2.70CT ROUND MONTANA SAPPHIRE, BLUE, 8.34MM. We bought this stone right from the miners! It's a huge, rare size for a Montana origin sapphire and is a fun, earthy blue stone. Changes from blue to blue grey depending on the lighting. This stone is heavily included, which is reflected in the price. They are white crystal inclusions, no black. It may be a heated 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.
