1.57CT OVAL MADAGASCAR SAPPHIRE, DEEP OCEAN BLUE TEAL, 6.86X6.10X5.12MM. We assume this sapphire has been heated, a permanent treatment for color and clarity. It has some light silk, visible in these magnified photos.

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.
