Here is one beautiful, 100% Natural Montana Missouri River Sapphire. As with most untreated Montana Missouri River sapphire, this sapphire is a color changer.

Ok, so you are probably wondering about the color description? Well this beautiful sapphire when I first viewed it, due to the lighting I was in, looked almost black or very dark silver, but still had amazing brilliance. Once I was able to test it, I found it's true colors.

"Alexandrite Effect" is basically the ability for a gemstone to change color from Green to Purple (the most common alexandrite color change).

So as you will see in the photos, this sapphire looks almost white to silver, but it is actually a pale green as seen in some indoor lighting and outdoors. However in incandescent and some fluorescent lighting, the sapphire will look purple.

In one of the photos I have used a UV laser which clearly shows the presence of chromium by turning the sapphire a fire red. This can only happen when chromium is present.

This sapphire is very eye clean, even with a 10X loupe, it will be difficult to see any inclusions. 

As you can tell from these photos, the brilliance is very great on this gem, and it is dazzling in the sunlight, which made it about impossible to take photos of it outdoors.

These photos are taken at extreme magnification so you can see exactly what you are purchasing. This sapphire is much more beautiful than the photos show.
