1.17CT BRILLIANT ROUND MADAGASCAR SAPPHIRE, COLOR SHIFTING TEAL TO PURPLE RED WITH OLIVE GREEN FLASHES, 6.65X3.70MM. Really unique stone! This round sapphire shifts in color from green-teal with olive flashes in natural outdoor light to purple grey with red in indoor lighting. It is eye-clean (no visible inclusions) and is presumed to be heated, a permanent treatment for color and clarity.

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.
