Comment: This cc sapphire comes from the mines in the Umba valley which are thought empty. Luckily we snatched up some from last year even well over one carat (though nothing much bigger). This 1.39 changes from a bright lake green-blue at day to a mild orange purple color at night. Clean, window-free, well cut and affordable. In most light setting the gem shows a charming mix or blue, green and orange/purple at the same time. All in pleasing pastel hues and good luster.
