2.57CT TRILLION MONTANA SAPPHIRE, COLOR CHANGING TEAL TO PURPLE GREY, UNTREATED, 9.29X8.31X4.57MM. We love the unique cut of this trillion/fat pear sapphire with an open culet at the center. It was mined in Montana, USA and shifts in color from a purple grey indoors to a teal blue in outdoor natural lighting. Special stone in a rare, larger size! Some visible silk inclusions.

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.
