I believe everything can be measured or quantified, even a diamond's light performance. By just looking at its bling under various lighting conditions, one is only QUALITATIVELY evaluating its light performance. This is very subjective, some might find it extremely sparkly, while some might find it dull.

So how to QUANTITATIVELY evaluate the light performance of a diamond? Well, nothing beats the ASET scope! It is a widely used and accepted tool to "measure" a diamond's light return. ASET plots for good and bad diamonds are readily accessible for everyone as a guide -- more red areas means good light return and less light leakage. This has been scientifically proven and remains one of the most trustable way of QUANTIFYING a diamond's performance.

The HCA is also another tool, but its usage is limited only to rejecting bad performing stones.

I understand now... that's why I am apologizing to all JP fans and employees here... Only diamonds from JP is good. All other companies are providing crappy diamonds, even though the ASET may look deep red.

Only buy from JP, my best recommendation to all.

Hope no more critizing my purchase liaoz

My criteria for a diamond is simple, below market price and can bling until my eyes pain, and I got what I wanted.

My standard for a diamond is too low and only JP's standard is the best. When you have found JP, you need not seek further because they are the best the diamond industry has ever seen.

I think you should stop... You're sounding more and more like from Luzure.
If you're happy with your purchase so be it. If you're not from Luzure, you're giving Mr Daniel a bad name instead.

Right, I am a scientific person and I totally agree that most things can be quantified, in this case using the ASET scope.

Showing again the ASET for the diamond that my cousin got last year:-

Can you show me your diamond ASET indicating better light return please? I would like to consider this when buying a diamond in the future.

Disclaimer:
Newbie here, I attended JP diamond education and didn't read up much beyond the JP lesson I was given.

Your ASET image looks good but if the price is extremely cheap for a big carat then I think it must be "flawed" in other areas. No not sour grape but i believe you get what you paid for.

http://jannpaul-diamonds-paul.blogspot.sg/2012/07/diamond-buying-aset-or-hca.html

Do you have the gia cert? Measurements maybe to calculate the HCA score ? The ideal scope image?

JP diamonds all have nice aset/ideal/H&A scope image and a decent HCA score. If your cousins diamond have all the above image to prove then I think you really got a great deal.

I have my own scope images from JP but I don't think it is necessary to post it.

Lol. Ok lets leave specific brands out of our discussion to avoid people being butthurt.

The key issue here regarding your purchase is the seller's claim of 'exceptional light return', which was obviously not the case when you posted the ASET scope images.

So from a pure technical point of view, your diamond cannot be truly certified or called 'exceptional light return' when the ASET scope clearly shows it is not.

The HCA score is 0.8, within TIC range.

The Ideal-Scope just shows the diamond as very red... nothing special to see... See the ASET better right?

But I know even though no flaw can be found, there must still be some "unknown" / "ghostly" flaws, that's why we could get the diamond at such a good price.

As some people in this discussion suggested, only JP sells the perfect diamond, all other diamonds are crappy and all other jewellry shops are selling crap diamonds.

I think most people here can agree that visually - there is no flaw. Your diamond can be super bling but that is highly dependent on light environment.

If you view it in the day with the bright sun as your source of light, of course it will sparkle as - like any other diamond will.
Needless to say, in a jewelry shop with all that LED shining around - even the worst cut diamond will sparkle too.

So yes. The ASET scope is really the true determinant of light performance which in your case , is poor. I can bet if taken at normal room lighting, your diamond will be dull compared to a better cut diamond with better ASET scope images.

And why you edited your post to shoot other people and JP again??? :s22:

Look carefully, there's flaws in the ASET you posted. I'm lazy to point out but it's not perfect. Why are you thinking that everyone are against other Jewellers. People are just stating the facts on the genuine honest and trustworthy dealers where they properly classify their diamonds professionally, which its obvious that luzure are not.

Iirc the diamond was a J color and with strong florescence which would at least in part explain the low price. No idea what the "market price" for such diamonds are cos I've never been quoted for a similar one in the several jewellers I visited

My two cents terms such as exceptional light return is objective and not subjective.

The reason why jp is recommended again and again is because they have consistently been able to provide diamonds that conform to the currently accepted specifications of an outstanding diamond.

Just curious, why do you have to keep emphasing on sparkle until eye pain? The word 'very' should do the job.

Also can somebody volunteer their rock of similar size, colour, clarity, asset image to be compared side by side with his cousin's under normal lighting condition? So we can verify his claim and if possible prove his innocence?

I'm just trying to support the JP fans and employees here so that they don't continue attacking me again...
The diamond I got, JP may sell the same spec but perfect in all other ways for more than 10k, outside normal jewelry shop quoted me 7k plus, online shop also quoted 7k plus, and I got it for 5.9k from a diamond trading company (I guess they are not considered a jewellery shop).

Even though there is no table leakage or facet leakage for this diamond and the ASET is so deep red, and that the real thing looked so fiery until our eyes pain, I'm sure soneone here can show me a better performing ASET in terms of light return.

Hard not to get attacked right? Because I should have gotten the diamond from JP instead. I regret now and if time can turn back, I'll get from JP.

I know my mistake now, just stop criticising my purchase please.

Do you take us as fools? You think no one can tell your posts and comments on JP are sarcastic?

From your pov, ppl here are JP fans and employees. You tried and got shot down.

There are opportunities for you to rest it. A logical move will be to get out of this thread. You went on to challenge people and came up with sarcastic comments.

Why are you trying so hard?

Curious. Very curious.

Errr, i don't think we are criticising your purchase, but rather the way you replied here. If you think your diamond is a worthy buy, why are you saying that if you can turn back time, you will buy from JP instead?

Doesn't make sense when this is just an online forum VS the thousands of dollars u claimed that you saved.

I looked at the few aset pictures I got from jp and found the middle to be all red. Has anyone seen in person one that is green too? Kind of curious if the difference is noticeable.

Personally don't know how to see the flaw in his aset image except that it's not as symmetrical as mine..color wise looks ok.

Hca score is great but can you tell us the gia cert number? For me i really curious to know if it's a really great diamond at damn affordable price. Thus will need info on carat, inclusion, fluorescent, got ideal scope image? Got hearts and arrow image?

Currently all we know is the aset and the supposedly 0.8 hca score.

My own diamond is 0.43 so can't really compare with your.bigger carat.

Ok heres mine. Not same size but I dont think size matters here in when comparing ASET:

Now compare against yours / or your cousins' that you posted :

Yours has more white meaning more leakages.

The dot in the middle is also referred to as the table reflection. Because in the end the dot is just the reflection of the table facet by the pavilion angles. Now, depending on the exact pavilion angle the area is either receiving light from above 45° or below 45°. And this means that the centre will either be green or red.

Scientists from AGS have found out that when the pavilion angle is above 40.768° it will receive the red light from above 45°. When the pavilion angle is below 40.768° it will receive green light from the below 45° spectrum. Obviously there is also a twilight zone in which the centre can be somewhere in between red and green.

As a perfect pavilion angle can range anywhere between 40.6° and 41.0° the centre of a super ideal cut diamond in an ASET image can be either green or red. So don’t get intimidated by that!

Come on lar, Mr Khong. No one is criticising your "purchase". We are only pointing out the flaws in your ASET image and the fact that Luzure claiming it to be of "exceptional light return" is very misleading.
