Ahhhhhhhhhhhhhhh, finally found someone who is on the same wavelength with me! I got myself a heart shaped diamond too for my upcoming proposal cuz round diamond is too mainstream hahaha.
Now allow me to answer your questions.
1. Me!!!
2. Fancy cuts cannot be compared one-on-one with round brilliants, as both their target audience is different. Round brilliants are for people who want the most bling, while fancy cuts are for those who are after the shape - pear, cushion, oval, heart, etc. Of course, one has to sacrifice sparkle and brilliance for these unique shapes. But that does not mean that you can settle for a badly cut heart shaped diamond. Even though a heart shaped diamond might not be as sparkly as its round counterpart, the stone will still sparkle if it is a well cut diamond.
3. To be honest, do not get a heart shape of less than 0.5 carat. Anything below 0.5 will make the heart shape indistinguishable and it will look like a badly cut round diamond even from close range. However, if you cannot go beyond that size due to budget constrains, one trick is to do a bezel setting. This type of setting will accentuate the shape of the heart beautifully. Also, try and get a heart shape with excellent symmetry cuz it is very important to have an exact mirror image of both halves of the heart. Otherwise, your heart will look cacat.
Ohh yes, one more thing. The L/W ratio of your selected diamond is 0.86, which is slightly fat, in my opinion. The ideal heart shape, or "happy heart" is somewhere between 0.90-0.92. A L/W ratio of above 0.93 will make it look elongated and thin, macam your heart shape tak cukup makan hahaha. These are more suitable for pendants. But this is more of a personal preference lahh. If you think that an elongated heart looks nice, by all means go ahead.
Looks like there is only 1 gentleman here who is like minded and thanks for elaborating on this. It would be impossible for someone to have no constraints to buy diamond unless you are Rosmah, which is a fairy tale.
Considering your thoughts of having a better carat, what do you think about this?
Although it does not have L/W ratio of 0.90-0.92, you've mentioned it is a personal preference. I think I'll set a date to have a look see look see in Jewelry shops to understand and appreciate them before making the call.
