Comparing Two Oval Diamonds Just Over 1 Carat

Recommended Posts

My requirements:

- >1 carat

- Colorless

- VS1 or better

- Oval

- Low fluorescence

- L/W ratio above 1.35

- Table % between 53-63 (came up with these from http://www.lumeradiamonds.com/diamond-education/oval-diamond)

- Depth % between 58-62 (came up with these from http://www.lumeradiamonds.com/diamond-education/oval-diamond)

 

Diamond 1 (James Allen) - https://www.jamesallen.com/loose-diamonds/oval-cut/1.09-carat-f-color-vs1-clarity-sku-2872479

 

I liked James Allen's site features. The only thing that concerns me with this one is fluorescence.

 

Diamond 2 (B2C) - http://www.b2cjewels.com/dd/9411784/oval-diamond-F-color-VVS2-Clarity?sku=9411784&utm_source=rarecarat.com&utm_medium=referral&utm_campaign=rarecarat.com&utm_source=rarecarat&utm_medium=cpc

 

I'm not as big of a fan of B2C's site with less diamond photos than James Allen has, but this diamond fits all of my requirements and is significantly cheaper than diamond 1 at James Allen. And this diamond doesn't have the fluorescence that diamond 1 had.

 

 

Thanks in advance. Any advice is greatly appreciated.

There are a number of problems with any comparison across sites... and with any opinion based only on photos and videos (especially taken in unknown conditions), but I have to say that the B2C diamond as presented on their site is rather unattractive.

 

The JA stone seems to have a large bow-tie, but looks (with the caveats above) much nicer. Why are you concerned about fluorescence?

 

ETA: I would ignore any depth-table related rules. On any shape, but especially on something that is relatively asymmetric as an oval.

That's kind of what I felt about the B2C diamond as well, but all of the things that could be verified on the GIA report looked good so I was curious if anyone could tell me if I was missing something.

 

My only issue with fluorescence is that I've read multiple opinions of this and all things considered, would rather just remove the issue by looking at diamonds with low fluorescence.

Since you have read multiple opinions on fluorescence, maybe add one more - a serious scientific study of the effects of fluorescence on the appearance of diamonds, done by GIA exactly 20 years ago: https://www.gia.edu/gems-gemology/winter-1997-fluorescence-diamonds-moses

 

Maybe that will allay some fears.

If fluorescence bothers you, delete that stone for that reason.  As you point out, there's no particular reason to put up with it if it bugs you and it'll leaving you feeling like you got an inferior stone. 

There's a pretty good chance that JA can get most of the stones advertised on B2C (and visa versa).  Ask them.  The available pool for both companies is substantially larger than what you see on the sites.  Taking all of those pictures is a bit expensive and they may not be able to supply the images but that doesn't mean they can't supply the stone.

I have seen that before, but then others swear fluorescence plays a role. So I'm not sure how to decide between the two.

Neil is entirely right - if it bugs you, then don't consider stones with it. However, I would also add: decide who to trust, because opinions are more like eyes than noses (everybody's got at least two). Random strangers (including myself) on the internet, or one of the foremost gemmological institutions in the world?
