Madagascar is renowned for its strange landscapes and wildlife, but underneath its soil is another kind of treasure. The island is an important source of coloured gemstones, especially sapphires. Among the places most closely associated with the trade is Ilakaka, a small settlement in southern Madagascar that became famous after major sapphire discoveries in the late 1990s.

Madagascar’s story of sapphire mining is more than just the discovery of valuable stones. It is also about geology, small-scale mining, sudden economic change, and the people who make a living from the ground beneath their feet. Today, Madagascar continues to produce sapphires. The U.S. Geological Survey estimates national sapphire production at about 2,100 kilograms per year from 2021 through 2024, although gemstone production figures are estimates because this type of mining is difficult to measure accurately.
Ilakaka and the Rise of Sapphire Mining
Before these discoveries, Ilakaka was a much quieter place. The arrival of miners, traders and gemstone buyers transformed the settlement and surrounding region. This is one reason the name Ilakaka sapphire is now familiar to people interested in coloured gemstones.
Why Is Madagascar Famous for Sapphires?
The country's gemstone industry is also unusually diverse. The USGS lists sapphires alongside other gemstones produced in Madagascar, including ruby, emerald, garnet, tourmaline, amethyst and labradorite. That makes Madagascar more than just a sapphire destination. It is one of the world's most interesting sources of coloured gemstones.

How Are Sapphires Mined in Madagascar?
Small-Scale Mining
A large part of Madagascar's mineral industry is based on artisanal and small-scale mining. Instead of enormous industrial mines, many gemstones are recovered by individual miners or small groups using relatively simple equipment. The work can involve digging through soil and gravel, removing unwanted material and searching carefully for pieces that may contain gemstones. Mining conditions vary from one deposit to another. At Ilakaka, miners heavily worked the easily accessible near-surface sapphire resources during the early years of the rush. USGS reported that production later declined as near-surface resources at Ilakaka and Sakara became depleted.
Deeper Deposits
The search for sapphires did not simply stop when the shallow material became harder to find. The USGS reported new sapphire resources at Ilakaka, about 26 metres below the surface. The report noted that developing deposits at such depths could require mechanical mining rather than the simplest forms of hand digging. This gives an idea of why sapphire mining can become physically demanding. A gemstone that looks tiny once it has been cut may have required the removal of a considerable amount of earth before it was found.

What Makes Madagascar Sapphires Special?
One reason Madagascar sapphires attract attention is their range of colours and qualities. Blue is the colour most people associate with sapphire, but natural stones can also appear in yellow, pink, purple, green and other shades. Some Madagascar sapphires can also display attractive colour combinations and unusual tones.
The final appearance of a gemstone depends on several factors, including its chemistry, crystal structure, inclusions and treatment. Two rough stones from the same mining region can therefore look entirely unique after cutting and polishing. For buyers and collectors, the origin of a sapphire can also be an important part of its story. A stone identified as coming from Madagascar connects the finished gem to one of the island's many geological regions.
The Human Side of Sapphire Mining
This situation is particularly relevant to Ilakaka. The sapphire discoveries brought enormous attention to an area that had previously been far less prominent. The history of the town is therefore closely tied to the rise and changing fortunes of the gemstone trade. It is worth remembering that statistics about gemstone production are not as precise as statistics for large industrial mines. The USGS specifically notes that gemstone production is difficult to estimate because the industry is fragmented, government reporting can be limited, and gemstone quality varies considerably.

Is Madagascar Still Mining Sapphires?
This is an important difference. Ilakaka has been a giant influence on the history of Madagascar's sapphires. But Madagascar's sapphire trade isn't tied to one mining area. Output has grown over time, as older deposits have declined in productivity and new deposits have been added. For example, the USGS cited new deposits discovered at Bemainty in 2016 that helped offset declining production at Ilakaka and other places.
Ilakaka's Place in Madagascar's Gemstone History
Yet the story did not remain frozen in the 1990s. Deposits change, mining becomes harder, new areas are explored, and production rises and falls. That is what makes sapphire mining in Madagascar such an interesting subject. The gemstones themselves may be small, but the industry surrounding them has shaped communities and attracted international attention for decades.

Frequently Asked Questions
Where is sapphire mined in Madagascar?
Sapphires have been mined in several parts of Madagascar. Ilakaka and Sakara in the south-west became particularly important after major discoveries in the late 1990s. Other deposits have also contributed to national production.
When were sapphires discovered at Ilakaka?
The major Ilakaka and Sakara sapphire deposits became important in 1998 and 1999, following the discovery of the Ambondromifehy deposit in 1996.
How deep are sapphire mines in Ilakaka?
Mining depth varies. USGS reported sapphire resources at approximately 26 metres below the surface in Ilakaka, where deeper mining may require mechanical equipment.
Is Madagascar still producing sapphires?
Yes. The USGS estimated that Madagascar produced about 2,100 kilograms of sapphires annually from 2021 through 2024. “These figures are estimates for the country as a whole, not just Ilakaka.
What other gemstones are found in Madagascar?
Madagascar produces several gemstones besides sapphire, including ruby, emerald, garnet, tourmaline, amethyst, and labradorite.

Conclusion
Sapphire mining changed Ilakaka from a relatively quiet settlement into one of the best-known gemstone mining areas in Madagascar. The discoveries of the late 1990s brought miners and traders to the region and established Madagascar as a key player in the international sapphire trade.
The industry has changed since those early discoveries. Some shallow deposits became harder to work, new deposits were found elsewhere, and mining methods have had to adapt. But Madagascar is still a major source of sapphires.
Sapphire mining in Ilakaka is a remarkable reminder for the gem enthusiast that a little stone can have a surprisingly big story behind it. Before a sapphire reaches a jewellery shop, it may have come from a remote mining area, passed through the hands of several people, and travelled a long way from the soil of Madagascar.
