David in this case the stone had been painted quite a bit. In slightly steep deep stones that makes quite a difference.Date: 7/2/2009 7:01:35 PM

HI everyone!
I don''t know if TripleC is even still looking on...
The conversation certainly has taken a life of it''s own...
If she has been following and still wants guidance, is it safe to say that in this case, she should trust her eyes?
We can''t really ''recommend'' any diamond we haven''t personally seen- but based on the ASET/IS and TripleC''s real life impressions, wouldn''t it be safe to say she should go with her eyes in this case?

I agree with stone-cold about the leakage in the IS for the E. However, maybe in real life the leakage is not apparent. Make sure to compare the stones under a table, away from direct light to see if the E goes 'dark.' The other thing I'm wondering -- and others who know more about this than I do, please chime in -- is that maybe what appeals to you about the E is that you like the combination of the long lower girdles (80%) and the E color. I had a stone with similar specs (a D with 81% lower girdle facets) and it was indeed white and sparkly. That may be the visual quality of the stone that is appealing to you, and there's nothing wrong with that - colorless stones with long lower girdles have a definite zip to them, IMHO. I'd say double-check one more time in a dimly light part of the store to compare the two stones, and if the E still looks good to you, go with that one.
Then SaraPJ's observation makes perfect sense.

Wow, if this is true, then I have just learnt something major! I always believed that the IS images were to do with sparkle. However maybe light leakage and sparkle are two different things. In which case....what do we have to measure sparkle????Date: 7/2/2009 2:13:58 PM

I don''t believe the IS images will tell you anything about sparkle. For that you will have to rely on your eyes.

Hi Sergey
No you didn''t miss anything, I posted the link as Sharon mentioned Idealscope images , as that page explains the normal use of IS and ASET and that IS is not used to measure sparkle.
Thank you Garry.Date: 7/3/2009 3:30:55 AM

If you count them in a round along side a princess, the princess will have more sparkles. But the ones from the round are probably bigger and brighter. Ideal-scope / ASET show the potential for light to be returned (or not).

It's suspicious how the OP posted, 'So what you're saying is, I shouldn't trust my eye? '
That is just TOO short, sweet and perfect if the OP really was a newbie here.

RG, there is a large difference between someone who doesn''t know anything about diamonds looking at them in trick lighting and someone who gets some education and looks at them under a variety of lighting.
I have no problem with someone making an informed decision by eye after careful evaluation.
For example when I did my i1 test I used scopes and angles to make sure I was comparing apples to apples.
Then I did a critical evaluation and reach a conclusion.
As far as reflector images go there is a lot of information in them that is well beyond comparing the images to a chart if someone knows what to look at.
Reflector images are just one part of the puzzle.
There is also a huge disconnect in many parts of the trade in how they look at diamonds compared to how consumers look at diamonds once they buy them.
I would add to this the use of the IS and the ASET. You need to educate your eyes to know and discriminate among diamonds. This is an invaluable service that PS provides, along with our experts and prosumers. I remember a walk down 47th St. I was like a babe in the woods. I knew nothingDate: 7/2/2009 1:02:31 PM

The point of the HCA can be to help train your eyes so that you know you can trust them. Without some training, the eyes are not the best disciminator. It takes a little effort to learn what to look for and what to see.

Many vendors sell poorly-cut diamonds that hold too much weight to have good light performance.
They can make more money selling a steep deep 1 carat than the well-cut 0.8 carat that would have resulted from the same rough.
How can they get away with this?
Because most of the public is ignorant. ('She just wants a 1-carat because her sister got a 3/4 carat.')
Weight is EASY to understand.
Cut is HARD to understand, at least it was before we got the HCA, IS and ASET.
These tools expose this industry scandal of forcing higher-profit and poorly-cut goods onto us.
Customers using these tools and educating their eyes is a threat to the status quo.
This must make these vendors unhappy.
The party's over.
I don't blame them for trying to fight back by saying things like, 'Respect diversity of opinions', 'Trust a vendor who has worked in the industry for many years', 'Ignore this new technology and buy the cuts that the industry insiders have preferred for years', and 'Trust your eyes'.
Readers here see right through this.
What they are really saying is keep your eyes ignorant because I'm loosing sales.
Educated consumers don't want the diamonds they sell.
It's suspicious how the OP posted, 'So what you're saying is, I shouldn't trust my eye? '
That is just TOO short, sweet and perfect if the OP really was a newbie here.
Make no mistake. There is a war going on here and a lot of money is at stake.

Serg I just pulled the 0.8 ct number out the the air.
Sorry, I shouldn't do that.
I should have said lower weight, but the main point of my post remains.
Vendors who do not sell well-cut diamonds will work to discredit IS, HCA and ASET tools.
They will encourage customers to 'trust their eyes' even if their eyes have not been trained or ever seen a well-cut diamond.
When cut education improves market demand for well-cut diamonds will grow and cutters will cut that way.
PS is all about cut education and pulling us into the future.
But watch out for old-school vendors here trying to keep us in the past.

I really feel that this is the big aprt of diamond knowledge that many people do not take into account when they provide the advice to "trust your eyes". Virgin eyes see things differently that eyes that have been around the block and loved a few different diamondsDate: 7/2/2009 9:18:30 PM

Well, thanks, Stone-cold; but I must say, everything I learned about lgf''s came from Storm and his research and comments on the PS forum. And I also learned by direct observation, i.e., living with a stone that had a 34.5 crown angle, a 41.0 pavilion angle, and 81% lgf. It was stunning, and there was no light leakage. It had a definite personality and it was very sparkly -- a little lower on contrast and fire than I liked, but very high on scintillation and white sparkle.

Sarapj- its not magic, nor does it need to be rocket science.
From the sound of what you wrote, you have lived with one diamond, therefore you''ve made decisions about diamonds in general.
To really learn about the cut of diamonds it''s necessary to physically examine many of them. Any learning done solely in a book, or over the web without hands on experience has limited value.
Rockdiamond, you''re right, I am not a diamond seller; I am a consumer. However, I am also 50 years old, and I''ve seen a lot of diamonds in my years, in stores and on my friends'' and families'' fingers. I think consumer experience is valid because as Storm mentioned a few posts ago, most diamond sellers don''t live with the diamonds in the same conditions that the consumer does -- i.e., day to day wear in a variety of conditions.
My first diamond (from my first marriage in the 1980s) was a 60/60 -- a very popular cut at that time in the pre-hearts-and-arrows era. It was a very "spready" diamond that looked at least 15% bigger than its actual weight. It was also a very glassy looking diamond and it looked rather gray in many lighting conditions. The clarity was above average and the color was a G or an H. That''s all the information we got back then. It came with an appraisal but no certification. The appraisal was done in-house by the store; it was not an independent appraisal. A pretty common diamond transaction for those days; my friends all had similar stones. I sold the ring after my divorce and used the money to start a travel fund for my first trip to Europe.
I decided I didn''t like diamonds -- my own and others I''d seen looked gray to me and dull, unless the ring was in a brightly lit restaurant or jewelry store lighting. During college, I worked many retail sales jobs, and I knew the mark-up on jewelry was approximately 200 to 300%, and I thought buying jewelry was a big rip-off. Instead, I bought a lot of vintage and estate jewelry, simply because I liked it and the prices were better.
I thought of diamonds'' beauty as kind of a myth after my own experience. When I got married a second time, I chose an emerald cut sapphire, and was thinking about getting it reset for my anniversary when I stumbled on this site, and my attitude toward diamonds and diamond shopping changed forever. Instead of being at the whim of shopkeepers with limited selection and lots of merchandise to move, I found I could educate myself, and that my education gave me some real choice (and power) in the marketplace.
I would not have purchased a diamond without the cut education provided here. Quite simply, I don''t trust merchants to do this for me; I do it for myself. My husband and I also subscribe to Consumer Reports and we research everything we buy. This doesn''t make me qualified to cut my own diamond, nor does it make me qualified to assemble my own washer and dryer, but it does help me balance how the product is likely to perform in reality (i.e., my day-to-day life) with the salesmen''s "puffery" and biases about a particular product.
For my anniversary ring, I looked at dozens of B&M stores and felt like I was being "charmed" and "sold" in every single one of them. I worked with several online vendors and never once felt like I was being talked down to and never once felt like they had something to hide. I ended up ordering two ideal cut stones from two different vendors. I kept one and sent one back. They were both gorgeous. I used my cut education and the HCA, IS, ASET technology to select the stones, and I used my eyes to select the one I preferred visually.
But I was choosing between two well-cut stones, not a selection of who-knows-what presented to me by a vendor with limited inventory, bright lighting, and an agenda.
Why do I spend so much time on this forum, laboriously typing in responses like this, when I could be outside enjoying the beautiful summer weather -- it''s simple -- it''s because I was a newbie here just a few short months ago, and I was confused and feeling vulnerable and not knowing who to trust. I read a lot of posts on this forum and besides the cut education, the posts I found to be most valuable were from consumers just like me who were being guided through the process by the pro-sumers and experts on this board. For too long, the diamond industry has been controlled by very few voices, I am so glad to see this is changing and that there is a consumer advocacy site like PS!
