The Beluga spinel has an unusually intense blue colour with the chromophore (colouring agent) being cobalt.
|In 2002, gem quality blue sapphire was discovered in the Canadian Arctic, near the hamlet of Kimmirut.|
In late 2005 True North Gems discovered an extremely rare, cobalt-rich variety of spinel.
|Gemstone exploration, with the exception of diamonds, is not common in Canada. A decade ago, emerald mineralization was discovered in the Yukon, Northwest Territories and Ontario which generated a brief period of interest. |
There have also been sapphire discoveries in British Columbia, Nunavut and Ontario.
|These discoveries led to a number of scientific papers but gemstone mining remains a speculative and unfamiliar market for most.|
