I have really enjoyed learning about diamonds from this site. So much so I would like to continue my education in an informal way. Could any of you recommend a nice book that discusses diamonds and colored gemstones?
Renee Newman has a series of books on gemstones. She has one for colored gems, one for sapphires, rubies and emeralds and one just for diamonds. Nice photos and I found them very useful. You can find them in most bookstores.
