Sculptures of Light: The Artistry of Contrast explores the role of dark zone features in fancy-shaped diamonds and their influence on Visual Performance. Often misunderstood, contrast features are an impactful component of how diamonds create pattern and visual character. Through guided education, comparative analysis, and real-world examples, this presentation examines the wide range of dark-zone appearances across GIA’s grading scales. In addition to providing a sneak peek at GIA’s upcoming fancy-shape cut grade system, the session will explore the fascinating way intentional contrast anchors a diamond’s visual design, providing both dimension and space to its unique optical architecture.
