    Sapphire – Natural, Faceted, Blue, 0.80 ct

    A very pretty blue Montana sapphire that shows an almost tanzanite-like color shift toward purplish blue under incandescent light. Not sure why video looks so greenish. Photo is much more accurate. Color: Bright Cornflower Blue, Treatment: Heat Only, Cut: Fancy Round Brilliant, Weight: 0.80, Dimensions: 5.52.
