    Engagement Ring Help Please! Marquise cut

    Hello Ellie, welcome to Diamond Review, and congratulations on your engagement! You are right that a marquise stone with those dimensions is unlikely to be 1.32 ct (unless it's very rounded, almost an oval). However, it's possible that the 1.32 ct refers to the "total carat weight" of the ring, i.e. the centre stone plus the halo stones. Without seeing any documentation , that would be my guess: a typical marquise with those dimensions would weigh about 1.15 - 1.25 ct, leaving 0.10 to 0.15 ct approximately for the halo stones. Whether that's been explained to your fiancé is a different matter entirely.

    What would you pay for this stone?

    Cut has not much to do with clarity, in the sense that you can have a poorly cut but internally flawless diamond and a very well cut but highly included one. This one doesn't score well on either count: it's a just-about-decent but not great cut and a big unknown in terms of clarity: there are I1 that are almost perfectly clear, and I1 that look like a dog's breakfast. And everything in between. At the end of the day, what matters is what you (your lady) like(s) - but I still think you need to have a comparison to a really well cut, clear diamond. Ask the vendor to provide one of like size to compare. This should be your first step: you need to understand the trade-offs you are about to make. Secondly, ask the vendor to show you the inclusions, first without a loupe or microscope and then with one if the unaided-eye viewing hasn't put you off the stone already. The objective is NOT to be put off, but to understand what's in there: what is "invisible" or "inoffensive" on day 1 often turns out to be unbearably noticeable on day 100. Thirdly, try to look at the diamond in as many lighting environments as you can: jeweller's store spotlights are great at making stones look good. Does the stone still look good under flat, diffused light (e.g. fluorescent tubes on the ceiling)? What about natural diffused light? Direct sunlight? Very dim light (e.g. under a desk)? Very yellow light (e.g. low-power incandescent lighting)? Is the stone bright, sparkly and the inclusions not highly visible in most or all of these environments? If so, you are good. The key in all of this is experience - and this only comes with repeated comparisons. At some point you may be able to do without a reference diamond that performs well, but until then, ask the vendor to help with a good comparison (by which I mean similar colour, VS clarity or higher, no fluorescence to avoid risks of haziness due to that, and a cut beyond reproach: excellent symmetry, a pavilion angle of 40.6° to 41°, a crown angle between 34° and 35° and a girdle not more than slightly thick).

    What would you pay for this stone?

    Without seeing it? Not interested. Too high a risk of an I1, strong blue fluorescence, indifferently cut diamond turning up with something "unexpected" (or all too expected, if you know what I mean). https://www.gia.edu/report-check?reportno=7306986618 If I were buying this from a reputable jeweller with a good return policy, $6,600 is not an unreasonable price for something "graded like that", but variability in what I1 look like is such that it may be a total dog or a very nice stone - and the price may therefore be a complete rip-off or a fair price. Buying from a private seller is much more of a concern and would correspondingly alter my expectations (downward!) of what a fair price is.

    Need help with diamond earrings

    Nobody does, but the problem is what "should" means. For some people, a diamond that is not totally eye- and mind-clean is not a go. For others, a cut less perfect than a perfect Hearts-and-Arrows is not adequate and so on. Your budget is perfectly sensible, especially for earring stones, but is unlikely to get you both of the above... As far as parameters go, you didn't specify clarity, but the sweet spot for your budget is VS2/SI1, so that's what I put in this search: https://www.diamondreview.com/diamonds?sortOrder=price&sortDesc=1&fShape=Rnd&fCaratLo=0.70&fCaratHi=0.75&fColorLo=H&fColorHi=I&fClarityLo=VS2&fClarityHi=SI1&fCutLo=&fCutHi=poor&fDepthLo=59.0&fDepthHi=62.0&fTableLo=53.0&fTableHi=58.0&fSymLo=ideal&fSymHi=exc&fPolLo=ideal&fPolHi=exc&fCulLo=&fCulHi=vlarge&fFlrLo=&fFlrHi=vstrong&fPriceLo=0&fPriceHi=2400&adv=1 I would recommend that you don't look at table and depth for selecting a well cut stone - crown and pavilion angles are much more important. Try to keep the pavilion angle between 40.6° and 41.0°. Finding pairs is more complicated than finding a good single stone, and this is where table percentages are useful. Start by matching diameters (within 0.05 mm is perfect; 0.1 mm is good and 0.2 mm still acceptable: there is a head in between!), then match pavilion angles and table % (within +/-2%) and you should get two stones that look fairly similar.
  5. Yep. I would say it's practically zero in ordinary circumstances. Now, if you take a hammer... That depends on your definition of "eye clean". The feather is not going to be immediately visible as a dark, highly contrasting inclusion would be, but - in the video at least (and to my eyes at least) - it interferes greatly with the transparency of the stone and it seems to make it significantly less lively. Now, all this is 1) based off a 30 seconds video, which is not conclusive proof of anything, and 2) my personal opinion only: we all have different tastes and appreciate different things even in the same object. It's all relative. I know plenty of people for whom your budget is a total dream, and pretty much anyone buying a diamond has to make trade offs on something (even if you have $100,000,000 to spend, a 10 carat natural red diamond may not be available for sale...). However there are plenty of other trade-offs that can be made, from size to colour to simply looking for another I1 with a less aesthetically bothering inclusion. Again - it's bothering to me, and that may be because I look at diamonds in a given way; there is nothing wrong with I1 per se, and I am very happy to have bought a few I1 diamonds set in pieces that my wife enjoys. Ultimately, the only valid test is for you to see the diamond in real life and preferably to compare it to a few alternatives, however disappointing the result of the comparison may end up being. Do bear in mind that as people get more familiar with objects they do see more details, and what was acceptable (or "invisible") on day 1 sticks out like a sore thumb on day 100. Which is fine, as long as James Allen is still honouring their "trade in" policy in 5-6 years time... and your other half is happy with waiting 5 years with that diamond on her finger. I don't mean to sound catastrophic, but 5 years is a pretty long time. That depends very much on the terms of the insurance policy. Most household policies are on a replacement basis: you don't get monetary compensation; the insurance company purchases a replacement item of "equivalent quality". However JA is unlikely to recognise a replacement stone as acceptable to honour their upgrade policy 100% (all possible controversies on "but ours was a much nicer stone, and worth x% more"). This is not necessarily an issue "because of the I1", since the stone really is not likely to shatter, but it is an issue in more general terms due to potential loss or theft (and "minor" damage; sometimes I see jewellery that seems to have been used to open tuna cans), if your firm plan is to upgrade at some point in the mid-term.
  6. As far as I can tell from the video the feather is nowhere near the girdle; it is parallel to the table about 1/3 of the way down the pavilion, which is about as safe as can be for setting. However, a video is NOT a good way of assessing any integrity risks; taking the stone physically to who is going to set it and asking them about that risk is a much better way to solve the issue. If that "who" is James Allen, any material risks are theirs independent of your insurance. Incidentally, the risk depends in a pretty significant way on the setting design and materials too. Insurance - why do you care? It's a problem of the insurance company, and I don't know of any that refuse cover on the basis of clarity. The fact that they are willing to insure it and usually at the same price/value ratio as a VVS tells you something about the probability of accidental fracture in everyday life (and the fact that most insurers are unwilling to insure loose stones independent of clarity tells you something about the probability of accidents happening at the point of setting - however expert/specialist insurers will insure loose stones, which also tells you something...). Feathers - even I1 and I2 feathers - are not "just a matter of time before they break". The diamond was cut with the feather in it (or the feather developed in its current state during cutting); the temperature and pressure experienced during cutting will not be equalled at any other point in the diamond's life, including the setting process, unless the diamond is re-cut. Does it make it a totally safe bet that it will never break? No, but it's very very far from a certainty. All this said - based on the video, the diamond while not disfigured has (in my view) its appearance materially - not lightly - impacted by the feather. Are you sure you want to buy it? To quote Neil, another one of the experts here, "a good price on the wrong thing is not a bargain".

    Hello, Questions about a ring

    It looks like a ring from the 1920s, but those design motifs were used also in the 1950s, and the larger diamond's cut seems quite modern; the photos are good, but there is no replacement for having the item in one hand and a loupe in the other. Value - much longer conversation. Value for whom, where, doing what? (One thing is wanting to replace or replicate it, one thing is wanting to sell it). ETA: if you need to take more photos and you want to use pliers to hold the ring, put a couple of rounds of decorators tape (or duct tape) around the pliers' jaws; it will prevent scratching!

    Diamond ring for sale

    @denverappraiserNeil - I think one of the links you pasted was a "clipboard leftover" from some other thread... @slickamannI think this is what Neil intended to post: https://www.diamondreview.com/forum/forum/5-jewelry-classifieds/ To your second question, other than agreeing with what Neil has written, I can only add that the buying price is not useful to determine how much it could sell for; a more precise description of the object may at least help us help you with some very rough steering, though (as explained in Neil's write-up) to get a reliable assessment you need someone to actually look at the thing (and you need that someone to be an expert working for you).
  9. @AnnaSmith You may have more luck in getting responses if you start your own thread, rather than resurrecting something that is 7 years old... That aside, yes, jewellery made with precious materials is expensive, but there is no scarcity of things made with cheaper materials; silver and bronze can look very nice, and even gold in small quantity is not all that expensive. CZ is cheap if you want the "diamond look" without the cost (and syntehtic corundum is also cheap if you want ruby or sapphire), but there are plenty of lovely natural stones that don't cost an arm and a leg: all quartzes, tourmaline, garnet and even spinel and sapphire can be affordable. I'm not sure that this helps with your question though: at the end of the day, you are the one wearing it, choose what you like.

    @Furqan Shafi I think Bogeywon is asking whether he should stay away from it, not saying he should. @bogeywon There is no compelling reason for you to stay away from Costco, and they do have great prices and fairly described merchandise. However before you pull the trigger consider the following: 1. Limited choice: that particular set of rings comes with that one stone. If the stone is poorly cut (and we have no indication either way), you can't change it. Make sure you take a good look at it before buying; I suspect the image is a CAD rendering, not a photo, and you should try to compare it to what else is on offer on the market; simply looking at the information on a report, especially for a highly variable shape like a cushion, doesn't even begin to tell you whether the stone is nice or not. 2. No qualified support/advice either at the moment of purchase (e.g. advice on cut, showing you comparable stones or tweaks on design) or - as far as I know - afterwards: if you lose one of the pavé diamonds, you need to find a jeweller to replace it. Costco cannot help other than by taking the ring back (but see the next point). 3. If you modify the ring(s) in any way, including sizing (and Costco will not size them for you) they are not returnable. This can be very expensive; Costco say (honestly) that the design is sizeable within one size, but sizing those rings requires some skill. If someone gets it wrong, you may be stuck with needing a rebuilt ring at your expense. So, while shopping at Costco on some things may be a slam dunk, on expensive jewellery I'd be more cautious.

    Don't know if you want to spend 20 bucks, but these (or similar) may be worth it if you are going to break the parcel up https://www.amazon.com/dp/B07D4F9BRG/ref=sspa_dk_detail_0?psc=1&pd_rd_i=B07D4F9BRG&pd_rd_w=bOoxU&pf_rd_p=f0dedbe2-13c8-4136-a746-4398ed93cf0f&pd_rd_wg=cuavc&pf_rd_r=9VT09F8RXNZJ0FYFXST3&pd_rd_r=5c58d60c-266c-11e9-8d89-2156212e8c69

    Loose diamonds value and usage ?

    Hello Marc, welcome to Diamond Review! Small diamonds are difficult to resell; they can be used in making jewellery, but whether that's "value" to you is a different question. Part of the problem is that diameter is only a small part of what determines value - the fact that they came from a high value estate (or even a high value piece of jewellery) means very little; colour, clarity and cut quality are by far more important, and we (you?) know nothing about it. Just to clarify: 1. The fact that there were several important pieces in a collection does not mean that all the pieces are of excellent quality 2. There are many important pieces of jewellery that have what would be considered poor quality stones. Leaving aside all sorts of non-gemmological considerations as to why two 3 mm diamonds may be priced differently on eBay, a factor of 3-4 is possible due to colour, clarity and cut grading.

    Thinking of selling the diamonds I bought

    It's a tough one. Melée is difficult to resell at the best of times. Where are you based? Putting "Makis" into Google Maps comes up with sushi restaurants.

    The Perfect 3 Carat Hunt

    As long as the two images were taken by the same people using the same techniques... the second is better than the first (which I would say is much closer to an "average" excellent than a dreadful one, BTW). Be careful if you are comparing across vendors - not everyone is skilled at taking these images, and not everyone does it the same way.
