Kakortokite consists of arfvedsonite (nearly black) nepheline (off-white) syenite, containing sporadic red eudialyte grains. It is used to make cabochons and takes a polish well. Similar rough has been marketed as “Lopar’s Blood” from Alaska.
Not a well known gem stone, it has met with great success at the Tucson show and will become another very desirable gemstone from Greenland. Currently going through name changes due to the difficulty of pronunciation of Greenlandic names by the gem industry.
