Blue sapphire is another highly valued gemstone, known for its exquisite blue color and durability. The most desirable blue sapphires display a deep, intense blue hue. The color can range from cornflower blue to royal blue, with saturation and tone playing a crucial role in determining its value. Sapphires can have inclusions (internal flaws). However, sapphires with fewer visible inclusions are generally more valuable. Sapphires are often cut in various shapes such as oval, round, cushion, and emerald cuts to maximize their color and brilliance. The cut can greatly affect how light interacts with the stone.
