Land of Origins: A Gemological Expedition to Ethiopia
In March 2018, a team of four GIA gemologists and videographers traveled to Ethiopia to visit its gem sources. The first target was the sapphire deposit in the north, followed by the opal mines in the central highlands. The last area visited was near Shakiso to witness the developing emerald mines.The gemstone mining sector in north central Ethiopia is the least researched sector because it is relatively a recent economic activity in the region. There is no research conducted on opal mining and its impact in this part of the country.

Gemstones are extracted in various ways that fall in into two wide categories: large-scale gemstone mining (LSGM) and artisanal small-scale gemstone mining (ASGM).6 The latter is the practice of producing varieties of precious stones using rudimentary tools and mechanisms often under dangerous conditions, within 20 m of the surface.Although the academic and official literature on artisanal small-scale opal mining (ASOM) has primarily focused on the loss of wealth owing to a lack of skill and its traditional nature, this study explores the multidimensional insecurity that the discovery and mining of opal stones in the Delanta wereda of Wollo has brought about.Artisanal small-scale opal mining (ASOM) insecurity in the
