Hello PSers,
I''ve been lurking on the forum and website for a while learning about some of the more advanced topics, and now I need help with a purchase that I need to make soon. First, though, I think it might be worth giving a little back story. You all will have to forgive the story, but you won''t understand the context of my current purchase without it. I also apologize for the length of this post.
In the spring of 2007, I purchased a ring from a local retailer, but I purchased the center diamond from Blue Nile. I don''t remember how much it cost, but it was a .52 ct, G, SI1, excellent cut, EX symmetry, and VG polish. It''s a beautiful stone and is probably the sparkliest thing I''ve ever purchased. Before I bought it, I had done a good amount of research, and I felt like if I got an excellent cut, then I could still get a great stone in the G-S1 area and save some money. The e-ring was a designer that she wanted, and it had about 50 to 60 points worth of pave, side, and surprise diamonds. So total carats-wise, she was looking at a little over a carat.
Unfortunately, before I proposed (at this point she didn''t know I had a ring), she decided that she wanted to break up (late spring). I will spare you all the sad, depressing details, and give you the main points. We ended up getting back together (late summer), but at this point she had found out about the ring from her parents, who thought she called it off because she freaked out when I proposed (I had asked for her parent''s blessing in the spring, so they knew).
Up until lately, I have been a little apprehensive about the relationship, but I think I am good to go now. I wanted to upgrade the diamond, and I have a little extra money to spend on it now. I wanted to get a D-IF for all of the symbolic, and none of the practical, reasons. I understand the arguments both ways but I think this is what I want. I wanted a lightly larger stone so that it shows up a little better against the side stones, but it can''t be too much bigger or it won''t fit the mount, which had to be modified from a 1.0 carat size to the .5 carat size. I thought that a 3/4 carat might be the best option (she also initially didn''t like the ones larger than about 3/4 carat). I also kind of want the new diamond as a mental fresh start for me. I''ve been searching again, and I have returned to PS for more research, and I''ve come up on a few stones with which I need help.
1. .72, D-IF, EX, EX, EX, Strong Blue fluoro, 1.3 HCA
2. .70, D-IF, EX, EX, EX, Strong Blue fluoro, 1.0 HCA
3. .84, D-IF, Ex, Ex, Ex, Medium Blue fluoro, Haven''t run HCA yet (waiting on cert), but here''s what I have 61.4/57 6.09x6.06x3.73
The two strong blues are both also designated as H&A. All three are GIA certified. I have gone through some of the threads and there seems to be a back and forth on the fluoro, but it seems that most people that have actually seen the strong blues actually tend to like them a little bit more. From what I''ve read and heard, the blue flouro actually sounds pretty cool. I guess my main concern is potential problems with the value of the strong blues if she were to want to trade them or sell them later. The supplier confirmed that the strong blues don''t have any of the haziness or milkiness or whatever that ruins some strong fluoro diamonds. On the other hand, the reason that I still have the .84 in the running is that I kind of also wanted to reach the numerical .75 threshold from a mental standpoint even though a .72 is still technically considered a 3/4 carat.
Also as a secondary matter, with the H&A''s, she wouldn''t be able to see the pattern unless the stone was loose. Ladies of PS, if you were given an H&A, how would you feel about getting it loose with a scope so that you could see the H&A pattern? After the proposal, the diamond could be set. I know it''s not traditional, but she would get to see the cool H&A''s.
Lastly, you might have noticed this as you read through this post, but I feel like some of my rationale might be inconsistent at times. For example, I want the D-IF, but I am willing to go with the blue fluoro? I can''t explain that. Please help

Thank you all for taking the time to read this, and again, I am sorry for the long post!
