Been doing a lot of research the past few days on diamonds, since I’m trying to get a good value for my girlfriends engagement ring. Learned about HCA, crown/pav angles, fluorescence, and all that good stuff beyond the four C’s. I’ve been able to narrow down my choices to a small list of diamonds. I found a particular diamond that looked good to me (on paper and on picture/video) and particularly good value but the fact that it is very discounted compared to similar diamonds is making me wary.
GIA number 1288988579
Table: 55%
Depth: 62%
Crown: 33.5
Pavillion: 41
HCA is 1.1
This diamond was listed on a few sites, and it was always a lot cheaper than the others on those sites, even cheaper than some lower color/clarity diamonds.
From the picture and videos, I dont see anything wrong with it, just that it has a strong fluorescence (and from my understanding, that’s not really a bad thing most of the time, but can make the diamond look hazy, but from the video, it doesn’t really look like there’s any haziness or milkiness).
Here is a pic and video of the diamond:

To me, from the video, it actually looks less yellow than other H color diamonds.
So just wanted to get some input from someone more experienced than me, have I found a great deal, or is there something I should be wary of?
