The gem deposits so far identified are of two types as primary deposits and secondary deposits. Both traditional gem mining and mechanical gem mining are the methods been used in the process of gem extraction in the country.

 Environment pollution
Although mining provides people many needed resources, the environmental costs can be high. Surface mining clears the landscape of trees and soil nearby streams and lakes are inundated with sediment. Pollutants from the mined rock, such as heavy metals, enter the sediment and water system. Acids flow from some mine sites, changing the composition of nearby waterways.
