What does fancy yellow mean?
The familiar D-to-Z diamond scale runs from colorless to light yellow. Yellow diamonds with color beyond that range are described within the fancy color system.
The role of the cut
A colored diamond’s shape and faceting can influence how its color appears face-up. Radiant cuts, for example, can concentrate the appearance of yellow. Compare the finished stone, not just its measurements.
Choosing your shade
Ask to compare the diamonds in consistent lighting, then consider how the setting changes your impression. A laboratory report can help you understand the color description and whether the color is natural or treated.
