This lovely unheated sapphire comes from Umba, Tanzania.  This sapphire is a color-change sapphire: Under fluorescent light and in daylight its a deep blue-violet color, while under incandescent light it changes to a deep purple color.  While the macro image shows some crystal inclusions, these are not visible without a loupe; its an eye clean gemstone.  There is some light rutile silk that makes the gem a bit “sleepy” and it has been priced accordingly. The gem is faceted in the classic round brilliant design; it weighs 1.19 carats and measures 6.3 x 4.0 mm.
