Not sure what this post is asking...?
Cushions & EC’s are fancy cut diamonds, and cannot be evaluated on certs/stats, alone.
Even static photos aren’t enough to evaluate a fancy cut diamond.
Cushions and EC’s have nothing in common; you’re comparing apples to bananas.
Which cut do you prefer over the other? Is this stone for you, or are you searching for someone else? If someone else, which is their preference?
These stones will perform very differently, so narrowing down preference will be helpful to begin evaluation...even comparison to others within those criteria, and budget.
Please request ASET images, and post videos of each/any stones you are considering for evaluation.
