From the Island of Gems
We are a Sri Lankan luxury gemstone house presenting rare gemstones through heritage, craftsmanship, knowledge, and trust.
The Jeweller for the Jewellers
Lankaratna is the export and trade house of Muthukaruppan Chettiar Jewellers - manufacturer, exporter, and renowned, trusted sourcer of exclusive Ceylon gemstones for jewellery houses and retailers worldwide.
For Business Partners
We are not a marketplace. We are the workshop itself - a family of goldsmiths and gemstone artisans in Colombo since 1937, manufacturing and exporting on behalf of jewellery houses, retailers, and brands who require a partner they can trust with their name. Every stone we source and every piece we craft carries the same discipline we would apply to our own collection.
Our studded jewellery is handmade, not machine-cut - set by hand, at the bench, wholeheartedly, by the same artisans who have practised this craft for generations.
A renowned, trusted sourcer of exclusive Ceylon gemstones - sapphires, rubies, and rare colour stones, supplied direct from mine to your workshop.

Master Craftsmanship
Lankaratna is the export-facing house of Muthukaruppan Chettiar Jewellers, a family name that has practised goldsmithing and gemstone craft in Colombo since 1937. Every piece that leaves our workshop carries that same discipline - learned at the bench, passed from one generation of artisans to the next.

Explore the Island of GemsA gemstone is never just an object of beauty. It is a convergence of geology, culture, and human experience. We exist to honour that convergence.
The House
Each gemstone we curate carries a journey shaped over millions of years, from mine to masterpiece - formed by nature, refined through Sri Lanka’s gem heritage, and completed through human craftsmanship. We do not simply present gemstones. We present meaning shaped by time.
Read Our StoryOur Signature Stone
Among the rarest sapphires in the world, Padparadscha is known for its delicate harmony of pink and orange - resembling the first light of dawn. Found primarily in Sri Lanka, it is a gemstone that reflects rarity not only in form, but in spirit.
Discover PadparadschaGemological Expertise
Hue, tone, saturation, clarity, pleochroism, crystal habit - the language of gemology is precise for a reason. Every stone we present has been examined against that standard, not simply described in passing.
