2.77CT OVAL MONTANA SAPPHIRE, GIA, COLOR CHANGING GREYISH VIOLET TO PURPLISH PINK, UNHEATED, 8.31x6.32x5.84MM. This spectacular, one-of-a-kind 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 purplish pink. The stone also has great clarity, sparkle and brilliance, especially for a Montana Sapphire. We adore the amazing purple coloring in this modern cut!
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.
