A Ratnapura day trip from Colombo

The Ratnapura day trip from Colombo combines a living industry, an important shrine and a landscape of paddy, rubber and tea under the hills of the Sabaragamuwa province. It suits travellers interested in gems, geology and local life, and it is a contrast to beach and fort trips.

Ratnapura sits in a wet, green valley close to the southern slopes of Adam's Peak. Gems are found in gravel layers called illam, washed down from the hills over millions of years.

The day runs from roughly 7 am to 7 pm, with roughly five to six hours of travel.

Visiting a gem pit near Ratnapura shows mining much as it has been done for centuries. Miners dig shallow pits supported by wooden frames, haul up gravel and wash it in woven baskets in a stream, looking for the glint of a stone.

Your driver or a reputable guide can arrange a visit to a working pit. Pits are on private land, so respect the workers, ask before photographing and offer a small tip if you have been shown around. Do not buy stones at the pit.

Gem mining is regulated in Sri Lanka, and pits are licensed. Many are seasonal, depending on water levels.

Gem scams are common around Ratnapura and across Sri Lanka. Strangers, friendly guides and even tuk-tuk drivers may steer you to shops or offer stones at a bargain to resell abroad. These are the most common scams; the stones are often synthetic, treated or worth far less.

Buy only from certified dealers, ask for an independent laboratory certificate, and check it with the National Gem and Jewellery Authority, which offers testing. Never pay for a stone you plan to resell, and never agree to carry stones for anyone.

If in doubt, buy nothing. A gem museum visit gives the knowledge without the risk.

The Maha Saman Devale is a major shrine to Saman, the guardian deity of Sri Pada, or Adam's Peak. The current complex dates largely from the Kandyan period, and a perahera procession is held around the shrine each year. Dress modestly and remove shoes.

In town, the gem market around the clock tower is busy on many mornings, with dealers trading parcels of rough stones. Watch from a distance; it is a professional market.

Ratnapura has several small gem museums, some attached to dealers, that display rough and cut stones with explanations of how gems form, how they are graded and how treatments change their value. Expect a sales pitch at the end, but a visit of roughly an hour gives you enough knowledge to spot an obviously poor deal elsewhere on the trip.

A private car and driver suits a Ratnapura day trip best, combining the pit, the shrine and the museum. Lankan Stays & Trails can arrange a driver who knows the area and a pit visit without commission shopping.

Ratnapura is in the wet zone, so carry an umbrella in any month. Combine the trip with Sinharaja on an overnight stay, or with tea estates on the road towards Balangoda.
