Very large, precious, and rare untreated radiant cut Montana Sapphire mined in El Dorado Bar, Montana, USA. Some visible silk in the center of this stone, but the beautiful brilliant radiant cut makes it sparkle. We would call this a medium teal blue green, almost like Caribbean waters. The inclusions are more visible from some angles than others, as the stone turns and moves on the hand. Will look more blue grey indoors or on cloudy days, and shift to more teal green blue in brighter natural light. This stone is accompanied by a Preliminary Report #1228174 by NAGL (North American Gemological Laboratory) and retail replacement value of $13,575. 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.
