The “Red Treasure” of Vietnam

Phuong Thu Lê is a third-generation Vietnamese gemstone trader. Her grandfather brought her father, Le Van Hoan, to the famed Luc Yen mining area as a teenager. There, they started a small gem trading business in the late 1980s.

Phuong and her family decided to name their exceptional 6.91-ct unheated pigeon’s blood ruby the “Red Treasure” of Vietnam. It was cut from a 10.87-ct rough from the Billion Hill mine in the Nghe An Province, a few hundred kilometers southwest of Hanoi.

Burmese vs Vietnamese Rubies

When describing the “Red Treasure,” fifth-generation Mogok ruby dealer Miemie Tin Htut of Silken East Co., Ltd. in Bangkok commented:

This 6.91-ct Vietnamese ruby is very reminiscent of the highly fluorescent, vivid pigeon’s blood red colors produced from the renowned Baw Lone Gyi mine in Mogok, Burma.
