    Diamond Appreciation

    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.

    Are GSI reputable and reliable certifications?

    $10k is on the high end but a far bigger issue is the grading accuracy. The difference between a GIA 1.25/I/SI2 and an otherwise similar 1.25/J/I1 is nearly a factor of 2 no matter where you buy it. It's even more if we include things like cutting and fluorescence. These are not tiny details.
  3. They do have different packaging for different items and some things come with a drawstring bag instead of a box. One thing about Tiffany is that they're supportive of their clients. Even clients who buy what is, for them, inexpensive goods. Call them up and ask. They're sensitive about the boxes because they don't want to fuel the market for knockoffs by supplying genuine boxes but if they owe you a box, they'll produce one.

    Are GSI reputable and reliable certifications?

    No matter who graded the stone, if you’re worried about the reliability of the grading, have it checked out by your own expert. Where are you and I’ll try and send you a referral? Most are not expensive and there is far more important information than appears on the lab documents. Remember, it's not a second opinion if it comes from the same source as the first. To answer your question. GSI is a large operation that provides sales documents to a wide range of dealers. They’re popular with the chain and department stores. Do with that information as you wish. You’re right to be nervous about claimed discounts as well as the grading details. Those are among the questions to ask in the above appraisal session with YOUR expert.

    Get a thermal diamond tester. Ebay has them cheaply. I wouldn’t get the kit from idealscope. The $25 one is just fine for what you’re doing unless it’s intended to be part of the sales presentation. As a warning on sales presentations, it’s unlikely that what you buy will be very impressive under an IS unless you get into the recutting business. That’s an entirely different can of worms. Most of what’s out there is pretty bad in terms of cutting, and most sellers don’t want to highlight that. The only problem with the $25 one is that the lens is made of plastic, so you need to be careful not to damage it as you schlep it around. There are better sources for tweezers and the like. $125 won’t get you a single color master, much less a set. The one you linked to is CZ, which is not the same thing. As mentioned previously, this is the #1 stickler for people getting into this business. CZs are trouble. Theoretically, synthetics would be ok but in practice I've never seen a set. Those are nice enough lamps, but I’ll warn you they’re a little bit fragile if you’re going to be on the road with it. Again, consider your purpose. The sales presentation is different than buying. Ott makes a lot of choices that are popular. By the way, the lamp is for color grading, not brightness/fire/scintillation. If you’re traveling, lack of standardized lighting at client sites is a HUGE problem. Buy a better loupe. 10x Hastings triplet. I use a Nikon but there are others as well. I”ve had the same loupe for decades. Schneider is well regarded. Expect to spend over $100, not $12. Look to Kassoy, not ebay. While we're at it, cheap tweezers suck. If you are doing work at a client site, bringing in a microscope mostly isn’t a choice. They’re too cumbersome to travel with, Certainly not a good one. A decent scope will be expensive. My primary one is made by Wild Heerbrugg but you have to do a retrofit to get a darkfield. GIA Instruments sells them. Meiji Techno is popular. Don’t skimp here. If you really get into the grading business, this will become your #1 go-to tool. $1500 probably isn’t enough. Get a camera with a good lens and practice with it. You'll find it more useful for sales than you ever imagined.

    Inclusions in bought diamond

    I understand. 'Eye visible' is not the standard for clarity grading because it depends so much on your vision, the lighting, what the viewer knows to look for and similar non-gemological properties. Most 0.31 SI2's for most viewers under most viewing conditions are eye-clean. I realize that that's a lot of weasel words but the answer to your question is to look at the stone, not to rely on the grading report. A photo doesn't help. If you've got a return policy and enough time to deal with it, your risk is low. Get it, look at it, and proceed accordingly. You may consider using the help of an independent appraiser with an experienced eye and a standardized lighting environment if it worries you.

    Why are you second-guessing this? What has you worried?

    How to get traffic and sales?

    For example, here's a thousand competitors, all of which are cheaper than you and most of which are paying for their placement ahead of you.

    How to get traffic and sales?

    Advertising costs money. Often quite a bit. Big-time online dealers like James Allen and Blue Nile have 6 digit budgets for this. Sometimes you can pay on the back-end, like etsy or ebay, where you're paying a commission on sales, but fundamentally, if you want to be an online store you're going to have to break out the credit card. Even then, it's a bit tricky to decide WHO to pay. Google and facebook good places to start but it's not the end. If it makes you feel any better, 250 hits in a month is pretty good for a brand new site without any marketing effort. Posts like the above will do nothing for you other than, perhaps, result in some good advice (for free!!).

    By the way, as much as I'm a fan of GIA education for the right circumstances, I'm not yet convinced your situation applies. It's about like learning to ride a bike by reading a book. Practice and good feedback are keys. You do need to practice the right things but it's on you, not so much the school.

    You’ll need a Leveridge gauge or equivalent. Personally I like presidium equipment but there are lots of choices. Get a good scale. Uv light. Thermal tester. The tool that usually chokes beginning buyers is a set of diamond color masters (not cz’s). A good microscope should be high on your list. A good camera (not just a cell phone). Tweezers, trays, and assorted things like that. You'll need good data sources and good contacts for sales. Are you expecting to set up an office where people bring things to you for sale or are going to be a traveling ’picker’ buying from places like pawn shops where you go to them (and take your equipment with you)?

    Hi Thomas, I use a Sarine diascan and am very happy with it. OGI out of Israel is their biggest competitor for this sort of equipment. They're a little cheaper and also very popular. Honestly, most people do it with a loupe and some practice. That said.... Are you serious? The most important thing is skill on the part of the operator, not the tools. I definitely would not call a screener for type IIA diamonds the first and most important first step but the Gemlogis isn't a bad tool. I would call the most important some education, a loupe and a lamp. If you're trying to train yourself, reflectors like Idealscopes or ASETs are pretty helpful and less than 1% of the price of the Sarine thing. Do you plan on buying inventory based on your own grading talents backed with your own money? What do you plan to DO with this inventory after you get it? Retail them? Sell them to the trade? That's the hard part. You're probably going to have to GIA them anyway. If you want to be a jeweler, and I do think it can be a pretty good gig for the right person, I think you're focusing on the wrong area. Selling is way harder than buying, and people who are good at the selling part usually find that sources aren't that hard to find.

    Thanks for the plug. As Davide mentioned, appraisals are mostly local affairs. Some good places to look for referrals are: If you can tell us where you are, I"ll be happy to try and give a local appraiser. There are a lot of TLAs out there (three-letter acronyms) and I'm hesitant to make any sort of comment based on that alone, but I will say that although it's popular in the corporate sphere, most retailers don't use them. No, there's nothing specifically wrong, it's just unusual. Is this a store somewhere? You say you bought a diamond from them. Can you tell us more? Is this the brand name on some sort of certificate or the name of the store (or both)?

    Ask ’em. Often it's a matter of supply. In the internet databases, the seller usually isn't the owner, and the owner is who sets the prices. They can ASK whatever they want.

    The HCA doesn't really apply here. In both cases, you've got better information in the form of the AGS cut grade. You can't grade color from a photograph, especially a photo you didn't take and don't even know who did. Color grades are tiny steps and the variations in photo procedures account for far more. Frankly, I'd go with neither and find a 1.50+. It's not that hard, it's not that much more money, and if it bugs you now, it'll bug you more later. If you need to bring the budget down, compromise a little bit on clarity.
