| There are akoya pearling operations in Vietnam, but they have yet to garner much success. From what I have heard from Chinese pearl farmers in South China near Vietnam, the material coming cross-border is too cream-yellowish.
Vietnam has also harvested freshwater pearls is Lake Ho Tay, the biggest lake in Ha Noi. But I have not heard of anything from the region since the mid-nineties, and I understand that the lake has become so polluted that culturing high-quality freshwater pearls has become impossible.
Melo-melo pearls have also been found in Halong Bay, but these were natural occuring calcareous concretions. |
