Do you Know about Diamond Colour ?
Diamonds with increasing shades of brown and yellow are referred to as champagne diamonds, and diamonds with exceptional color, such as pink, red, green, blue, and amber, are called "Fancies." With the exception of some natural fancy colors, such as blue, pink, purple, or red, the colorless grade is the most rare.
The rarest and most prized diamonds are those with no hint of color at all whose beauty is entirely dependent upon their optical properties
