Gemstones have been found in Greenland, including diamond, ruby, sapphire, kornerupine, tugtupite, lapis lazuli, amazonite, peridot, quartz, spinel, topaz, and tourmaline.
The Kitaa Ruby rough, 440 carats of gem and near-gem material, was discovered in 2005 by True North Gems. It was believed to be the largest ruby found and documented in the Western Hemisphere. True North Gems chose to commission British Columbia sculptor Thomas McPhee to carve it. The design marries Greenland's Inuit traditions with its Norse heritage. The carved weight is 302 carats and took more than ten months to execute.
