This Montana Sapphires is dynamite it is a color shift between two of our most popular colors. The aqua teal explodes in outside light especially any dispersed light like a cloudy day. Then it is a beautiful grey color inside which has been extremely hot lately. The stone is vs clarity but that doesn't distract at all from it's natural beauty. The Luster on this sapphire is incredible. This piece was faceted by Robert coggins and is 7.76mm
