Check the Cut

Whatever is the cut, you should check the transparency of the stone. It should have smooth edges with good symmetry throughout the surface.
Know About the Enhancements and Treatments
The majority of cornflower blue sapphires are heat treated to improve their color and appearance. These treatments ensure stability and higher clarity.
