thanks for the interesting informative video

Fascinating. Are those rubies just as clean and suitable for jewelry like the ones from Mozambique for example? Or are they more opaque?

[@VincentPardieuFieldGemology]

Yes, some of the rubies produced at Aaapaluttoq are indeed suitable for jewelry either as beads, cabochons and also faceted stones. Only a small minority were preserved intact as specimens.
You can actually see stones for Jewelry from the Aappaluttoq ruby mine on www.greenlandruby.gl and on ruby.gl and on

Does heat treatment heal the fractures in the ruby? Pretty awesome discovery. You should do a video on how they mine the rubies and also how they extract them from the rock

[@VincentPardieuFieldGemology]

Yes, the reason why rubies from Greenland benefit from heat treatment is that heat treatment will (when it is done with borax) heal the fractures and also (when it is done in oxydizing conditions) make the stones brighter and remove the possible purplish overtone common in iron rich stones. Furthermore heat treatment can also help to remove some of the milky aspect of these rubies.
Hoping that will help,
