    The best cuts for a blue sapphire are said to be oval, round, and cushion. The look of an oval-cut sapphire is similar to that of a round sapphire. The slightly extended shape, on the other hand, can make it appear larger than a similar-weight stone. A round cut is one of the most traditional shapes, and it helps a gem dazzle to its full potential. The presence of about 58 facets results in a large amount of light being reflected. Cushion cut, sometimes known as the 'pillow-cut,' has been popular for generations due to its cushion-like appearance. The gemstone has a rectangular form with soft, slightly rounded corners in this cut. Typically, the crown has 58 to 64 big facets. These cuts were popular in numerous forms of jewelry, including rings, pendants, and earrings. Find a wide variety of blue sapphire jewelry on 1stDibs.
