1.10CT ROUND TANZANIA SAPPHIRE, COLOR CHANGING TEAL TO GREEN GREY, 6.00X4.14MM. Totally natural/untreated. We love the little "freckle" black inclusion in this stone! Shown in the magnified photos. It shifts in color from teal blue in natural light to purple grey indoors. Love the cut.

Stunning color-changing sapphire from Tanzania with one internal "bubble" like inclusion that can be slightly seen depending on the angle of the stone.

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.
