3.31CT HEXAGON MONTANA SAPPHIRE, MIDNIGHT OCEAN BLUE WITH TEAL FLASHES. MEASURES 9.9MM TIP TO TIP AND 8.71MM EDGE TO EDGE. The amazing clarity, large size, rich color and perfect cut of this hexagon Montana sapphire make it such a rare find and a welcome addition to anyone's jewelry collection or as an engagement ring. This stone is heated to improve color and clarity, and as you can see in photos the sapphire is totally eye-clean (not easy to come by in Montana Sapphires). There is some variation in color present when viewed upside down but the color appears even when right side up. This would look great in a low profile setting with side stones!


About Heat Treatments: Some colored gemstones are routinely heated for color and clarity improvement. This is a permanent treatment and typically only involves heat and not chemicals. The treatment mimics what the earth does naturally to gemstones as they reach the surface. If the stone says "Unheated," it is not treated in any way.
