COLOR
Most diamonds are seemingly colorless, but when carefully observed and compared, differences can be seen between them (from colorless to yellowish or brownish tones).
Generally, with the exception of those considered “Fancy colors”, the more colorless a diamond is, the more valuable it is. This is usually classified according to several scales:
