In natural sapphires, heated white sapphires can occasionally have subtle yellow or blue aspects. The entire brightness of the stone is enhanced by the methodical removal of these color flaws through heating. This method is entirely safe and long-lasting, while maintaining the natural hardness and durability of white sapphire. Due to its exceptional refractive index, the gemstone produces the captivating color play known as "fire" that shimmers within it by effectively bending light.
