The terms 'Champagne', 'Cognac' and 'Coffee' refer to different types of brown diamonds. In the diamond processing/dealing industry, the word 'Brown' is considered a killer as far as diamond value goes. Even though champagne is a light yellow colour, champagne diamonds are Light Brown. Cognac is usually used to describe a diamond that is Orangish-Brown because cognac is a deep golden-orange colour.
These are NOT our manufacture (probably Russian) and NOT 'Canary' in colour
