Phuong at the Sunday gem market in Luc Yen — certificates, loose stones and a tray of rings on the table.

I’m Phuong — it means phoenix in Vietnamese, so friends abroad call me Phoenix. I’m a second-generation gem trader. My family has bought and sold stones at the Luc Yen market since 1990, from the ruby-fever years to a remarkable cobalt spinel strike we sold at the mine in 2020.

Luc Yen is a mountainous district in northern Vietnam and the country’s most important source of colored gemstones — ruby, red spinel, and the world’s only meaningful source of cobalt blue spinel. Most foreign buyers stop in Bangkok and never come this far. That is exactly why the finest Vietnamese stones so rarely reach the world with an honest voice attached. We are trying to change that.

How we work

On YouTube I test stones on camera in Vietnamese for 48,000 subscribers. Here, I do the same in English. And every Sunday I still face the same market women I have known for years — which is the real reason a reputation in Luc Yen is worth protecting.

“I’ll be facing the same market women next Sunday — reputations here are for life.”
