"Clarissa, Volume 5 (of 9)"
Samuel Richardson
A very favourite colour is the pink, but in most cases this colour is not natural to the stone, but is the result of "burning," or "Pinking" as the process is called technically, which process is to raise the temperature of a yellow stone till the yellow tint turns to a pink of the colour desired.
