Blue Sapphire, 1.03 ct Faceted from Tanzania

This is an untreated Songea sapphire that has a mild color shift from more of a medium very slightly greenish blue in daylight to more of a purplish blue under incancescent light. I've cut this one with a kind of opposed scissor design on the crown. Color: Blue Shifting to Purplish Blue, Cut: Emerald with Opposed Scissors Crown, Weight: 1.03, Dimensions: 4.7 x 6.2 mm.
