This lovely unheated sapphire comes from Umba, Tanzania, and is a gorgeous rich blue. The gem is 100 percent natural and untreated in any way. This sapphire has slight inclusions that are just barely visible to the naked eye. The inclusions have been factored into the price, making this a great value for the size and color.
This sapphire is faceted in a modified version of the classic diamond round brilliant design that is optimized for sapphire; the result is a glittering beauty of a gemstone. It weighs 0.64 carats and measures 5.0 x 3.4 mm, the perfect size for an engagement ring.
