George Frederick Kunz,
The Curious Lore of Precious Stones
“ Its color is that of ice, and as the dewdrop or the drop of water from a mountain stream sparkles in the light of the sun, as the icicle sparkles in winter, and the stars on a cold winter night, so the diamond sparkles, and it combines and contrasts with all known gems. Like light, it illumines them just as the sun does the plants of the earth. The diamond, the gem of light, like light itself when broken into a spectrum, gives us all known colors, and by combining all these colors it gives us white. ”
