Nice Sapphire here, purchased directly in Thailand by a friend.  Unique color.  Definitely on the darker end but has good color in lower lighting environments.  This Sapphire comes with the pictured certificate, which is not from an official gem lab but is nice to have.

I    took pictures of this stone in high magnification against a   white background   to give    you the best idea of color and quality.    As a certified   gemologist I can verify that the above description is         accurate and   that this stone/stones have been tested in the gem lab to    verify    identity and natural origin.
