Shan-konzan, Chaung-gyi, Mogok Township, Pyin-Oo-Lwin District, Mandalay Region, Myanmar
Just beside the Chaung-gyi creek adjacent to Shan-konzan village, the mining area of Shan-konzan (Shan settlement) is situated. In 2001, two joint venture gem mines using lebin-dwin methods recovered blue sapphires and fewer rubies in the alluvium. Most of these stones are of low-to-medium quality suitable for cabochons and usually weigh below three grams. Fine quality faceting-grade rubies and blue sapphires are rarely found. Spinel, moonstone, schorl, topaz, aquamarine, goshenite, lapis-lazuli, quartz, and almandine are also found. In May 1999 the mines were closed, but they re-opened in 2001.Ref: Ted Themelis (2008) Gems and Mines of Mogok, p. 185
