 A total of 31 ruby and sapphire occurrences have been confirmed in the Fiskenaesset/Qeqertarsuatsiaat district.One of these occurrences, Aappaluttoq (), is being developed for a potential mining operation.When European scientists first arrived in Greenland over 200 years ago to study the geology, they encountered native Kalaallit (Greenlandic Inuit) people who were already familiar with the red gemstone ruby.
