In stock


This lovely unheated sapphire comes from Umba, Tanzania.  The color is a beautiful medium violet-blue color. The sapphire is very clean and as a result it is quite bright and lively in the hand; while the macro image shows a tiny feather near one end it is not visible in the hand without a 10x loupe (and will be hidden under a prong when it is set). The gem is faceted in a classic emerald cut design; it weighs 1.16 carats and measures 6.6 x 4.7 x 3.6 mm.
