Just to let you know…. no one gives deals on diamonds. Why would he sell you a dismond for $2000. when he could sell it for $3000. They are in business to make money not make or keep friends. Also gettin a stone GIA certified in the United States is a couple hundred not thowsands.That being said if you like the stone and think you are getting a good deal I say buy it.

London_Bride:  A friend of ours bought a non-certified diamond and the jeweller told him the same as yours told you. Its about your comfort level. My husband’s take is that it was really important to him because the certified diamond came with an inscribed number etched on it. When he took it to be appraised, this etched number is something they check. To him it made him feel more comfortable that it was the diamond he paid for. Yes, you could say he might be overly cautious but when you’re talking about thousands of dollars, it was worth a little extra for his reassurance.

I’ve bought uncertified diamond, and that was a huge mistake. Instead of being H in color, it is more close to KLM – think about color of bad yellow teeth as example of the color. 

Don’t think you should play  those games when you are buying your firstdiamond and when you know nothing about how they look like..

steod:  That’s odd. Well, if you have seen the diamond and like it, it’s at a good price then you should get it. If you are planning to get it insured, the diamond has to be certified.

A few things you can do to check the diamond if you want. You can place it next to a GIA certified F diamond on a while paper and background, then you can see if there’s any difference in colour. As for clarity, look under magnefication and see if you spot anything. Go out and see it in sunlight to see how well it sparkles and if it’s milky or clear.

 

On youtube, GoodOldGold has very helpful videos, check it out and you’ll learn a few things 🙂

steod:  I have a vintage ring with a .30 center(Non-cert) The seller called the color E. To me(holding it next to other diamonds) it’s probably a closer to a G. The clarity given, VS1, seems right.(I actually have a loupe.) I’m not picky about color but I notice it. I didn’t feel cheated because the ring didn’t cost much. Under a certain price, I don’t worry about having a certificate but for anything expensive/important(the Deco ring wasn’t an engagement ring, just a gift), I’d need a GIA or AGS grading report.

I suggest one should always buy CERTIFIED DIAMONDS… It can be very tempting to buy uncertified or self-certified diamonds, because they are usually cheaper than certified diamonds. But before you grab that uncertified bargain, bear in mind you run the risk of not getting exactly what you paid for. 

Certified Diamonds will give you peace of mind that you have value for money.. instead of having lab grown diamonds I suggest have the original and certified diamond. 

 

I have IGI certified diamond.. and I happy I have genuine diamond.. so think twice before you buy uncertified diamond..

There are nuances and variables when buying an uncertified diamond. 

GIA and AGS are the foremost grading labs, and AGS grades (for cut) many types of fancy cuts, where GIA only cut grades round brilliant stones. Both of these labs have the most stringent criteria for cut, color, and clarity grades. Personally, if I’m buying a graded/certified stone, it’ll be from one of these two labs only. 

Buying an uncertified stone can be safe bet, IF you know diamonds and are very familiar with cut parameters and optics of the particular cut you want to buy. If you can read an ASET or Idealscope. If you know how to read an HCA table, or AGS cut parameter tables. If, with this knowledge, you see the stone in person under multiple lighting conditions. Lots of IFs. 

For example, older cut diamonds, including but not limited to OEC, OMC, transitional cuts, etc – the stones were around long before grading labs, and long before grading labs developed their cut grading systems. Many old stones are not certified by these labs. These labs are playing catch up, needing to come up with grading standards and metrics that apply to these types of cuts. (AGS is way ahead of GIA in terms of cut grading cuts other than round brilliant). I would buy an old cut stone that was uncertified, provided it was eye clean and from a reputable dealer of old cut, old world diamonds. 

I would not buy a stone from just any brick and mortar jewelry store (that was uncertified). I’ve seen them, I’ve owned them, and I’m not ever going to spend on them again.

zamorski :  

And just to respond to this (old) comment. A well cut, lower color diamond does not look like yellow teeth. That’s an unfortunate and incorrect statement. These are I and M color stones  

It’s not easy to tell the difference when they’re set.

Update: Wow sorry, just realized this is a 4 year old thread! I just commented since it was on the Wedding Related boards….

I personally would like a certified, and at least GIA or AGS. We put a deposit down on an EGL, then I really researched diamonds, and realized the EGL was too deep! On paper it was .97 weight but was so deep, it only face up compared to a .8. The jeweler kept telling me there’s no difference with GIA or EGL….ugh another post. We went with another local jeweler that actually carries GIA XXX+ and cuts some diamonds in house.

So if you love it, fine. But have you seen a XXX GIA in person? Very few jewelers actually carry REALLY well cut stuff. There’s a reason it’s not certified. Watch some of the videos below from Good Old Gold, lots of good education videos.

Now, if you’re not a FOMO or research type, fine, but make your decision based on all the info and seeing what potentially your options are. I suggest too if you really want the best well cut diamond, you get on Pricescope too and ask for opinions. They’ll suggest compromising on color and clarity, but never cut. Are you able to get some scans to get angles/such or you literally have no documentation?
