Question: what is the difference between a white sapphire and a diamond?
Answer: White sapphires are generally duller than diamonds and can even appear milky or cloudy. White sapphires exhibit less sparkle and a lower refractive index at 1.77(whereas a diamond's is 2.4). The beauty of the sapphire is in its very whiteness and the color of the body. A beautifully cut white sapphire.
