This lovely unheated sapphire comes from Umba, Tanzania. The sapphire has a soft glow to it as its filled with fine rutile needles. While it could be heated to clear it up and deepen the blue color, I believe its quite beautiful as is. Due to the fine rutile silk, I’ve discounted the price accordingly. The gem is faceted in the classic round brilliant design; it weighs 1.51 carats and measures 6.7 x 4.5 mm.
