Diamonds come in all colors, though most are white, with faint tinges of yellow. Completely colorless, "blue-white" diamonds are rare and very valuable,as are natural diamonds with "fancy" colors such as pink, red, canary yellow, blue, and black.
钻石有各种各样的色彩，虽然大部分都为白色，但往往带有微黄色的折射光。完全无色的“蓝白”钻最为罕见，因而也价值不菲。因为天然钻石通常都带有各种“美丽”色泽，比如粉色、红色、淡黄色、蓝色和黑色等。
