1.46CT ROUND SONGEA SAPPHIRE, COLOR SHIFTING GREEN TO GREY, 6.66X4.64MM UNTREATED. Totally natural/untreated. Light silk, doesn't detract from the beauty of the stone as it only shows from certain angles. The cut is a little uneven on this one, cut by hand. Beautiful shifts in color from grey in indoor lighting to green outdoors.

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.
