional cutting and trading centre, a tourist-facing retail hub, and the access point to the secondary deposits of the surrounding Kandy district and the corundum-bearing belt that extends north-east toward Matale.

The Kandy district deposits

The geology of the central highlands is part of the Highland Complex of Sri Lanka, the Precambrian metamorphic basement that hosts the country's principal corundum, spinel, garnet, tourmaline and beryl mineralisation. The Kandy district itself produces sapphires, garnets, quartz and feldspar from the alluvial gravels of the Mahaweli river system, with notable workings around Kalugala, Pussellawa and Galaha. Production is small-scale and modest in volume relative to the major fields at Ratnapura (south-western alluvium) and Elahera (north-central marble-related deposits), and Kandy material is generally absorbed into the broader Sri Lankan supply rather than tracked separately.

Kandy as a trade and cutting centre

Kandy hosts a working gem-cutting community, several established lapidary workshops, and a tourist-oriented retail trade that has expanded steadily since the end of the civil conflict in 2009. The principal industry-grade trading still happens at Beruwala on the south-west coast and in Colombo, with Ratnapura functioning as the dealer market closest to the mines, but Kandy is a recognised secondary node and a significant point of sale for the international visitor market. The National Gem and Jewellery Authority (NGJA) of Sri Lanka licenses dealers in Kandy, and the city's gemmological community participates in the broader infrastructure of training, valuation and certification administered through the NGJA's Colombo headquarters.

Corundum and the Kandy retail market

The product mix in Kandy retail leans toward Ceylon blue, yellow, pink and padparadscha sapphires, blue and white moonstone, alexandrite and cat's-eye chrysoberyl from Sri Lankan sources, garnet, spinel and topaz. Heat-treatment is the dominant treatment and is locally performed; beryllium diffusion is not a standard practice in the legitimate Sri Lankan industry and disclosure norms align with the international AGTA and CIBJO frameworks. Kandy's retail trade has the same trust dynamics as the rest of the Sri Lankan visitor-facing market: legitimate operators with NGJA licences and laboratory documentation coexist with a tourist-bait fringe that warrants caution.

Cultural significance

The historic significance of Kandy to Sri Lankan jewellery is bound up with the regalia of the Kandyan kingdom and the temple treasures of the Sri Dalada Maligawa. The royal jewellery housed in collections such as the National Museum of Kandy and pieces still associated with the Esala Perahera processions represent some of the most important surviving examples of Sinhalese court jewellery, and the techniques preserved in those works — high-karat granulation, repoussé in 22-karat gold, traditional gem-set pendants — continue to influence the contemporary Sri Lankan craft tradition.

Trade significance

For the international gem buyer, Kandy is best understood as a recognised but secondary destination within the Sri Lankan sourcing network. The principal wholesale activity remains at Ratnapura and Beruwala, but Kandy is a legitimate cutting and dealing centre with its own licensed trade and a useful access point to the central-highlands material. Stones with documented Kandy-district provenance are not separately graded by the major laboratories beyond the broader Sri Lankan origin attribution.
