    Please Help Diamond Comparison

    It helps a bit, but all we are confirming (or not, as the case may be) is whether the prices are reasonable; the 1.80 being retailed by a high street store may be OK. For the other two, it depends on what you mean with a "private diamond seller"? A private individual (i.e. a consumer) that is reselling a diamond they bought from a retailer some time ago? If that's the case, the prices are very high. Unfortunately, it still says nothing with respect to the appearance of the diamonds, and this is usually what people buy diamonds for. I have added the link to the third stone's report to my post above, in case anyone wants to comment. Having looked again at the three reports, I have to say that the 1.80 doesn't look like a great stone on paper; it's smaller face-up than both the 1.70s and it is very possibly not eye-clean (like the 1.70 G; best chances on the 1.70 F - but I may be totally wrong on all three). It may still look very lively, and better than the other two; however the reports don't tell us - on a blind bet, I'd bet against it.

    Hi there, The 3 stones are all sold through different types of retailers. 1.8 Ct is sold through a store in downtown LA Both the 1.7 are sold through a private diamond seller. Not sure if that info helps or not. Let me also re type the GIA for that stone you said did not work. GIA-2337712640

    We (you) have a number of problems with the information available: 1. SI2 clarity diamonds vary enormously in the extent to which their inclusions are visible to the naked eye. There is no way of telling with certainty what is the case from the report alone. FWIW, assuming the three stones are being retailed through the same type of retailer (internet or high-street, chain or single store, ...), the fact that a higher colour, larger stone is cheaper than the rest is NOT a good sign, unless you don't mind having visible inclusions. 2. There is virtually no information about cut. Ovals are not graded for cut by GIA, and the only reliable way of understanding whether a stone is well cut or not is to see it - ideally in comparison to the others. Good quality photos (including reflector images if well taken and you know how to read them) are an OK substitute; video - especially if comparing two or more diamonds together - is even better. The prices you are being asked are higher than average for internet-based retailers; they may well be reasonable for a high street store, but then a bricks-and-mortar retailer should be able to organise a viewing so you can choose the one you like most (or ask them to procure alternatives). Finally, the report number for the 1.70 F/SI2 is either typed wrongly or there is an issue with the report.

    Hi, I am currently in the process of buying an engangement ring and need to move a bit quick here. I am so new to diamonds and do not know much so looking for professional unbiased help. Can I get as many responses as possible to which stone I should choose. This will be for an oval shaped diamond on a 14 ct yellow gold solitaire ring. 1.8 Ct Oval Color E Si2 Gia- 6315797095 --- $12,275 1.7 Ct Oval Color F Si2 Gia- 2337712649 ----$12,900 1.7 CT Oval Color G Si2 Gia- 1318764593 --- $12,500 Please help any let me know what im missing with each diamond.

    Is this the perfect one?

    None of the diamonds discussed in this thread have any fluorescence. One of the vendors used a blue reflector to do their imaging. If that is what you are referring to with your nonsensical statement, then you may want to revisit what you said.

    WTF? 🤪

    Is this the perfect one?

    I think this is Blue Fluorescence diamond. This is such a very precious Diamond you can buy it without any tension. If you don’t have much money to spend and want to buy a diamond in the I-K color range, you might consider buying a diamond with medium or strong blue fluorescence since they are usually sold at a discounted price. Though please be aware that I do not recommend buying diamonds with fluorescence apart from diamonds in this particular color range or If you actually like you can buy it.
  10. The Diamond Finder would be my first port of call to see what's there. While what you are looking for is not super-rare, there aren't thousands of 3 carat ovals sitting on the shelves...
  11. Again thank you, David! All very helpful - my gut feeling says I can do better and unfortunately the search continues, although I'm sorta running out of time as I was planning on proposing in 3-4 weeks on a trip. Do you have any recommended websites/vendors that I can continue the search online? I've looked at a few local jewelers (I'm based in San Francisco) and big brand companies such: Blue Nile & Brillant Earth and did a quick search on the diamond finder on this forum.
  12. You are most welcome, Diego! Yep. I've seen the video - same one as the one on the B2C site, meaning neither vendor owns the stone, and both are brokering (which is perfectly normal). As I mention above, those proportions on the Yadav site look like "left behind" from a round brilliant. Possibly a scripting bug, a copy/paste error in their database or good old-fashioned deception. GIA does not measure those proportions on non-round brilliants, much less does it issue a cut grade (and much much less uses the term "ideal" for anything), so it may be interesting to know where they got them. Even if they have actually measured them, I'm not aware of any published studies on the influence of pavilion and crown angles on appearance in ovals, so what's the point? All of this helps in possibly identifying better vendors; unfortunately not to figure out whether this is a good stone. My gut feeling says you could probably do better - though much depends on what you want to prioritise. ETA - it may seem I'm pushing B2C. I'm not - they are a much more significant competitor for me than either of the other two discussed in this thread!
  13. Hi David, really helpful. THANK YOU. I've been talking to Yadav and they provide the following specifications on the website, they also have a video as well. I can ask about the 8 pavilions and 8 crown angles. Although B2C is significantly cheaper at $30,894. - https://www.yadavjewelry.com/diamond/oval-diamond-2.99-carat-h-vvs1-yd8142213
  14. The "other vendor" (B2C) has more info as well; their site is now back up so I'm posting the link. https://www.b2cjewels.com/dd/12694811/oval-diamond-H-color-VVS1-Clarity?sku=12694811&utm_source=diamondreview.com&utm_medium=referral&utm_campaign=diamondreview.com the ASET image is either very poor or very poorly taken. The video shows a fairly flat and lifeless stone - though it seems to be without a bow-tie. It could well be the video rather than the stone. You have added some proportion data; these look as if they have been taken from a round brilliant, not an oval (where amongst other things it makes no sense to speak of a single crown or pavilion angle, since by definition there are at least 2 of each, assuming perfect symmetry). If these have been supplied by the vendor, ask them how they got them and why they are not releasing the complete scan data with all 8 pavilion and 8 crown angles - any uncertainty or obfuscation there means they made them up.

  16. The honest feedback is that there isn't that much feedback that can be given. There are two potential areas of concern: 1. The cut quality. We know zippo about it. One static photo is not enough to assess anything, and the report is no use (there is no cut grade from GIA 2. The fluorescence. We know GIA assessed it as "strong blue"; the main risk is that the stone turns hazy/smoky/milky/oily in UV-rich light (i.e. sunlight), but the single photo posted has been taken in a light box with virtually no UV in the environment. The same stone appears to be on sale through other vendors for a similar (slightly lower) price, but all that this confirms is that the price is reasonable; it says nothing about whether it is the right stone for you. FWIW, 2.7 to 3.1 makes a heck of a difference - not only are you looking at a 13% difference in weight (which is $4-5k on the total give or take), but you are crossing a significant threshold at 3.00 carats, which will increase the price/carat.
  17. I would suggest you use the diamond finder on this forum and set criteria between 3.00 and 3.50, FGH color, IF - VS2 clarity, None to Medium fluorescence. Sort by price low to high, and start looking at pictures and see which one you like best in your budget. And select that.

The biggest factor I'm scared about is the fluorescence being Strong and clearly it being a bad diamond for my future wife and spending this type of money.

    Excellent summary by Davide. I’d you want to dig into it, I would start with the annual reports on the diamond industry by Bain & co. as he linked. They’re all free and available. They aren’t exactly beach reads but they’re content rich. My only caution as you read those is that they’re talking about rough stones only. They report on the mining business from the perspective of where’re or not you should be investing in the mining companies. Jewelry is related but bit different. It’s a complicated soup.

    Need help! Which of these are the best?

    It depends on what you prioritise. You have chosen three fairly different stones for your shortlist, ranging from 1.21 to 0.90 ct, D to H in colour and SI1 to VVS2 in clarity. Not to mention three very different sets of proportions for cut, and a price range for the stones of well over 12% (considering the prices include the same setting!). FWIW, in terms of cut proportions I'd rank them 1.02, 1.21 and 0.90 - none of them are a truly excellent cut from my point of view, in as much as it can be assessed from a GIA report. The 0.90 is the weakest proposition of the lot, unless 1) price is a strong consideration and 2) the 1.02 and the 1.21 are not eye-clean (which is a possibility for both). The choice between 1.21 and 1.02 depends on eye-cleanness of both stones, and once that is cleared on whether you privilege size vs. colour (though colour may not be that visible from the top and once set) AND on what set of proportions you prefer. The 1.21 is likely to be brighter but with less fire than the 1.02 Prices - it is a guessing game, because a "custom platinum ring" could be fairly worth $500 or $3000...

    I'm not @denverappraiser, but the straight answer to your first question is "no". Not because there is some great secret about diamond prices (if anything there is more data than you want - much of it contradictory), but because the question truly has no answer. You may have seen graphs like this one: (source: https://www.wsj.com/articles/SB10001424052748704337004575059723597630174) followed by something like this: (source: https://www.leibish.com/how-color-diamonds-have-appreciated-over-the-years-article-624) followed by something like this: Source: https://fortune.com/2017/08/29/gold-and-diamond-prices-charts/ So doesn't this answer the question? At least, doesn't it answer as far back as 43 years ago? (I can also tell you that in the 1970s prices of diamonds grew fairly constantly in both real and nominal terms, not least thanks to high inflation and the creation of a speculative bubble that exploded in the last months of 1979/early 1980 - you can see the peak in the first graph.) No, in my opinion it doesn't: 1. These are "asking", (supposedly) trade prices; not what the diamonds actually sold for. Discounts (or premiums) were not consistent over time and over categories (see 3. and 4. below) 2. Retail prices have had a different evolution - broadly following the pattern, but with a more consistent drop over the last 20-25 years as competition in diamond retailing (internet) has eroded margins very significantly. 3. Depending on what particular diamond size, shape, colour, clarity and cut quality you look at, you may have very different results. Marquises were very fashionable and highly prized in the 1980s; now they are as dead as a dodo, but worth about as much as a dead common pigeon - whether wholesale or retail. Pink diamonds were a relatively cheap collector's curiosity in 1980; now they are hugely expensive. 4. Standards have changed - especially over cut for rounds (and less so for other shapes). Something that was a very commercially viable diamond from the 1980s or 1990s would struggle to be sold at a discount today, and something bought as a super-premium cut in the early 2000s would not go for as much of a premium now. 5. In recent years (last 5-10? Too close to call), the overall jewellery market has changed size and shape; occasional jewellery has become much more popular and diamond jewellery far less aspirational in developed countries, yet demand for diamonds has continued to increase because developing countries are catching up (pace the last graph above). The overall impact on prices is hard to determine, and may be more variable (relatively) by geography than it used to be. (6. Not a factor that determined historical prices, but a significant influence in the future is the presence of gem synthetics. This is still minor nowadays (at least overtly) - but it will shape prices much more significantly in the coming years, and it is something that was conspicuously absent until the mid 1990s.) So, if you want a meaningless average, you could argue that roughly the real price of diamonds has remained about constant over the last 50 years, it has declined strongly over the last 40 (because of a timing fluke), and it has decreased a little over the last 30. Yet there are people who bought a diamond 50 years ago and are sitting on a huge loss, and there are those that have bought one 40 years ago and could make a nice amount of money on it - for different reasons. Wanting to make an analogy, it's a bit like asking "what has the price of cars done over the last x years". On the one hand, on average, it has certainly declined relative to average earnings; on the other, luxury car prices have increased more than earnings and some of the most expensive cars ever are on the market today, and on a third hand (Larry Niven and Jerry Pournelle anyone?) the price of a 50 (or 60) year old car is even more variable than that of a new one. All "true" to some extent; a lot depends on the time horizon one is looking at. At the moment, there is relative oversupply, which is why prices are soft, and that is expected to continue for the next 2-3 years, but not beyond that. Population keeps growing, and even though demand from India and China (and other developing economies) has not grown to the extent expected 10 years ago, it has grown and it is continuing to grow. There are diamond mines that are running out (e.g. Argyle in Australia - one of the reason pink diamond prices have increased as much as they have), and there are mines recently opened and being prospected in Russia, Canada and Central Africa. If you want a lot more data and information you could do worse than reading through some of the "Diamond Industry Reports" published by Bain & Co. between 2011 and 2019. Just bear in mind when you are reading that they are being sponsored by the Antwerp Diamond Council... https://www.bain.com/insights/global-diamond-industry-report-2019/

    Diamond Appreciation

    Denverappraiser, I enjoyed your analysis and reading your posts. Can you answer one question straight up? Over all on average, wholesale and retail, how much has the value of diamonds increased in the past 30 years? 40,50 years? I heard recently heard a story on Bloomberg there was an over supply of diamonds that was expected to last for some time, contrary to many articles published on the web I've seen about how scarce diamonds are supposed to become in the future because of the so-called "limited" resource available. I've heard some new mines were discovered in recent years. Can you shed some light on this also? Thank you for your time. Sincerely, John D - S Florida

    Hi Andreas, you are most welcome! I think that 0.733 is particularly well cut - so double congratulations on finding a nice stone and an even nicer person to give it to. Best wishes for the New Year!

    Hi Davide, this is real help what you do ! Thanks for taking the time to write all this that detailed to me ! I have chosen the 0.733 ct. There was the hope that.... bigger etc, but I also compared the 0.1mm difference and draw that on a paper and, as you said, was hard to see the difference. I was then blended by the bits of more ct, the color and clarity even I've read this before online that it is not that visible for the eye. You brought be back in the right position. Thank you for being part to find a great gift for an incredibly great and loving person. THANK YOU Andreas

    Your Diamond expertise

    There are two "problems" with this: 1. Cutting a diamond with high(er) precision and (more) exacting symmetry costs time and money. You largely get what you pay for, especially at these price levels - the difference between WF and JA here is a few hundred dollars, the rest being like-for-like. 2. Especially with princess cuts, there is no authoritative cut grade established* which means the only way of figuring out whether a stone is well cut or not is to see it. Not all stones have video and/or reflector images, and comparing across those that do is difficult because they have been taken in different ways. There may well be stones which are as well cut as those at Whiteflash (or Brian Gavin, or Cut By Infinity, or...) which are a little cheaper, but finding them takes time and effort. (* The AGS cut grade system is authoritative and technically excellent (in my opinion), but there are so few AGS-graded stones out there, and the majority of these from a premium cut vendor anyway, that it is almost pointless to search for them outside those vendors' inventories.) From that point of view, by the way, it's worth remembering that James Allen (and many others - I'm not calling out JA specifically on this) calls the cut of their non-rounds "ideal", but they don't have (or at least don't publish) a good standard of reference for doing so. They like the cut, and call it ideal; don't like it and call it excellent. Someone else may have a different idea of what a well cut stone looks like, and I definitely have a different idea of what a cut grade looks like! I think bringing more stones into the mix is only going to add to your confusion; you need to sort out if the just-below-5 mm size of a 0.75 - 0.80 well cut stone is enough for you, or if you definitely need higher. Second, look at your budget and decide if you can go higher and if so by how much; with diamonds there's always going to be one that's just a little bit better and a little bit more expensive. Third, if budget and size - assuming a really nice cut - don't fit, consider lowering clarity or colour: most SI1 will be eye-clean in the size you are looking at, and most H or even I stones will look white; clearly if you bring clarity down but colour and size up... price may well stay where it was or even increase (e.g. the 0.834). FWIW, although the 0.834 is going to be visibly larger, I prefer the cut of the 0.733; if size is such a huge problem, a well built halo will make the centre stone look much bigger and it will cost less. I can't get to any of the JA stones by copy-pasting the links (there is some weird formatting added by whatever you are using, and I don't have the time to strip it out), but I doubt any are as well cut as the Whiteflash stones; JA has a premium collection for those ("True Hearts"), and even the True Hearts are not as finely detailed in my view. I'm about to go out for the rest of the day; I will respond to any further posts when I return late this afternoon (CET).
