The colour of a 1 carat blue sapphire is what really makes it spectacular. Vibrant and rich colors—from a captivating cornflower blue to a royal blue that conjures the night sky—are the most sought-after shades. Even in this carat weight range, value can be greatly affected by little colour changes. The attractiveness of a 1 carat blue sapphire is further enhanced by its remarkable clarity, which indicates few imperfections or defects. Occasionally, inclusions may appear as tiny silk strands that give the stone some unique characteristics.
