Diamond engagement advice

Hi there just want to ask advice 

I’m interested in buying a Tiffany and co engagement ring - I have the following options open to me 

1.01 d vs1 ( very good in cut, symmetry and polish) no fluorescent 

1.22 d vs1 ( triple excellent cut, symmetry and poise) medium blue fluorescence 

1.23 f vs2 ( triple excellent cut, symmetry and polish) no fluorescence 

Im sway towards the 1.22 d with fluorescence.. or am I making a big mistake! Please help

Whether you are making a mistake really depends on what you are looking for. Some pretty generic advice:

1) See the rings in real life, together - or at the very least the diamonds. Accept no excuses re: "it's difficult to get them together" - Tiffany is a premium service outlet, and you pay for it: let them work for the premium.

2) I would also trade off fluorescence against size and cut, which leaves the 1.01 last of my "paper ranking".

3) Far less sure about the 1.22 vs. the 1.23 - partly because you haven't shared one other critical element: price. Assuming price is equal, it's very challenging to see D vs. F colour differences in a realistic "everyday" scenario. On the other hand, fluorescence is not an issue for me (or for looks, in general, with MB), but it will make re-selling the diamond (should it ever come to that) harder, especially with a D. In the end, any recommendation between the 2 would really depend on how "excellent" the two cuts truly are. Can you at least get some more information such as angles and other basic proportion data? Tiffany normally provides that even on their home-grown reports, albeit in a relatively strange way (mix of % and angles).

Thanks for the advice .. I really value the input.. I’ve a thing about wanting a d coloured diamond and I think I’ll gave more peace of mind knowing I have a d rather than an f regardless of the fluorescence.. just worried about the blue hue it may take on in direct sunlight.. otherwise I’m fine with it having fluorescence

With a medium blue you are unlikely to get much of a blue tinge in sunlight. Here are some photos of a couple of strong/very strong blues.

Before you decide on D vs. F, it's easy to test your assumption out... go to any jeweller that has GIA-graded diamonds and ask them to demonstrate the difference. You may be surprised by what you (won't) see.

D does carry a premium. Especially in a luxury dealer. Whether it's justified and "visible", is a completely different question

F.

I trust Tiffany's grade on colour, and I know that I (YMMV) cannot tell the difference between a D and an F in any realistic day-to-day circumstances (set, stone not perfectly clean, on a moving hand, against a variable background, in variable lighting). So what's the point in spending for something I know I cannot see?

This said, you (your to-be-fiancée) won't wear the report; you will wear the ring, and diamonds that appear identical on paper can look quite different in reality, which is why I (YMMV again) would insist with Tiffany that they bring me both diamonds - and more - preferably set, but even in temporary settings/clips, if I really am to choose one. Tiffany is definitely better than the average retailer in terms of consistency of looks, but even their diamonds don't all look the same, and your personal preferences are yours and yours alone.

In a medium blue, no.  The fluorescence will have no visible effect.  If you are ever in a position where you are trying to resell it, the fluorescence will make life more difficult.  the F with no fluo is the easier route and once on her hand it will look just as brilliantly white as the D.  The transparency is not affected by the color at all.
