Come share share what did Jann Paul say about evaluating Heart shaped diamonds

I am sure some bros will prefer something other than round brilliant.
The shape of heart shaped diamonds or generally, fancy shaped diamonds are more of a personal preference. Some prefer it to be slightly elongated, while some prefer a slightly plump shape. Unlike round brilliants whereby they have a set of strict requirements, fancy shapes do not. This is because the stone is cut for its shape and not to maximise brilliance. As long as the viewer finds it sparkly and likes the shape of the cut, then he/she is fine.
In particular for heart shapes, JannPaul recommend the slightly plump version, or what they call the "happy heart". It does give the illusion that it looks bigger carat for carat compared to an elongated heart.
In terms of the 4Cs, it is advisable to get 0.5 carat and above and not less than F VVS. As heart shapes do not have as much light return as rounds, body colour and inclusions cannot be masked as easily. This I have to agree with them cuz I personally compared a F colour and a G colour heart shaped diamond, and the difference is very much distinguishable even under LED lighting.
So there you go folks. My humble findings on heart shaped diamonds. Hope this helps you guys in searching for your own fancy shapes.
