Here is a very beautiful 100% natural Montana Missouri River Sapphire.

As with most natural untreated Montana Missouri River sapphire, this is a color changer.

Indoor lighting, this amazing sapphire looks pale green, or it can look pale blue depending on the lighting type. 

In the sunlight the sapphire will pick up some blue from the sky and can look slightly teal.

The sapphire is eye clean, it has a few very slight inclusions that are only visible using magnification.

Has great sparkle and brilliance in most lighting.
