This is my personal favorite sapphire in years Chris Wolfsberg cut this one and it's so good it's difficult to describe. The color is this beautiful blue with a yellow bi-color creating a frozen blue color. The luster is beyond incredible this sapphire has life and character that is seldom seen. The clarity is excellent vs there is one tiny spot at a certain angle that appears in the photo but it is extremely difficult to see in person. This Montana sapphire has been heated to bring out the beautiful bi-color nature. It measures 8mm this is more than just a sapphire this is a work of art. 3.53ct FANTASY CUT BI-COLOR ONE OF A KIND MONTANA SAPPPHIRE
