In the normal diamond color range 'Z' is classified as most tinted while 'D' is classified as most colorless. So what happened to A, B and C? Are they reserved for new diamond discoveries?

Fancy colored diamonds are very rare to find in nature. They represent less than 0.01% of diamonds mined in the world - or, about 1 in 10,000. Furthermore, nature produces some colors with far more frequency than others, so a diamond transmitting your favorite color might be, literally, 1 in a million.

Gold and gemstone prospectors work the streets of New York's illustrious diamond district, but you might not recognize them at first. Kneeling, gloved, scraping and brushing, they could be mistaken for pedantic street cleaners but don't be fooled. Historically some Big Apple prospectors have claimed over $300 per day in "paydirt."
