5.06 ct Color-Change Sapphire
I think this huge sapphire would be a perfect gemstone for a gent's ring with its strong color change from dark burgundy reddish-purple indoors to a deep bluish-green in outdoor lighting. The color change is very similar to that of an alexandrite. Flawless clarity, and unheated with GIA cert.
