RARE larger than 2ct size, these sizes are naturally hard to find from Montana! It has slight natural silk inside and is totally natural/untreated. This sapphire will darken indoors but is a beautiful, dusty blue and may show more purple/grey indoors in the absence of natural light. The cut of this oval faces-up to look larger than a 2.40ct 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.
