I2/Fair cut/Strong blue would be described in accounting terms as an "impaired asset". In fact, it's so unlikely a combination that finding comparable prices is hard (typically diamonds of this quality would NOT have a GIA report; they would be sent to some other lab in the hope of avoiding at least one of the zingers of I2 and Fair cut).


The price by itself may even be not a bad price, IF (big if) you like the ring and the diamond and the seller provides you with some way of returning the item without penalty if you don't like it. However any judgement on this needs to be informed by seeing the stone and the ring, not photos or reports. If you are concerned, find a qualified, independent appraiser and ask them the same question.


(I would have started from something else, but I'm not you)

Thank you for your prompt reply .. I get the term right away. Well in this case, I knew I2 was almost at the bottom on the scale, I am OK with inclusions at this point in my career and would love to upgrade to a diamond of similar size with better cut and clarity. I didn't know what strong blue meant for fluorescence until I just read a report on it, I originally thought it was a positive thing but I have found out otherwise. I know it's not a great rock but I wanted a gia certification just to know it wasn't something else than what the seller was stating.. where would you start for the same price? ($1500-$2000 range?)

Thanks for your expertise. I will be receiving it today and will let you know what I thought about it in person.

Fluorescence per se is not bad; it can have undesirable effects, but it's rare. However, because of these few rare cases, fluorescent diamonds tend to get discounted, particularly in online sales, and are more difficult to sell.


The issue with I2 is that sometimes the inclusions compromise transparency and can be a danger to integrity. No way of telling without seeing the stone. Here is a "good" I2:




and here's a not-so-good one:




The issue with the "fair" cut is twofold (in this particular case):


1. An 8% girdle means the diamond faces up like a 0.80 ct, not a 0.90

2. Crown and pavilion angles indicate this is likely to be quite a dark-looking stone.


Getting a GIA report is a good plan, but what's on the report also matters...


Finally, you are getting a very elaborate setting - the design of which I don't like in the least, but that's my problem, not yours - which however has two issues in my view:


1. It seems manufactured rather cheaply (big cast sections, peg head, indifferent polish/finish)

2. The main stone is very very exposed. This may be good for showing off the stone (or not - it's an I2, and inclusions will be more visible the more the stone is exposed, even through the side), but it's a significant hazard when being worn: it will bang and snag into things, and an I2 diamond is not the best candidate to get bumped and banged.


For a budget of $2000, you can find interesting stuff on the secondhand market (e.g. on eBay), but you need to be careful. If you stick to new, I would get a much simpler (but possibly better quality) solitaire setting, and set a 0.65-0.69 H/SI1 or 0.75-0.80 I/SI2 in it. You can find them nicely cut and much cleaner-looking than an I2 for $1900 or so.

"Better choice" depends on you. It's a completely different object - other than the colour, which will look pretty similar - and it has a big chip (possibly caused when removing the stone to enable GIA to grade it - and possibly now worse after re-setting: it's right on one of the points).


Once again, I would have started from something else - but given the diversity of the two objects you are considering, I'm not sure I understand what you want other than your budget. Incidentally, I see no mention of any returns being possible on the first ring you bought, so I'm not sure that thinking about alternatives should be your first priority.
