Tucked along Peradeniya Road in Kandy, the Tiesh Gem Museum and Showroom offers one of the most comprehensive introductions to Sri Lanka's celebrated gem industry. Part retail destination, part educational experience, the 10,000-square-foot facility draws both first-time visitors and seasoned connoisseurs who want to understand where the island's sapphires, rubies, and cat's eye stones actually come from — before choosing one to take home.
What is the story behind Tiesh?
Tiesh traces its roots to 5 September 1997, when founder Lasantha De Fonseka opened Lakmini Pvt Ltd on a plot along Peradeniya Road that once formed part of the historic Panabokke Walauwwa estate. Starting with limited capital and no large corporate backing, De Fonseka built the business on what he describes as a "never-ending zest for excellence" — a philosophy that runs through every stage of production, from rough stone selection to the final setting.
The business is a family affair. Lasantha is joined by family members Bryony, Thiyasha, and Ayesh De Fonseka, and together they have steered Tiesh through more than two decades of growth. Today the showroom serves buyers from across Europe, North America, Australia, Japan, China, Russia, and Thailand, and it has established itself as a go-to supplier for discerning international travellers passing through the Kandy region.
What can you see and do at the Tiesh Showroom?
The showroom is divided into several distinct zones, making a visit feel more like a cultural tour than a conventional shopping trip.
- Geological Museum — Displays a curated collection of rough and polished gemstones alongside educational panels explaining how Sri Lanka's unique geology produces such a concentrated range of precious stones.
- Replica Gem Mine — A faithful recreation of a traditional pit mine of the kind found around Kandy and the gem fields further south. Visitors can observe the timber-lined shaft, the gravel-washing baskets, and the hand tools that miners use in the field — a rare chance to visualise the process without travelling to an active mining site.
- Testing Laboratory — Staffed by trained gemmologists, the lab uses standard industry equipment to assess clarity, cut, colour, and authenticity. Stones purchased at Tiesh are certified here before leaving the premises.
- Jewellery Workshop — An open workshop where craftspeople set stones into gold and sterling silver mounts. Watching the handwork gives context to the price differentials between mass-produced and bespoke pieces.
- Auditorium — Used for short orientation presentations that walk groups through Sri Lanka's gem-mining heritage, the grading system, and what to look for when buying coloured stones.
What gemstones does Tiesh specialise in?
Sri Lanka is one of the world's foremost sources of coloured gemstones, and Tiesh's collection reflects that breadth. The showroom carries:
- Blue sapphires and star sapphires
- Rubies and star rubies
- White sapphires and yellow sapphires
- Cat's eye (chrysoberyl)
- White diamonds and coloured diamonds
- A range of semi-precious stones including garnets, moonstones, and spinels
All stones are hand-selected, and the jewellery is crafted in-house rather than outsourced. Settings range from everyday wearable designs to elaborate pieces intended for special occasions, and prices reflect the breadth of that range.
Why visit a gem museum rather than just buying online?
Coloured gemstones are notoriously difficult to assess from photographs. Tone, saturation, and the presence of inclusions shift considerably under different light sources, and the phenomenon that gives star sapphires and star rubies their distinctive asterism is essentially invisible in a flat image. Visiting a showroom with a certified testing laboratory allows buyers to examine stones under controlled conditions, ask qualified gemmologists specific questions, and leave with documentation they can present to independent appraisers back home.
The replica mine and geological museum add a layer of context that changes how most visitors perceive the finished jewellery. Understanding that a single blue sapphire may require tonnes of riverbed gravel to be sifted by hand before it is recovered tends to recalibrate expectations around quality and value.
How do I get to the Tiesh Gem Museum from central Kandy?
The showroom sits on Peradeniya Road, the main artery connecting Kandy city centre with the Royal Botanic Gardens at Peradeniya. From Kandy's central bus stand or the railway station the journey takes around ten to fifteen minutes by tuk-tuk or taxi. Most tour itineraries that include a Kandy city tour can be extended to incorporate a visit without significant detour.
Is Tiesh suitable for group and tour-operator visits?
The facility was designed with group visitors in mind. The auditorium seats a sizeable audience for introductory presentations, and the showroom floor is spacious enough to accommodate coach parties without crowding. Tiesh has worked with international tour operators for much of its two-decade history and is experienced at pacing visits to suit different group sizes and time constraints. Pre-arranged group visits typically include a short guided walkthrough of the museum zones before free time in the retail area.
What should I know before buying gemstones in Sri Lanka?
Sri Lanka's gem trade is regulated, and reputable dealers issue certificates from recognised gemmological laboratories. When purchasing at Tiesh, ask to see the certification document for any stone above a certain carat weight, and check that it includes the species name, weight, dimensions, and any treatments applied. Heat treatment is common in the industry and is not inherently a problem, but it should be disclosed. Carry your receipt and certificate separately when travelling home, and be aware that import duties on jewellery vary by destination country — it is worth checking your home country's customs threshold before you buy.
