Natural fancy-color diamonds are judged through hue, tone, saturation and colour distribution, alongside cut and clarity.
Read the full colour description
Modifiers matter. Greenish yellow, pinkish orange and brownish pink describe different colour relationships. The visual result can vary even within the same laboratory wording.
Cut and colour work together
Historic cutters did not optimise colour in the same way as modern fancy-colour specialists. Antique faceting can produce distinctive areas of concentration and softer transitions that collectors value.
Documentation and treatment
Request a recognised laboratory report confirming natural colour origin. View the stone in neutral light and ask whether any additional origin or treatment documentation accompanies it.
