A very hip Montana Sapphire with a Color Change from faint Blue or Green outdoors (photos) to just a blush of lavender under fluorescent lighting!  Both hues are light, so she will appear nearly colorless at times as well.  A few tiny inclusions, not visible without magnification. Ideal size and shape for an engagement ring!
