4.31CT EMERALD CUT MONTANA SAPPHIRE, TEAL BLUE GREEN, 9.39X6.91X6.8MM. This is an amazing large teal sapphire- very rare for Montana origin! It is an older stone, acquired from an estate with several large, old Montana sapphires. We love this stone for it's classic step cut shape and vivid teal blue. There are some earthy inclusions visible to the naked eye, but our nature lovers won't mind! It's a great opportunity to own a rare stone, mined and cut in the USA.
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.
