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.
