Martapura: Gem Town of Banjar Regency, Access and What to Expect
Martapura is the seat of Banjar Regency in South Kalimantan and the island’s best-known centre for gemstones, especially diamonds. Its streets hold jewellers, cutting workshops and polishing rooms, and the trade in stones shapes the town’s economy and its daily rhythm. Visitors who come for the gems will find a place that is more commercial than most regency towns in the province, while still keeping a calm riverside and village character at its edges.
The wider province is covered in the South Kalimantan guide, which sets out the towns, routes and coastal and river landscapes. Martapura is one of the stops that many travellers pair with the provincial capital.
Why Martapura Became a Gem Centre
Diamonds have been mined from the alluvial deposits of the Banjarmasin and Martapura area for a very long time. Gravel and sand carried down by rivers hold stones that were washed out of older rock, and local people learned to work those deposits by hand. The trade grew around the riverbanks and then around the town, so that the shops and workshops developed where the stones were found and sorted.
Martapura also has a political history. In the seventeenth century it served as a royal seat of the Banjar Sultanate, and the town’s importance as a centre of rule helped it grow into a place where goods and skills gathered. The gem trade came to be part of that older urban life.
Mining the River Deposits
Traditional mining in the area works through the river gravel. Small teams of workers, often groups of eight to ten people, pump gravel from the riverbed and then sift it through woven baskets shaped like a wide-brimmed hat. The sieving separates the heavier material, and the workers search the remainder for stones. The work is hard, depends on the season and the water level, and is often done by people who know the river well.
A notable find came in 1960, when a very large diamond of about 167 carats was recovered from the diamond fields of Cempaka district in the Banjar area. President Sukarno gave the stone the name Intan Trisakti, and it became one of the best-known Indonesian diamonds of its time. Finds of this kind are part of why the town’s gem trade is so closely watched, and why buyers from across the country come to look at what the workshops produce.
The Gem Trade and Its Workshops
The diamond industry is the town’s defining activity. Stones are sorted, cut and polished in workshops that range from small rooms at the back of family houses to larger shops at the front of the main streets. The finished pieces are sold in the town’s shops and sent to buyers across Indonesia. Jewellery made in Martapura includes pieces set with diamonds, gold, zircon and other gemstones.
Most workshops are small and home-based, and many of them still work with simple hand tools. Cutting a stone takes patience, because the cutter must choose an angle that brings out the light without losing too much of the weight. A visitor who asks to watch a cutter at work will learn quickly how much skill the trade depends on.
- Rough stones are sorted by size, colour and clarity before cutting.
- Cutting and polishing take place at small benches in workshops.
- Finished stones are set into rings, pendants and earrings in the shops.
Buying Gems Carefully
The gem market rewards patience. A buyer should ask to see stones under good light, should compare several pieces before deciding and should ask for a clear description of what is being sold. The value of a stone depends on its cut, clarity and colour, and quality varies widely even between stones that look similar at first glance. Haggling is normal in many shops, but it works best when the buyer already knows what a fair price looks like for the item.
Ask for a clear description of each stone, including its type and its weight, and keep it with the purchase. Compare the same kind of stone in several shops before you commit, and walk away if the seller will not let you examine the item closely.
Visiting the Workshops
Many workshops welcome visitors who come quietly and ask questions. Go in the morning, when the light is good and the workers are fresh, and ask before taking photographs inside any room. A guide who knows the town can explain the stages of cutting and setting and introduce you to a workshop that is used to visitors, which is a better way to see the work than walking in unannounced.
The Town and Its Surroundings
Beyond the gem trade, Martapura has a traditional market, schools, offices and a network of residential streets. Its position between the city and the countryside means that villages, gardens and rice fields are close to the town centre. Travellers who leave the main road will quickly find themselves among small houses and fields.
The region’s rivers and canals are part of its older landscape. Many of the earlier settlements grew along the water, and the canals still shape how people move around the district. The Martapura river runs through the area, and its banks show how the town was built around the water.
The city of Banjarmasin, with its many waterways, lies within easy reach. The Banjarmasin travel guide describes the river city and its markets, which make a useful second stop for anyone travelling between the two towns.
Getting There and Around
Martapura is reached by road from Banjarmasin,. The road from Banjarbaru is shorter, and the two towns are close enough to be part of one urban area. Local transport connects the town with the nearby cities, and motorbikes and shared vehicles are common. Traffic can be heavy in the mornings and evenings, so it is wise to plan trips outside the busiest hours.
Inside the town most places can be reached on foot or by a short local trip. Shops and workshops are concentrated in the central streets, and the market is busiest in the morning. Walking the main streets is the easiest way to see the range of shops and to get a sense of how the trade works day to day. The Banjarbaru travel guide covers the neighbouring city, which many visitors pass through on the way.
Planning a Visit
Carry cash for small purchases and for transport, since card payment is less common in smaller shops. Bring water, sun protection and a light rain layer, because the weather can change quickly. Expect limited English in the shops and learn a few Indonesian phrases, such as greetings and polite requests, which go a long way with sellers. A short greeting before any question sets a friendlier tone, and it makes it easier to ask a seller to slow down or show you a stone a second time. Dress modestly when visiting homes or workshops, and ask before taking photographs inside any shop.
Give yourself a full morning for the gem district and an afternoon for the rest of the town. Keep a little time spare at the end of the day, because the drive back to the larger city can be slow when the roads fill with traffic. Shops close at different times, so ask locally when a particular workshop is open before you set out.
Banjar Heritage and Local Life
Martapura sits within the Banjar cultural area of the south, where the Banjar language and customs are part of everyday life. Visitors who take the time to talk with shop owners often hear about how a family came to the trade, how the river has changed and how the workshops of one generation differ from the next. The peoples of Indonesia page explains the Banjar communities of the south and their place in the wider country.
Gems are the best-known craft here, but the trade sits alongside other everyday work, and many households combine a small workshop with farming, trading or running a shop. The Indonesian culture page covers the crafts and arts of the wider country, which helps place Martapura’s jewellery in a longer tradition of skilled handwork.

A good route is to arrive in the morning, spend the middle of the day in the workshops and the market, and return to the larger city before the evening traffic builds. Martapura rewards a slow visit, and a visitor who listens will learn more about the trade than from any single shop.
