This is a really interesting color combination for a Montana sapphire teal on both sides of the stone and yellow in the center. The clarity is SI there is a small spot shown in the photo in the center. The flaws don't take away from this stone at all its all about color and this sapphire has that in spades. It measures 11.7x5.5mm The cut is good and the luster is brilliant on this one. 1.96ct TEAL YELLOW MARQUISE BI-COLOR MONTANA SAPPHIRE
