Gorgeous 1.6 carat Paraiba Trillion, measuring 8.5 x 6.9 x 4.8mm. Untreated, and absolutely gorgeous color that is 10 times more beautifulin person!! It has that rich, ideal carribean aqua color, is incredibly sparkly, untreated, and Mozambique origin. The 2 sapphires are oval cut, Nigerian Origin, and average around a half carat each carat each. Treatment has not been confirmed, but I believe 1 may be heat treated. Beautiful, dainty, and a lovely contrast to the Paraiba they are paired with.
