    Inclusions below the center

    The answer to the second question is: if it is visible under 10x magnification through the table ("top") of the diamond, then it will be considered in the clarity grade; how "deep" (near the culet) the inclusion is, is irrelevant. Whether it affects the grade is a different matter: the grade may be determined by another characteristic (e.g. a small cloud near the culet in a diamond that has a big feather across the crown). The short answer to the first question is no. A big, black crystal right next to the culet will look rather horrible, and a thick cloud in the same place may make a diamond look dull. The key here is to bear in mind that (at least in theory) inclusions graded "below" I1 (on the GIA scale) should not have any material effect on transparency and brilliance; in practice some SI2 with a lot of diffused clouds or twinning wisps may be rather hazy and dull. And some SI1 (and rare VS2) highly contrasting inclusions will not look particularly nice to the naked eye - even though transparency and brilliance will be unaffected.

    Clarity grade is not based on light return. It's based on what's visible to the diamond grader under 10x magnification. So yes it may or may not have an impact on the clarity grade but that will be independent of light return. Also GIA does not grade any diamond for light return and nor does HRD or IGI (the other 2 most popular labs globally). HRD sometimes however does leave a transparency comment but that's not the light return you're talking about.

    Inclusions below the center

    Hello, As far as I understand, in a brilliant cut diamond, inclusions below a certain height point won't have any effect of the "amount and quality" of returned light (when viewed from the top). Is this correct ? If so, will it have any effect on the clarity rating of the diamond ?

    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.

    Natural Or Lab-Grown? Pls Help To Choose

    What does your girlfriend think? Does she want a ring with an original diamond or an artificial one? My girlfriend is also environmentally friendly and I support her in this, but when I gave her an engagement ring with a real diamond, she didn't tell me anything and was very happy with the ring. I understand it is easier to relate to this topic. And who wouldn't like engagement and engagement rings like https://www.tiffany.com/engagement/shop/engagement-rings/ or https://www.gsdiamonds.com.au/engagement-rings/

    Help??! Downgraded Diamond

    This is a very strange situation, without insurance it is better not to buy an engagement ring. I know that there are stores where it is possible to return the ring. The quality is not inferior to other jewelry stores. I tried to take a chance and order wedding rings in one of these stores, but I didn't have to return them

    My new engagement ring :)

    Why do you think she had a spam link? Was it a link to the store where she ordered the engagement ring?

    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 Den, thank you for your suggestion. yes I think I may ask them to see what their opinion is. As we don't get to see the difference between these 2 stones through our computer screen. So his advice or at least his consultants can be helpful in this case Yes both are nice and that makes me confused with the price range. As I don't mind the extra bucks being spent on the Black diamond if it performs superior to the other one. But I would also want to ensure it's smartly spent. Thank you for your prompt response and advice

    Ask Brian or his peeps? They do have a pony in this race so you need to take their advice with a grain of salt, but they're a pretty straightforward company. They might just give you good advice. Be fast, by the way, these things don't tend to stick around long.

    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.

    Which one should I pick?

    Hi everyone, Here come the diamond I have selected that after narrowing down the price and specs. Initially, I intended to purchase the Black by Brian Gavin 0.711 carat - G color - VS-2 diamond. However, yesterday I discovered this Brian Gavin Hearts and Arrows 0.711 carat - I color - VS-1 clarity which technically saves me $700. When putting these two stones side by side I couldn’t even tell the differences between them. The ASET images, sizes, inclusions are pretty much similar. Although one is G in colour and the other one is I in colour, there shouldn’t be much difference unless it is put side by side. Especially when the ring chosen material is rose gold, I’m not too particular on the warmth from the I colour. Now I’m so torn between these two for which one is a better option and worth the money spent. Could anyone please help me and shed some light on these two stones? Thank you.

    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.
  25. Should I be concerned about that much blue (compared the amount of red) in the ASET? This is a link to the stone itself. Thanks https://www.rarecarat.com/product/76463051
  26. Thanks David! I concur with your thoughts. That's the behavior I saw in the each of the stones themselves.

    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!
  28. Trying to make a final buying decision on a 3.01 G Asscher stone. I've seen both stones in person and under diffused and spotlighting. I have both ASET images. Looking for advice on the science of which of the two attached ASET images would give the best light return and have the least amount of leakage? I think I have a good sense of the answer, but looking for professional advice! Thanks Bill

    AIG labs trustworty? anyone has experience?

    There's a large company called "American International Gemologists" that produces sales documents for jewelers, mostly online, with the masthead AIG. They make them by the thousands. Your headline and URL is for "Antwerp International Gemological Laboratories". These are not the same. The heart of your question is simple enough. A seller produces a report from AIG that says something. Should you believe it? Maybe. Maybe not. The merits, or lack thereof, of AIG is on them, not the seller and not us. The fact that the seller chose them tells you that it's their guys, not yours. The fact that it includes at least some information that you know to be false is a bad sign. The fact that you are having a hard time researching them is a bad sign. I took the opportunity to look up a more-or-less random offering on that site. Like the ones you're looking at, it's being sold by an Israeli dealer. Several things came up in a brief look. They supply a clarity grade of 'transparent' on the ruby. That's not even one of their choices on the clarity scale they include right next to it. They missed some critical information, notably treatments or lack thereof on the ruby. That's a huge deal in the ruby business and it's the #1 reason people would want to see a lab inspection report. They don't even say if it's natural or synthetic. They give it a cut grade, which has no scale at all. The jewelry has an 'excellent ideal finish'. I can't even take a guess what that means and, again, no scale or context is given. Does that make them wrong or unreliable? Absolutely not, but I'm not sure what you would rely on them for. Then there are those reviews. 138 of them. I didn't read them all but it seems to be full of comments on how happy people are with the shipping speed. That's a fine thing, but it has nothing to do with the reliability of the paperwork provided. I didn't spot a single one that talks about the subject at hand here. Maybe I just missed it. https://www.catawiki.nl/l/39719003-lilo-diamonds-aig-certificate-14-karaat-geel-goud-ring-1-26-ct-robijn-diamant-0-42-d-f-vvs
