Fancy White Diamonds are diamonds that have a milky, snow-like colour to them. According to the Diamond Source in Virginia, these diamonds “contain a high concentration of submicroscopic inclusions that scatter light” causing the milky colour inside the diamond. Although these stones do not sparkle and shine like a “colourless” white diamond, these diamonds can still be quite beautiful. Because of their rarity, these diamonds can become quite pricey. For these diamonds, the milkiness is considered a valuable aspect.

Opalescent Diamonds

Opalescent diamonds have a milky colour and are similar to fancy white diamonds. Like the fancy white diamonds, the milkiness is what makes the opalescent diamonds rare, but these diamonds are not just white. The way the light hits the stone causes different colours such as pinks, yellows and blues to be seen in the diamond. Although very rare and often expensive, these diamonds are not the same as coloured diamonds that come with an even higher price tag.
