Natural Sapphire, 1.89 ct, No Heat, Oval Cut, Blue – ALGT Certified This natural sapphire weighs 1.89 carats and is cut into an oval mixed cut, displaying a fine blue and is eye clean. The stone measures 8.54 x 6.64 x 3.58 mm, resulting in a length-to-width ratio of 1.29, a balanced proportion well suited for bespoke jewelry design. The report confirms no indication of heating, a highly desirable feature since most sapphires on the market are routinely heat-treated to enhance color and clarity.
