Fig. JO4. Panorama view of the eastern part of l\/logok (location is marked on Fig. JO2). The area is scattered with alluvial mines for rubies, sapphires and spinels. Ohn Bin is another important area for Endings of collector gems, such as color-changing sapphire, taaffeite, chrysoberyl, green grossular garnet, colorless garnet and minerals of the amphibole group, such as edenite and even alexandrite. Like the Pain Pyit area, the Ohn Bin area attracts many gem dealers in their "hunt" for new rare gems. Both, Pain Pyit and Ohn Bin are situated at the margin of plutonic rock suites (Fig. JO3).
