A new study conducted by the "University of British Columbia" reveals that Baffin Island Nunavut is home to cobalt-blue spinel which the study co-author says is "a ridiculously rare gemstone," as reported by CBC News.
The unique geography of Baffin Island allowed the spinel to form "1.8 billion years" ago when temperatures of approximately 800°C caused transformations and mixing of mud and magnesium-rich limestone under high pressures.
