Wow. Amazing how lighting makes a difference. To me, the middle stone is far superior in every lighting setting, but especially in the sunlight. C looks rather sad
Basically, when purchasing, take a loupe. Check the cut and clarity. Then take it away from the stores over the top lights, and to a natural light in shade aswell as sunlight, to see colour and sparkle.Remember, if you have a low budget and choose a bigger carat, expect it to be a poorer cut , clarity and colour..and so it's sparkle won't be alot. It's best to have a smaller carat and a beautiful stone, than a lump of dullness😉
H P - Diamond B has the same round brilliant cut as the others but is the only stone that fits within the Super Ideal proportions - the measurements that let the most amount of light in with the least light leakage to create maximum fire & sparkle under all lighting conditions. Hope that helped! 😊
I learned more about diamonds in this video than I learned in the entirety of my life. Thank you so much for making this simple and easy to understand video! So great!
If the stone has either a too deep or too shallow cut, definitely affecting light return, how can it get a Triple Ex score on the GIA report? Especially on the cut grade? It seems to me that if the stone has a too shallow crown, or a too deep crown and pavilion shouldn't that exclude it from being rated as an excellent cut?
Shari D57 hi there you check your diamond on Holloway cut advisor hca tool you will get the answer your diamond score this tool will match with AGS lab. Score
I recently bought a 0.91 3x excellent diamond engagement ring (had it custom made) and was concerned that it would be too deep with a depth of 62.9%. However, once I saw it in person it took my breath away and is extremely shiny and vibrant, especially in the sunlight. Just goes to show that every stone is unique and must be considered in its own merit.
bin pham But, they are all rated “excellent” on the certificates. He says that it is a super ideal cut, so why isn’t “ideal” on the certificate? Perhaps the cut has issues in other areas that do not matter as much, but the issues bring the overall cut quality down.
Austin P you know the best way to check before by the diamond Check the Certificate and you go Holloway cut advisor hca tool tell you from 0.4 to 1.3 that super ideal cut after the that just Excellent Low The good diamond much check at Proportion
Austin P I good my diamond from ritani before I buy I check it first my diamond 0.6 score the diamond amazing event not 1 carat but too many people want to buy back from me the cut very important Sorry I don’t mean to teach you anything but I want to share my experience be for don’t know I have very bad diamond event the GIA say Excellent
@Cheryl Yoos They look pretty similar until you get to the last shot, outside in natural daylight. The middle one sparkles and flashes much more than the one on the right.
Where does it say the phrase “super ideal cut” on the GIA report? Is that the same as “excellent”? What is “triple excellent”? Does that refer to being excellent in all 3 categories?
Brilliant earth has search parameters that allow you to look for super ideal cut diamonds. James Allen has “true hearts” as their highest quality cut diamonds ...
I've found a tool called HCA where you can enter the diamond's proportions to see if the light return is great or poor: www.pricescope.com/tools/hca, just google an image of a diamond's proportions so you will know which value is which in the GIA certificate
The last diamond I sold was a GIA 0.40ct, color grade E, clarity grade IF, triple EX and none fluorescence. It was spectacular My personal opinion, for diamonds over 1.00ct, pay attention to the clarity grade (the inclusions are more noticeable) and also the color grade.
I can't tell the difference at all until the last view and that is with side by side comparison under magnification lol. Its such a minor difference that it seems pointless to me. But I guess I don't have a proper eye for these kinda finer things
Thank-you very much this I didn't know! In Italy in stores the quality is poor and the prices high. 75 percent of the stores sell only good or very good and g-h. And it is difficult to tell people it, usually I sey that their diamonds are beautiful knowing that they could have much better. Good karma to you.
Buy from bespoke/handmaker jewellers who have a degree in lapidary. Ask if they have formal training. Some of the stuff you see on etsy is really amateur, or in some cases it's just reselling wholesale jewellery or premade stuff. Put yourself back in touch with local artisans who can make you exactly what you're looking for all within the same budget OR LOWER than what you see in large corporation jewellery stores.
Metalrus you can use a Holloway cut advisor hca tool check on the certificate the diamond you want to buy the will give you answer or you check on whitflash.com AGS lab have the best diamond more better then GIA event small diamond It’s so bling
Basically the only good james allen diamonds are the true hearts diamonds. BUT many of the true hearts are not super ideal. You need to analyze the specifications and look at idealscope / ASET images to determine super ideal. James allen true hearts all have nice cut symmetry but NOT all have good optical symmetry. This all comes down to which dimensions the cutter chose. Super ideal diamonds are in a narrow range of dimensions. Whereas a bad diamond can still be very symmetrical but it'll have light leakage under the table
Haha just don't buy bad diamonds. Easily 90% of the women you see in the world have diamonds with bad cuts despite being graded very good / excellent. The range for excellent is almost half the diamonds! What you want is the top portion of excellent and they are known as super ideals and it makes a real difference. But then again we live in a world where people buy si2 5 carat diamonds just for the lollipop effect haha having no idea that they could have a hypnotic stone that is 3.5 carat and perfectly cut for same price.
What a great explanation of how three diamonds that are graded the same can perform so differently. I have been selling the super Ideal Hearts on Fire diamonds for 20 years now and I take about 30 minutes to explain what you did in 5. Thanks so much for the video.
Never buy diamonds at chain stores, employees at Zales, Jareds, Kay jewelers are people who come from McDonalds and the trash collecting companies, GO TO YOUR LOCAL JEWELER, chain stores are exploiting their employees!
Pretty rude comment and irrelevant to this article...but thanks for your bashing of all those people that work there. I've worked for all 3.. but never McDonalds or Waste Management
Hi dear so what happened if I buy the diamond certificate at GIA they reporting ideal cut so how can I check if they give the the true ideal cut or not
Need to use ASET scope to see light return pattern. First step is proper dimensions but you can only tell actual cut symmetry and performance with an aset scope. Aset scopes work for all diamond cut types not just round brilliant. Honestly it's the only way to compare diamonds objectively
Good video but I worry your test could be biasing diamond B as its always centered in front of the camera where A & C are always just off center. It's hard for me to visualize how an ideal cut should return light from an oblique angle but the charts I've looked at seem to show that the cut is designed to reflect the most light when it is coming straight into the stone (ie. perpendicular to the diamond table). What do you think? Have you seen any charts that show this?
@@SH-kh4bq not true... Andy had a good point. When differences in pavillion/crown angles off by 1 or 2 degrees can result in a difference in cut grade, not seeing diamond A and C perpendicularly matters.
Thank you for the insights ! I followed your guidance and filtered through pages of diamonds online, looking at the certificate's statistical #s, and when I narrowed my search and played the video of the one that was best, the pattern looked just like Diamond B. The others that I weeded out looked like A and C (broken arrows or grey patches). Hopefully when it comes in real life, I can see the same fire in natural lighting :D. Thank you so much.
THe ASET scope is a very useful took to analyze a diamond's brightness and fire. However, you should use it together with the proportions of the diamond (shown in the GIA report) and the Hearts & Arrows scope to analyze its symmetry. If you need any help, feel free to email us at sales@jannpaul.com We'll be happy to check it for you :)
This video shows why you need to actually see the diamond in person and compare. No online video can truly show how your diamond will sparkle. Any diamond professional will NEVER buy a diamond sight-unseen! Your local independent jewelry store is your best source for diamonds.
Dale Robertson lmao until you ask for gia very number and go look at it yourself online and appraise it for 2k cheaper than what they are asking you. Online stores offer huge discounts.
@@carlsanc3880 The online diamonds I've seen do not have the beauty or brilliance shown in the pictures or videos. Most have a grayish/cloudy look even though everything "looks" the same of the GIA diamond reports. No report states how beautiful or brilliant the diamond is. That has to be seen in person. I can find 132 offers for a 1.00 carat, round shape, H color, Vs2 clarity, Ex, Ex, Ex GIA graded diamond with prices ranging from under $4K to nearly $10K. 132 diamonds! All with "about the same grade." You can look at numbers and letters until you are blue in the face and still not have a beautiful diamond. The online store generally sell the diamonds that local independent store have rejected. They don't even have them where they can pull the diamond out of the papers and look at the diamond. It's always a picture or video, rarely in real life. Even going to the diamond centers of the world like New York or Antwerp, the real deals are not available to the public, only the trade. By going to the local independent store, you are usually dealing with the owner who stakes his reputation and livelihood on being honest and being able to help the consumer. Who are you dealing with online? I can't put a face to it.
the whole idea and tradition of a diamond seems silly to me don't take it personally, but you're one of the sheep But grandma had one and the movie star has a big one A nice piece of turquoise set in silver attracts me much more and so does the woman wearing it pay the price and get your stone
so how do you go on a research which diamond to buy? im looking at jamesallen.com and only thing i can see is GIA certificate saying triple exellent gradings and 360 degree picture of diamond which isn't really showing any kind of sparkles. Even if you go to BM shops, chances are all of their diamonds will look same, and they won't allow you to take several of them outside to look under natural sunlight. What would you do to shop for one?
Hi Straden, I would recommend to look for vendors that are able to provide you the ASET and Hearts & Arrows scope images of the diamond. This would give you a much better analysis of its light performance. Feel free to email us at sales@jannpaul.com We'll be happy to help you out :)
If they have very similar scopes but different HCA scores? Let's say 0.8 and 1.4? Which one should perform better. I'm planning to buy a diamond online
HCA is only used as a REJECTION tool. Not a selection tool. Anything below 2 can be considered but SHOULD be analysed further with ASET images and etc.
Hi Roman, It is difficult to analyze the light performance of a diamond's table size alone. It would depend on the proportions of the other angles such as the depth, crown and pavilion angle. Generally, the Ideal table size is 53-58%. However, a diamond may still have an Ideal table size, but poor light performance, depending on the its other facets. For more information about how the table size affects a diamond, you may check out, jannpaul-diamonds.blogspot.sg/2013/08/a-diamonds-table-size.html
To make the test completely fair, we would need to see each one separately, not in a row next to each other until all three had it's own time alone under each type of lighting; the reason why? Because, the diamond in the middle may have benefited from the lights cast like a spotlight from the diamonds on either side? Just to be fair & accurate.
Hi Cheryl, How you viewed the diamonds under different types of lightings can affect it visually significantly. Jewelry stores often uses callibrated LED lights, which makes everything look pretty much the same. For example, in this video, we showed how diamonds appear under jewelry store lights versus other types of lighting environments. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o9eVBFjpFVI.html Cheers, JannPaul
