180CT ROUND MONTANA SAPPHIRE, TEAL BLUE GREEN, MEDIUM COLOR SATURATION. This is a spectacular precision cut sapphire, mined and polished right here in the United States. This sapphire comes from the Rock Creek deposit in Montana and is very clean/clear for a sapphire from the region, with some silk that is not visible to the naked eye. It's diamond-like cut helps the sapphire sparkle with intensity. It was heated to improve color and clarity, and measures 7.15mm round.
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.
