A massive 11,000-carat ruby has been unearthed in Myanmar’s war-scarred gemstone heartland

BANGKOK -- Miners in Myanmar have discovered a rare ruby of enormous size, considered to be the second-largest by weight ever found in the conflict-battered Southeast Asian nation, state media reported Friday.

The ruby, measuring 11,000 carats (2.2 kilograms, or 4.8 pounds), was unearthed near the town of Mogok, in the upper Mandalay region, the heartland of the lucrative gem-mining industry that has recently experienced intense fighting in the country’s wide-ranging civil war.

According to a report from the state-run Global New Light of Myanmar, the newly found rough ruby was discovered in mid-April, just after the traditional New Year festival.

While it weighs roughly half the weight of a 21,450-carat (4.29 kilograms, or 9.45 pounds) stone found in 1996, the new discovery is considered more valuable due to its superior color and quality. It is described as having a purplish-red hue with yellowish undertones, a high-quality color grade, moderate transparency and a highly reflective surface.

Myanmar produces as much as 90% of the world’s rubies, primarily from the areas of Mogok and Mong Hsu. Gemstones, both legitimately traded and smuggled, are a major source of revenue for Myanmar. Human rights activists and organizations such as the Britain-based research and lobbying group Global Witness have urged jewelers to stop purchasing gems sourced from Myanmar, as the industry has served as a vital revenue stream for its military governments over several decades.

A new, ostensibly civilian government was installed this year, but it followed elections described by human rights and opposition groups as a sham. The vote returned to power President Min Aung Hlaing, the army chief who led the most recent military takeover in 2021. He and his Cabinet recently examined the giant ruby at his office in the capital, Naypyitaw.

Gemstone mining also serves as a primary source of funding for ethnic armed groups fighting for autonomy, a factor that has helped fuel decades of internal conflict.

The security of these mining regions remains volatile. Mogok was captured in July 2024 by the Ta’ang National Liberation Army, or TNLA, a guerrilla force representing the Palaung ethnic minority. Although the TNLA took over and operated the mines, control was eventually transferred back to Myanmar’s army as part of a China-mediated ceasefire agreement concluded late last year.
