    Natural Or Lab-Grown? Pls Help To Choose

    With even more respect... but are you connected to either Tiffany or the other store? If you are a genuine consumer, I think the community here would be delighted to hear about your experience at either place, posted in the appropriate forum, in your own thread and not as a response to a 4 year-old thread that the OP has not been following since October 2016. Posting links like this runs the risk of not being taken seriously, or even moderated.

    Help??! Downgraded Diamond

    Um, with all due respect - this is a nearly 4 years old thread... BTW - welcome to Diamond Review!

    My new engagement ring :)

    Yes, it was a link to a retailer's home page. When her (?) text implied it would be a personal photo. If the site weren't getting this sort of spam more regularly, I'd be more inclined to believe in an error - but from a one-time poster that doesn't even come back... it's pretty definitive proof.

    FS: Double Diamond Eternity band

    To save any readers time in converting: UK N - O = US size 7 - 7½; 54 - 55.5 mm circumference Best of luck with the sale; it's a very nice design!

    Which one should I pick?

    Well, rule of thumb says +10% per colour grade G-J, +10% per clarity grade within VS: G to I is +2 colour grades, VS2 to VS1 is -1 colour grade, which gives (more or less) a + 10% on grading. Add on another 10% as a premium for "Black" and the price is quite internally consistent. It doesn't help much with the decision, but at least it can be explained. 😉

    Which one should I pick?

    Hi Zoe, welcome to Diamond Review! I'm not sure I can be of much help - both diamonds are very nice, and you are aware of the trade off with the colour; any cut differences are so minute that they will be completely invisible once the stone is set. Ultimately, I think, it comes down to what you would do with the "saved" USD 730 (and any taxes on top) otherwise, and this is not something anyone else can know or tell you.

    Welcome to Diamond Review, Renato! Please take a minute to read the forum rules https://www.diamondreview.com/misc/forumrules especially re: self-advertising. The link used to be on every page, but it got lost in a software upgrade... sorry!

    ASET Images - Which image looks like the better stone?

    I would not be concerned about the blue; the stone does not seem to be overly dark at any point, and contrast is required to make the stone look nice and sparkly. On the other hand, it also has a fairly flat crown, which is not to my personal taste... Once again - you have seen this. If you like it, then it's right.

    ASET Images - Which image looks like the better stone?

    Assuming they are representative of what the stones look like (i.e. they have been taken competently and in a very similar way), the first one looks much better (alternating "cornices" of contrast and direct brightness) for my taste. The second one is not bad, but it's likely to be less bright and contrasted and possibly with a bit of windowing (see-through - which will look dark once the stone is set and on a finger). All of this said, if you have seen them and you like one better than the other, go with that rather than any ASET!

    AIG labs trustworty? anyone has experience?

    Well... couple of observations: 1. The vast majority of diamonds are sold with no lab report at all. At best a description from the seller which may or may not contain any details beyond weight, and if it contains anything else it may or may not be accurate. 2. The three vendors you have linked have in total ~130 items for sale (some of which are not accompanied by a lab report). But let's assume they all are, and all the reports are AIG. There's another 2,800 auctions for diamond ("diamant") on Catawiki. Let's say that 90% of these are "AIG" - total "AIG stones" advertised: 2,650. The three retailers have a total of 1,150 reviews - or ~10 for each advertised piece. Multiply that total by 10, and we arrive at 26,500 "AIG" stones ever marketed via Catawiki. Here is the link to the round diamonds advertised by half a dozen diamond retailers on this website: https://www.diamondreview.com/diamonds?sortOrder=price&sortDesc=1&fShape=Rnd&fCaratLo=0.01&fCaratHi=200.00&fColorLo=D&fColorHi=Z&fClarityLo=FL&fClarityHi=I3&fCutLo=&fCutHi=poor&fDepthLo=0.0&fDepthHi=100.0&fTableLo=0.0&fTableHi=100.0&fSymLo=&fSymHi=poor&fPolLo=&fPolHi=poor&fCulLo=&fCulHi=vlarge&fFlrLo=&fFlrHi=vstrong&fPriceLo=0&fPriceHi=1000000000&adv=1 There's 409,000 round diamonds advertised; plus another ~160,000 in shapes that are not round; I'll use "round only" in the next paragraphs. Some diamonds are advertised by more than one retailer, so let's take away 10% of the count for duplication. Total "unique" stones advertised: 368,000. Of which 98% have a GIA or AGS report; that's 360,000 stones. There are more out there... and these are the ones for sale, not the ones sold. Some of the advertisers here, like Blue Nile, have sold literally millions of diamonds over the last 20 years, most of them with a GIA report. Note that the largest lab in terms of volume of reports is probably IGI, and - because of the market that these advertisers cover - IGI stones are a small minority of those advertised here. Might is not equal to right - the only point I'm trying to make is that your sample is a bit biased and AIG is a relative minnow compared to GIA, IGI and HRD (which are the truly "big guys" in diamond gem labs). For whatever reason, some people on Catawiki sell AIG diamonds; whether that's because the buyers don't know, don't care, or trust the sellers, I have no idea. But given the relative volumes, it's not particularly surprising that there isn't that much feedback on AIG. All this said, totally agree that the more info there is out there, the better!

    AIG labs trustworty? anyone has experience?

    Hi Olivier, welcome to Diamond Review! A couple of old threads mentioning AIG... https://www.diamondreview.com/forum/topic/4577-first-time-robbins-bros-aig-cert-scary/?tab=comments#comment-18786 https://www.diamondreview.com/forum/topic/11287-some-diamonds-expert-please-help-me-thank-you/?tab=comments#comment-60473 where you will see that the opinion is basically as follows (and I hope that Neil @denverappraiser will forgive me if I borrow from him): 1. Anyone can set up a gem lab. No qualifications or expertise are required. 2. This means that the default answer to "can I trust this lab?" is no - they need to earn your trust either via their reputation or your direct experience with them. 3. AIG is not well known, and I assume you have not dealt with them. Be careful! Bear in mind that the report that a diamond is marketed with is not a random choice by the seller; it is a very definite marketing tactic.

    Should I be concerned

    The potential replacement seems to have two broken points - unless it's just the photos. May be worth asking before you start the exchange.

    Should I be concerned

    That is a huge knot - the whole crystal twinning is visible. And you have another significant feather located towards the sharpest tip of the kite (left in your picture - the feather seems to go nearly across the whole tip), which frankly would worry me more than the first one... On the other hand, this has been cut and polished, so setting should be a walk in the park - until it isn't. Unfortunately, the only sensible advice is the one you have given yourself: go and see the setter (not just the jeweller - unless the jeweller is also going to set the stone). FWIW, it is a very cool stone (in my opinion), but not one that I would like to set in a ring - not just for the risk of breakage. The one that is already set (last photo) seems to have a much better polish. When you are looking at exchanging, are the possible "exchangees" something that you have already seen? I don't think there are that many diamond kites flying around...

    Narrowed My Search to 4 Diamonds - Thoughts Appreciated

    Significantly more useful than a diamond in most circumstances. And it carries you, rather than the other way around.

    Question regarding clarity on a lab-grown diamond

    Hi @madisonsmith, welcome to DiamondReview! I hope you don't mind a question: what is your relationship with the site you linked in your post? Do you work there?
