Bangkok Gems News: A Diamond Boom Amid Tariff Turmoil
Bangkok’s polished diamond trade is shining brighter than ever as a flood of Indian wholesalers reroute rough stones to Thailand for finishing—seeking refuge from punitive U.S. tariffs that have begun to fracture India’s polishing supremacy. With U.S. duties on Indian gem and jewellery exports surging from 25 percent to 50 percent by late August 2025, the economic calculus has fundamentally shifted. Indian hubs such as Surat and Saurashtra are reeling under mounting job losses and evaporating orders, while Thailand is emerging as the go to polishing haven.

Surat’s Struggles, Bangkok’s Opportunity
India’s diamond polishing powerhouse, particularly in Gujarat’s Saurashtra region, has endured a devastating blow: nearly 100,000 workers laid off as small polishing units shutter amid a pandemic of cancelled U.S. orders. Many affected artisans have tried pivoting to the lab grown diamond segment—but are now encountering the same tariff headwinds there as well.
Enter Bangkok: with significantly lower tariffs (around 19 percent compared to India’s 50 percent), Thailand offers an attractive alternative. Bangkok’s gem district is suddenly bustling, as Indian clients—and even investors—look to shift processing operations into Thai hands.
Infrastructure Ready for a New Wave
Thailand isn’t new to the gem scene. Bangkok has long operated within robust regulatory frameworks such as the Kimberley Process and boasted established polishing labs, logistics channels, and export infrastructure. But now, these assets are gaining new relevance as capacity ramps up to accommodate the influx.
Skilled Thai polishers are being enlisted, partnerships formed, and facilities upgraded—all to handle an uptick in rough stone inflow from India.

Anecdotal industry buzz highlights that Indian traders are quietly negotiating joint ventures with Thai polishers. Whether through contracts or equity partnerships, the goal is clear: keep polished exports to the U.S. afloat despite the tariff surge. As Indian domestic output falters, Thailand’s polishing share is growing—just as U.S. demand faces higher consumer prices and longer delivery times.

Thailand’s Polishing Industry Accelerates
As India’s polished exports decline—cut and polished diamond exports fell by nearly 17 percent year on year to $13.2 billion in FY 2024–25—Thailand is positioning itself to capture market share. Key Thai firms are expanding, securing diamond sourcing, and training polishers. Some are even collaborating with non-U.S. distributors to reroute polished diamonds through third-country channels—preserving access to U.S. demand amid tariff turbulence.
The Stakes and the Strategy
The opportunity is vast—but so are the challenges. To ride this wave successfully, Thailand must ensure consistent quality control, uphold certification standards, and navigate supply chain complexities. Currency fluctuations and shifting global demand could still pose hurdles down the road. Yet if Bangkok sustains infrastructure investments and strengthens ties with Indian partners, it could redefine the regional—and possibly global—polishing ecosystem.
Thailand now stands at a crossroads: firmly in the spotlight as Indian polishers race to preserve access to U.S. markets. Bangkok’s polishers may well find themselves at the center of the global trade spotlight in 2025, poised to reap gains others weren’t ready for.
Thai craftmanship in diamond polishing is unparalleled and labor cost is almost similar to India these days.
