Gem mining (ruby) started in 1991.
A distinctive feature of Mong Hsu ruby crystals is their deep violet (sapphire) core, which is surrounded by a red (ruby) rim. With heat treatment, the violet core becomes a deep red.

"The rubies from Möng-Hsu are generally unsaleable as mined. They usually must be heated, often to high temperatures ..." (Elements 5 (2009) p. 160).

NOTE: The grid reference is centered on Mt. Loi Hsaung Htao, where the majority of mining activity takes place. The mountain is situated roughly 14 km SE of Möng Hsu.
