Blue diamonds, its says it is natural yet treated with heat?

I have no clue on how diamonds are processed whether it be natural or artificial or treated to add colour or anything. Can anyone shed some light on this topic please?

Color in diamonds comes from the traces of elements that have managed to weasel their way into the diamond's Crystal lattice structure. In the case of blue diamonds, it's usually hydrogen or boron replacing the carbon. A more "pure" diamond would have no color. Blue diamonds can occur naturally, but it would take a gemologist to determine whether those are real or synthetic.
Since these are supposedly from Africa, I would be a little concerned about exactly where they came from and if they are products of "blood mining" operations. The best way to ensure against getting those is to buy vintage gems.
