2.31ct ROUND MONTANA SAPPHIRE, GIA, COLOR CHANGING GRAYISH VIOLET TO PINKISH PURPLE, UNHEATED, 7.65X5.41MM. This fun Montana sapphire was recently cut into this modern oval brilliant shape from a rough crystal that had been in an estate for many years. Now it has new life, and a fresh certificate from GIA stating it is untreated/all natural and color shifts from grayish violet to pinkish purple. This sapphire has an indentation on the edge of the girdle, as shown in the magnified photo.
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.
