Do you have a video of the stone? I find you can tell more from a video then from an aset.
Pear asets are not pretty...this one looks good in my book. However, I withhold judgement until I can see a video...
Does it matter that it will be going in a rose gold setting? I've heard that you can drop down in the colour scale based on setting. The difference in price between this I and an F is astronomical.Because the stone is very long it shows concentrated yellow towards the tip which will contrast with the near colourless central bright region.
I personally would stay at F for a stone like this and even then you will see a lot of yellow.
I'm not liking the look...what is your budget? I will post some pears that I think would be nicer. Pears in general do not return as much light as rounds,
nor do they sparkle as much as rounds. You need to find a really nice cut one and love them for their pretty pear shape. If you dont, then a different
shape may be better for you...FYI...I wear a pear ering.
Dont try to gain length by giving on the cut...especially when all its gaining you is more mush at the pointed end. You really want to see crisp, well defined
facets that return light well. When the stone turns you want to see the well defined facets stretch down towards the point end as far as possible and you
want the well lit facets to go up to the top of the rounded edge as far as possible.
Not finding much at JA in that size so I'm just going to post some pears that look nice so you know what to aim for (ignore size/color/clarity). I'm not
even finding all that nice of ones in other sizes.
