3.76CT OVAL MONTANA SAPPHIRE, GIA, GREY GREEN RED COLOR CHANGE, UNTREATED,12.01X7.79MM. 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 yellow to gray pink. Sometimes the sapphire appears grey-white as well to the naked eye- it's truly unique. The stone also has great clarity, sparkle and brilliance, especially for a Montana Sapphire. Anyone would be lucky to have this in their collection!

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.
