OK, so, it looks like I might finally be in a position to get a decent diamond pendant. I want a halo pendant, with a centre stone of around 0.40ct. I don’t want much bigger, as I prefer a ‘daintier’ look; equally, I don’t want much smaller.
SOOO, I need some serious help choosing a stone! Colour-wise, I’m colour sensitive, but, for a necklace that I can’t see (ie it’s not the same as a ring which is very visible to the wearer), I’m OK with H. Clarity-wise, provided it’s eye-clean I’m cool. Cut has to be excellent, no compromises. Then I get stuck: I have no idea about polish/symmetry; is excellent a must? Also, I’m confused about flourescence…
Atm, the main contenders are:
0.38 triple x H VS2 (GIA) ($1050)
0.39 triple x G VS1 (GIA) ($1100)
0.40 triple x H SI1 (GIA) ($1000)
0.51 triple x H SI2 (GIA) ($900)

@barbie86: You’ll need to provide more information for us, specifically the crown/pavillion angles, and depth and table % from the GIA report (the diamond diagram near the bottom of the report). The GIA Excellent cut grade is quite broad, and those angles matter in finding which one is best.
Have you seen the SI1 and SI2 in person to see whether it’s actually eye clean? If not, ask the vendor at what distance the inclusions are visible, if any. Vendors can have different definitions of ‘eye clean’. They could define it as looking from 10 inches from the top, while your definition could be from 6 inches from all sides. You shouldn’t have any clarity issues in the VS range.
Excellent polish and symmetry isn’t absolutely necessary, but nice to have. I personally wouldn’t go below very good though.
Flourescence is generally viewed as a bad thing by many jewelers, since in rare cases strong flourescence can make the diamond appear milky/oily. This is in very rare cases however, a GIA study concluded that 0.2% of flourescent diamonds have this negative effect. This has the benefit of making the price cheaper. Fluorescence can help a diamond appear whiter in lighting with UV in it, like direct sunlight (it doesn’t have any effect in other types of lighting).
I suggest taking a visit to Pricescope, and creating a thread asking this question. Those people are diamond enthusiasts/experts, and can really help you find the best stone for your budget.

@plantobee: Thank you so much for your reply.
I’m not a massive enthusiast in that all I want is a nice, sparkly stone, within my budget, and not to get ripped off in the process lol.
The more detailed specs are:
0.38 H VS2: 59. depth 59.8%; table 61%; no flouresence.
0.39 G VS1. Depth 60.4%; table 59%; medium floursence.
0.40 H SI1: depth 63.1%; table 55%; medium floursence.
0.51 H SI2 (NB: need to see it before I can decide if I’m happy with it, but, I think for a pendant, I’ll be OK with it even if it has small visible inclusions): depth 62.06%; table 55%; no flourescence.
As I said: because I’m wearing it as a pendant and not looking at it all the time I’m not overly fussed on the specs; I just want a good-quality stone that will sparkle nicely. I just have NO idea what I’m doing: I only know about the 4Cs, when it gets beyond that, I’m clueless.. :-s

PS. I haven’t seen the SIs, but, it’s a local-ish company, so, I can view them. They also have an excellent reputation so I can order and then return. So, that isn’t a massive issue.

@barbie86: Do you have the crown and pavilion angles as well?
Once you have those angles, use the HCA calculator to get a score. You’re looking for less than 2.0. They are all GIA excellents, so whatever you choose won’t be a dud, but there are better and worse ones. The HCA is a rejection tool to help weed them out.
It’s up to you how much research you want to do, or how fussy you want to be. I’ve seen people walk into a store for the first time, and within 15 minutes buy an e-ring, while I take the complete opposite approach and spend forever making a decision.
There’s only so much anyone online can tell you about the stone (at least without getting things like ASET images). You didn’t mention the prices, so I can’t comment on whether you’re getting ripped off. If there’s a way to view all of the stones side by side in the store in various lighting environments, I’d highly recommend doing that.
