This lovely unheated sapphire comes from Umba, Tanzania. The color is a beautiful steely blue and is consistent even as the lighting changes. There is a light touch of green noticeable at the ends of the oval if you look closely, but overall the color shows as strongly blue. While the macro image shows some rutile silk and tiny crystals in the gem, these are not visible without a loupe; its an eye clean gemstone and its very bright and lively in the hand. The gem is faceted in a classic oval design; it weighs 1.37 carats and measures 8.0 x 6.0 x 3.7 mm.
