Between 2011 and 2017 the Geological Survey of Denmark and Greenland, Copenhagen & Nuuk (GEUS) has evaluated the Greenlandic rubies as part of a collaboration project with and commissioned by the Ministry of Mineral Resources in Nuuk, Greenland. The investiga-tions are mainly focused on characterisation of the Fiskenæsset complex (FC) ruby/sapphire, where a ruby mine is currently in operation at the most promising ruby outcrop in that area, Aappaluttoq, by the Greenlandic-Norwegian company Greenland Ruby. The license for this area was earlier held by the Canadian-Greenlandic company True North Gems Greenland (TNGG). The results for samples from the FC have been compared with samples from other areas in Greenland and abroad with the aim to find the characteristic fingerprint for the FC samples and to understand the ruby-formation process in the FC with the aim to find similar areas with rubies in the future. A pilot project was performed in 2010 by Per Kalvig and Dirk Frei from GEUS. Their samples have been re-analysed and re-interpreted and are included in this report.
