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.

Spinel is typically found in Vietnam, Cambodia, Kenya and the limited and sporadic occurrences of this gemstone make it highly valued by gemologists and jewelers. Canada is not typically recognized as a source of these rare gemstones, particularly those with such vivid colors and could be a region of potential interest for mining companies.
The study observes 14 occurrences of spinel on "Baffin Island" and reports that the geography of the region contains all the right factors that are needed to produce these gemstones. The two cobalt blue spinel samples were found in rock that was relatively well exposed and did not require extensive digging.
