Sapphire – Natural, Faceted, Blue
A sparkling Montana sapphire with a moderate color change from being a slightly greenish blue in natural and some artificial light to a purplish lavendar pink color under incandescent lgiht. This is an untreated stone that is so bright I actually saw spots after trying to look at it in direct sunlight. Color: Slightly Greenish Blue to Slightly Purplish Lavendar Pink, Treatment: None, Cut: Portuguese Brilliant, Weight: .91 Ct., Dimensions: 5.73.
