Mark Twain,
Following the Equator: A Journey Around the World…
“ A very light straw color is their commonest tint. It seemed to me that these uncut gems must be more beautiful than any cut ones could be; but when a collection of cut ones was brought out, I saw my mistake. Nothing is so beautiful as a rose diamond with the light playing through it, except that uncostly thing which is just like it—wavy sea-water with the sunlight playing through it and striking a white-sand bottom. ”
