Round 1 Match 15
Stare into the deep blue depths. Which minerals is staring back?Mika McKinnon (Mineral Cup)
Sapphirine's type locality is in western Greenland, south of Nuuk, which is where the mineral was discovered in 1809 by Karl Giesecke.
It was named due to its blue color being similar to sapphire, a different, associated mineral (#corundum, aluminum oxide).
