Mined and faceted in the USA. This sapphire has been heated, a permanent treatment for color and clarity. Like most Montana sapphires, this stone will shift in color depending on the light available from more blue to more blue-green. 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.
