I recently purchased 150 grams of Tugtupite rough from Peter
Lindberg of Greenland on an ebay auction for $35. I’m not aware
of what the finished material is going for, but if you search
ebay for it, you will probably find him or others selling it.
The company is called Jewel Stones of Greenland, Box 57 3921
Nassaq, Greenland – sorry but I cannot find his email address.
