    Please help me pick the better ACA

    The heart of this is the balance between weight, clarity, color, and price. Not so much cutting. G/SI1s generally cost more than otherwise similar I/VS2s. Heavier stones generally cost more than lighter ones. The reason they’re recommending the G/SI1 is that all things being equal, it’s a better ‘deal’. When you shop it, which I assume you’ve done, the dealer comes out looking better in comparison to other dealers with similar goods. The missing element is YOU. Do you prefer G to I or would you prefer something slightly bigger for less money? That’s about taste, not gemology. If you haven’t seen what real diamonds look like, go shopping. Maybe even go to Houston and look at Whiteflash. They have a showroom there. (Note: If you do this, make an appointment and let them know what you expect to see. Not all or even most stones on the website are in the store). Most jewelers don't bite and there's no obligation to buy. Tell them what you're thinking, ask to see what they have, and pay attention to what they have to say.

    Uniqueness of diamonds

    The weakness is in the value chain. The miner knows where they found each stone. Also when, what tools and techniques they were using, which workers were involved, what part of the mine and all sorts of other details. Not tracking these things would just be bad management. The same happens at the cutter. They know what they paid, where and when they bought it, who worked on it, what results they expected and how it worked out. Anything less would just be stupid. They know who they sold it to, when, and for how much. The whole supply chain looks like this. It’s not that the data isn’t there, it’s that they don’t want to pass it along for any reason short of a court order. Why not? Money. A lot of this is proprietary information, it’s extra work and extra exposure to track it, and there’s no extra money for those who do it. Customers claim they want to know, but when it comes time to pay, they’re happy enough without it. They want it if it’s free. Yeah, right. That’s why I’m suspicious of these blockchain type claims. What the blockchain adds to the program is to protect the data from tampering. That’s interesting, and possibly even useful, but it's solving a problem that no one has.

    Uniqueness of diamonds is offering exactly this service for approximately that reason. They are a large and well established company in the industry. Mine to finger provenance. It’s the underlying technology for the everledger people If you want to make even a remotely scholarly paper, make you understand the concept of ‘blood diamonds’. That’s a PR term that doesn’t mean what people tend to expect. Blockchain is designed to make it difficult to alter records. It does that quite well and it’s a darling for investors. Anything with the word ‘blockchain’ in it is a topic of discussion. That doesn’t make the underlying data valid, useful, or even true. The problem, and the solution, of so-called blood diamonds mostly has to do with do with local power in the source countries. Everledger doesn’t have anything to do with that. What they do is connect the word blockchain to diamonds, and that’s an advertising opportunity in the west. That has merit, but it doesn’t sound like what you’re looking into.

    A diamond trapped in glass

    From their advertisement: “Working with a unique hybrid form of glass that is resistant to acid, heat, and bubble formation, Diamonds in Glass® artisans use a proprietary technology to create a perfect globe housing a single magnificent diamond in virtually unbreakable glass. The special glass magnifies the brilliance, scintillation, and sparkle of the diamond so that it appears triple its dimension." This is a little heavy on the techno-babble for my taste, but there's nothing fundamentally wrong with it. I see no reason to think it's not possible with the right glass recipe and the right tools. FWIW, it does look difficult but the key is in that 'proprietary technology', i.e. the right tools. I think most GS inspections involve a laser inscription on the stone that you should be able to see through the glass under magnification. This could be done on a fake too, but as Davide points out above, it's quite a chore to fake a stone that wouldn't be all that expensive anyway. Is there some reason you're suspecting shenanigans?

    Maybe he meant that New York was too shady. Perhaps it's all the concrete. I must say, I have problems with that. I like the sun.

    Help with heart shaped ASET

    The paycheck for affiliates comes from directing you towards particular sellers. They may find the same stone, they may find one that’s better (or cheaper), or they may lead you to something else entirely. There’s nothing specifically wrong with any of that but bear in mind that we’re talking about commission sales people. Take their advice accordingly.

    Help with heart shaped ASET

    I rather like the black backgrounds but it does take a little bit of practice to interpret them. From my world (I’m an appraiser), the advantage is that you can replicate them with a mounted stone and you can’t with the white background ones. I do find them useful, just not for evaluating fire as you requested. In any case, I agree with Davide that it’s not for the same stone so it doesn’t matter a bit.

    How can i get best custom Jewelry manufacturing service in us?

    Welcome to DiamondReview. Every custom jeweler on the planet could make either of those, as I'm sure you know. Neither is especially difficult. That begs the question of what you mean by 'best', no matter how good you are. Cheapest? Fastest? Highest quality? Given that you're a jeweler, I presume the idea here is that it's you. I"ve never heard of you, which means nothing by the way, and don't even know where your store is, but it strikes me as highly unlikely that you would match most definitions of 'best'. That's not a criticism of your store, it's simply an impossible standard. What then is the point of this post? I"m going to take a guess. You're trying to promote the store. Believe it or not, I"m a big fan of that (promotion), but allow me to suggest you work a little harder at it. Sign up as a jeweler if you haven't already (it's free). Then read people's questions and provide useful and accurate answers. People will read your advice, not just the original poster, notice the link at the bottom of your page back to your store, and buy things from you. You've already established your credibility. Repeat. You'll be amazed how well it works and you'll be amazed at how much YOU learn both by knowing what people are asking and by reading the advice given by others. It WILL make you a better jeweler. By the way, read the rules. There's a link at the bottom of the page. You've already violated them by posting as a jeweler in the 'classified' section of the site. That's specifically reserved for individual sellers.

    Review of HRD 1.02ct F VVS2 3x VG

    I totally believe it's a nice stone. I'm criticizing the grading scale, not your diamond. The problem with the cut scale is this: Here's the whole scale: Excellent Very Good Good Fair Poor That makes VG look pretty good, it’s just below the best and it's usually reflected in the price, but look from the other end. Just try and find a poor, fair, or even a good. I’ll wait. Using the diamondfinder as broadly as I can, there are 524,000 round stones listed at the moment. 18,000 are Good and 1508 are Fair. None are Poor. The bottom 3 grades combined are only 3%! VG has 346,000, a little over half, but when I limit it to VG VG(or worse) symmetry and polish it drops all the way to 21,000. 94% are better on paper than that! That’s not an entirely fair test, some VG VG VGs are pretty darned good, and sometimes the issues are more subtle than those polish and symmetry grades indicate, but seeing it as almost the top is a serious misunderstanding of the scale.

    Review of HRD 1.02ct F VVS2 3x VG

    HRD is a reliable enough lab but I’m curious how you picked this particular stone. High clarity(VVS2), high color(F), low cutting (VG, VG, VG) is an unusual combination. Did you pick this or was it the dealer selling it? There are 481 superficially comparable stones in the diamondfinder database here, for example. 440 of them are graded as better cut than this one (as mentioned by Laurent above, they may have other issues that come into play but cutting seems to be your question given what you've told us about the stone.)

    I just noticed that contact information is no longer in the footers. Hmm. There seems to be no way to know who you're talking to. Davide is: Mine is

    on the hunt for the perfect emerald

    The tax benefit goes away if you report things to customs, and if you don’t report, you have the potential for other problems. It is possible, and people do it all the time, but it is illegal. Just sayin’. Davide works for a jeweler in NYC. He’s too polite to plug himself but there are links in the signature block at the bottom of every one of his posts. Who is ‘best’ will depend to a large degree on what you want. For example, I’ve linked above 399 stones that meet your requirements. There’s obviously a pricing question that’s going to come up but, in practice, most of those stones will be available at any jeweler you want. I’m not an uninvolved observer either (I’m an appraiser), but what I look for in a jeweler is pretty straightforward: 1) The truth, the whole truth and nothing but the truth. If you get a feeling that they’re hiding things or filtering details based on criteria other than yours, move on. 2) They know. There are a shocking number of uneducated jewelers out there. It continuously amazes me how many think there’s nothing important beyond what appears on the GIA reports. Not everyone knows everything and it’s fair for them to do research, but if you get a feeling that they don’t know and just don’t care, move on. By the way, don’t be shocked if they ask for a deposit. It costs money to bring in stones to show you and it takes time to talk to you. They deserve to be paid. 3) Terms and conditions vary and they get difficult in your price range. Mostly it’s not about credit cards for example. Read the T&C carefully. Plan on getting it appraised by an independent appraiser (not their guy and not a competitive seller) and you should have the right to return it if this goes badly. This often causes stress with sellers on expensive items and there is often time pressure. Compare their answers to this question. 4) You haven’t answered the questions of your objectives and what that swirl ring has to do with it, but that’s not an easy job. Not everyone is prepared to make that and not everyone will tell you if it’s outside their skill set. That may or may not matter to where you buy the diamond but that’s a complicated job. Look at their work. You’re fishing for talent over price here. 5) Search their reputations, both online and with friends. If they don’t have any footprints, move on. As you point out, there are a lot of jewelers out there. To your other question. Your cell phone (a rectangle with blunted corners) and a stop sign (an octagon) are both emerald cuts. The look is very different. Most ECs have 4 pavilion mains. That’s the A few have 5 or even 6, some have only 3. It’s not that one is better than the other, or even more expensive, it’s that they’re different. Do you have a preference? If you don’t even know the question, you’ll never know the answer, and the way you get these questions is from talking to the salespeople and by looking at stones.

    on the hunt for the perfect emerald

    It's a cool ring, but what does it have to do with the current deal? Are you looking to make a ring like that? That's not an easy job, but there are certainly jewelers who could do that. It doesn't really have much to do with the details on the center diamond in any case.

    What does Sotheby's have to do with it?

    on the hunt for the perfect emerald

    I"m going to give the same answer with a slightly different take. 2.80-3.50/D-G/IF-VS1/GIA/emerald cut has 399 offers just in the database here. Prices range from $30k-$135k. That's a factor of 4 range. 340 of them are under your budget. You need to zero in a bit, and the first step is to put some thought into how you landed on that range in the first place. In terms of pricing, your biggest issues are over/under 3.0 and if you're serious about that 'D' and/or 'IF'. Every step matters. I would abbreviate Davides list above although I fundamentally agree with it. Start by choosing a dealer, not by choosing a range of grades for the online databases. There'll be time for that later. The problem is that hardly one carries this sort of thing in stock, including the internet folks, and this becomes a special order project if you want to be even remotely picky. That makes the dealer your ally in the hunt rather than an opponent to be pitted against their competitors. There are variables that I can pretty much guarantee you haven't come across, like the number of steps on the pavilion and the shape of the corners that have a big effect on the look of the final stone. Some (like those two) aren't even mentioned on the GIA document.

    Black diamond with external inclusion

    Are you the seller here?
  17. denverappraiser

    Black diamond with external inclusion

    Note: I think the reference above about being rather expensive is to UNTREATED natural diamonds. Most fancy blacks are treated and it makes a big difference in the pricing. If you don't know, ask the seller. If you don't understand what he/she tells you, come back and ask us. I second the above suggestion. If it bugs you, send it back. It's not that hard and if your plan is to wear this daily for life, it's important that you are happy with it.

    Advise on this diamond - emerald cut

    Here's one of the dealers that advertises here who is offering that same stone without the weird data added. They may not know anything, it's obviously owned by a 3rd party, but they do have a phone number and their people are decently good at answering questions. If you have other dealers that you have a preference for, give them a call even if they don't list it. If two can get it, there's a pretty good chance that others can too.

    Advise on this diamond - emerald cut

    I agree that ASETs are useful on emerald cuts but they can be tricky to interpret. The pavilion/crown angles you've been given, on the other hand, are useless. I'll try to explain. On modern round brilliant cuts, which is where GIA provides this data, there's a set of 8 facets on the pavilion that extend all the way from the girdle to the culet. This is called the pavilion main and there's a similar set on the crown leading from the girdle to the table. The angle of these in relation to the girdle plane is what we're talking about. Even that is a problem because we're averaging 8 numbers but look at the facet pattern on yours. There is no such equivalent. There are 40 facets on the pavilion and NONE of them cover the whole range. None could reasonably be described as a main. The angles of these range over a span of at least 20 degrees. Generating a number with an accuracy in the 1/10 of a degree is ridiculous (which is why GIA doesn't do it. Notice that neither of these is on their report. They were supplied by the seller). That said, I don't have the same complaints about this stone as Davide. The lighting in those photographic systems, like the distance to the camera, can have huge effects on this sort of discussion to the point of making it useless. I"m really curious what "Table Inclusion - T2" and a few of their other statements mean. Do they give some sort of key to interpret their codes?

    Ebay engagement ring purchase opinions

    Age can’t be told from a photo either, and that general style has been around for decades. For what the the clue is worth, those egl cards are almost always done for large dealers and it’s usually done as part of the manufacturing process. They see ‘new’ things for that particular service. That one was done in 2017.

    Review of 1.60ct GIA/SI2/E round cut

    Well, the definition of I-1 includes things that affect the beauty or durability of the stone so, theoretically, no. In reality, it's more like 'it depends'. That's why SI2s are cheaper than SI1s. I've heard a rule that the prettiest flowers grow on the edge of the cliff. As Davide points out, the only real way to answer this question is by looking at it, which it sounds like you have done. Perhaps someone else can also go in with you and take a peek and, I presume, the seller has looked. FWIW, my wife's diamond is an eye clean I-1. That's the edge of the cliff. This is what's called a 'mind clean' problem. It's important, but it's not really a gemological question. If it bugs you, even in concept, move up in clarity. If you choke on the price, move down in color and/or size to compensate.

    Review of 1.60ct GIA/SI2/E round cut

    Davide. In 40 years of jewelry, I don't think I've ever seen a customer deliberately grease up a stone just to see what it looks like. It's not that this is an especially bad idea, but do make sure the salesperson is on board before doing this. Someone with heart trouble may be at risk. SI2 gets a bad rap on the Internet and I'm finding myself increasingly irritated when I hear people mention Rarecarat. It's not that they're necessarily wrong as much as these 'advisors' are commission salespeople who have NO additional information to impart. Sometimes the sellers don't either, but sometimes they do, and at least they're usually upfront about their position. You are much better off calling THEM to see if they have something to add.

    How Synthetic diamonds are made?

    The hopes and dreams of young boys and girls are collected and distilled in a secret laboratory in Russia.
  24. denverappraiser

    Review this diamond

    The secret seems to be your assumed endorsement of RareCarat and their automated pricing model. Here, for example, are a half a dozen similar offers for less, including one for what I suspect is the exact same stone. It's not much less but it nicely highlights the issue of these theoretical models. That said, the real heart of the question is what led to you that stone in the first place. Why H/VVS2? Why that particular stone? I see the photo in a ring. Is that what you're shopping for? The details of that may turn out to be more important than you're expecting.

    MY "F" color diamond was EGL and it's a GIA I Color

    I"m a big fan of independent appraisers (since I am one), but that's not really the heart of your problem at the moment. The difference between I-1/I and an otherwise similar SI-2/F is significant. More than a factor of 2. That's the issue. You will not get a GIA graded SI-2/F for the same price, even with other serious defects. Your options are going to be more money, smaller and/or lesser stone, or a refund. Remaking the ring to accommodate a different stone is going to depend on the ring design. In any case, you need to decide what you want and you need to decide fairly quickly. Some of the rules change as time passes. There's lots of EGLs and most don't have online lookups. Most are out of business. It doesn't matter. If he gave you that paper calling it SI2/F, HE is the one making that grading claim. That's good for you. Again details matter. For example, when, in the timeline of this sale, did you get that spreadsheet? Who is in possession of the stone/ring? Who sent it to GIA? When? GIA will only issue reports on stones that they physically inspect, unmounted, in either California or New York. That doesn't seem to fit the timeline above. If he can give you the GIA report number, you can look it up online. It was and still is a wonderful gift from your husband. Don't let the minutia of jewelers, labs, and appraisers spoil that. Can you put up a photo of the ring too?
