 Blue sapphire’s mesmerizing blue colour comes from trace elements of titanium and iron in the corundum. The shade and intensity of the blue colour can vary, with the most sought-after hue being a deep, velvety blue with a slight violet undertone. Heat treatment is a common practice in the gemstone industry to enhance the colour of blue sapphire.
