Hello,
Think I might have found "the one"

. Please share your opinions! Thanks so much for everyone''s help!

Well worth a look and consideration. Maybe some technical guy will give you some little bits on what might be different, but no one but you can decide if this one is the one you like best. It sure looks nice in terms of parameters and the IS view.
 
The IS certainly looks very nice.

photo, sorry had to knock down the resolution a bit.

What is the black spot just below the arrow at 4:00? It is visible in the IS as well as the photo? Is that something to worry about at all?

thanks everyone!
 
I think you''ll be hard pressed to see it in person. On my computer screen, the diamond is as large as the palm of my hand (if only my diamond was really that size
27.gif
), so when properly minimized in size to a more realistic size, that dot becomes even tinier/microscopic. For a peace of mind, why not ask Whiteflash?
 
It looks great to me!! The images are beautiful!
 
Any other opinions on the IS? Just comparing it with some of the other threads with IS images, the red areas are not quite as RED and there is some light leakage around the girdle, I guess. Is this worthy of concern? By the way, this diamond is $8850, I think.
 
Unfortunately, it seems that different IdealScope images taken at different times vary due to equipment set up. I have had some variation explained to me as "photos were taken with different equipment at different times". From looking at a lot of IS images on WF, I've noticed that sometimes the diamond is much larger, and at other times smaller with more white background. (Maybe that's just a difference b/w ACA and ES images, haven't tried to correlate it). If so, it makes it hard to compare intensities between images.

Perhaps John Q can address this for us? I'm a scientist in image processing and wouldn't mind the full geek treatment! Whaddya say John?
 
Also there''s the issue of whether you are comparing it to a New Line or Classic. The other thread has a New Line IS image which has fewer white patches near the girdle.
 
That is the one I was comparing to both in terms of color (ie. how red) and leakage around the edge. Thanks for the feedback on the setup differences. That hadnt occurred to me.
 
Cant go wrong with an ACA!!!!!! Ours SPARKLES and SHINES everyday for us..

I guess that is a positive vote! This is not an ACA (or even an ES for that matter). Also, I just realized that I forgot to mention earlier that this is a J colored stone. That would help in considering price/value!
 
I think it looks great! And if it is the one I found on WF''s website with those specs...then I think it is a great deal as well!

Mine had similar basic specs, and it was a bit more than that...and I love mine!

Good luck!
 
$8850 for a 1.8ct RB that scores 1 on the HCA and has those gorgeous images?!? Sounds too good to be true, but if it''s not...reserve that diamond right now, because you won''t find another deal like that again! I''m wondering why this isn''t an ES stone, because it''s really fabulous. People are actually mistaking it for an ACA - that tells you something!

One little thing - you didn''t post the clarity, so if it''s SI1 or SI2, make sure it''s eye-clean before you buy it.

Thanks Sunshine! You, in fact, are the one that had pointed out this one in my thread about the K stones. Jamie at Whiteflash has been super helpful while I have been looking so I had it sent to WF, of course.

Ahh...It''s so sad that I feel a sense of pride over this comment! Ha!

I''m glad that it turned out to look this good! Let us know what you decide!

You heard right ds, overall hue in reflector photos is influenced by ambient lighting, strength of the light source behind the stone, camera settings and the specific reflector being used. When analyzing IS photos one should look for consistency of hue throughout the diamond, not for how dark or light the overall red is. The different zooms represent changes in setup & magnification.We’re taking hundreds of photos a week and always working to evolve the process for both IS and ASET. Thanks for the geek request... We aim to please.

Cool! Mahalo.

Not that you asked ... but when I''m not on the computer reading about diamonds, I am developing algorithms for an R&D instrument that captures images of the cervix for cancer detection. They are oddly reminscent of idealscope images: small, pink, round, and a dark spot in the middle. Maintaining a uniform calibrated light source and focal distance is a HUGE deal for us. Taken up the best part of 6 months for me. We adjust exposure time but never gain. Still, hard to account for that darned variable ambient lighting. For the most part, our cancer detection algorithms work the same way as your advice for interpreting IS images:

"look for consistency of hue throughout the diamond, not for how dark or light the overall red is"

Thanks for the explanation, John. Just out of curiousity, could you offer some insight into the IS image posted above? Obviously others have chimed in with positive feedback... Seems pretty good to me but I most certainly lack the background and context to evaluate how this might compare against the superb diamonds that you carry.

Also, since you are paying attention, I just wanted to let you know that Jamie has done a superb job helping me out and that she is wonderful to work with. Thanks for your contribution to the pricescope community. I would have been utterly lost without the help of people like yourself.

thanks!

): Thanks for elaborating, that explains your interest. You know, without the medical industry we wouldn't have a lot of the tools we use in other trades. For example, the graphic in this post (used to illustrate the variables possible when image analysis or pixel counting is used for diamond light behavior) was generated via an adaptation of a sensitive medical program used to detect cancer in cells. I don't know the program but you probably do!

 
That was funny, jQ was probably typing while you were typing stook:) I am sure it was an unintentional avoidance though so I figured I would bump this and draw it too his attention:)
 
I think John and I were submitting msgs at nearly the same time... thx!
 
Thanks for the bump.

Stook1 we appreciate the kind comments about Jamie - we like her too.

I think the input you''ve received on the IS is good. If you have specific questions one of us at WF will be glad to speak with you and address them. As for PS, it''s great that we''re living at a time where this kind of interactivity is possible. Glad to be of assistance!
