light performance for a colored diamond is showing even color. For that I would give it a c+ because the color is uneven.
In other lighting it might show up, but whats the point of heart shaped facets if they do not show up in the face up patterning the majority of the time?
For that it gets a F.
Now lets say one did get a heart pattern to show up, it would be much more visible in larger sizes and a bit of a disappointment at smaller sizes.
Just my opinion.
Thanks… didn’t link because it is Etsy. Agree that the heart would be really hard to see without a loupe. I would have loved the romanticism when I was younger, though.
