Opinions on pear ASET, please!

[sharona]

Longtime PS lurker, first-time poster. Been in love with the gorgeous pears of FireGoddess, cflutist and DiamondLil fame so much that I''m going with that for an engagement ring. Just starting the process but this one caught my eye.

Any opinions on this ASET? (Expert and regular-joe welcome)

I''ve read the tutorials on ASETs but just wanting to put it out there. Thanks!

Isn't there suppose to be 3 colors, not just 2?
Wouldn't this indicate no light return from a certain range of angles?

And isn't there supposed to be a nice mix and even distribution of the colors instead of blotches of one color here and there, etc.?

Another poor black background ASET sigh. Sigh it looks out of focus.

Cushion, should the background be a different color? Most of the ASETs I''ve seen posted have been on black backgrounds.

Also, kenny, from what I''ve read here, fancies don''t perform nearly as well on ASETs and people have even commented on how ASETs of pears sometimes don''t show blue, which confuses me because isn''t that where a bowtie should be?

Anyone else? Thanks!

Hi Sharona

Can you post the actual photograph of the diamond please? And the depth, table, crown height if you have it and diameter etc. I take it the diamond is GIA graded? Also you have excellent taste in pears by admiring the beautiful diamonds of FG, cflutist and DL.

Concerning the bow tie you will need to ask one of the vendor's gemologists to evaluate it for you, images can be deceptive and aren't the best method of judging them.

lorelei, just got it sent to me not long ago. It''s the one on the left (I like ''em fat). The one on the right was too "ice princess" for me. I don''t think it was taken in the best environment. I called about the darker triangularish spot toward the tip and the gemologist said it was just in the photo. When she moved it around, it was active.

Thoughts on light leakage, performance, bowtie? Thanks!

Are you sure the ASET isn't for the diamond on the right Sharona? It could be the angle of the diamond of course in the photo and I could be completely wrong but it looks to me as if the ASET belongs with the other diamond.

With the diamond on the left, can't really judge light leakage or performance from a photo but it looks like a pretty pear from what I can tell. Also can't really judge a bow tie from a photo, it looks as if it might be prominent but really best to ask someone who can see the diamond, bow ties can be deceptive and show to a greater or lesser extent depending on the angle of the diamond one is viewing it and the lighting.

ETA - I see the ASET for the other diamond has just been posted, wouldn't hurt to double check the original image is for the first diamond, just looks as if the shapes are a bit different to me but it could be the angle of the pear in the photo as I said earlier. Which vendor has these for sale?

 

[sharona]

Here''s the other ASET for comparison, lorelei. This is for the pointier pear which is on the right in the photo.

Also, I''ve read a lot of your PS posts too

I''m liking the pear on the right better (is it just me?). Maybe you should ask for more photos of the one on
the left? Anyway this vendor can do a video of the stone?

 

[sharona]

Not sure about the crown height but:
Depth: 66.0%
Table: 59.0%

I know it''s deep, but the fat stone seems more lively than the skinny one that tyty prefers. Also, dunno about providing a video. These were the only two ASETs I requested, so I''m guessing they match correctly. The angle at which the photo was taken is odd, I must agree.

Its difficult to tell from those ASETS, which vendor has them Sharona? What I would do is to ask for a face up closer photo of the fat pear, the angle is odd and I can''t see what I want to from that shot unfortunately. Could you ask the vendor if they could run a Sarin scan for this pear and maybe get an Idealscope image of it too?

 

[sharona]

Also, a little confusion. My boyfriend and I have both been working with the vendor on this, and the BF let me know that the ASETs were taken a couple of weeks ago. Apparently the camera was still being calibrated, the vendor tells me.

Just a clarification.

There are two types of ASET images once which is backlit and the other which is not. I prefer the backlit one with a white background as you can focus the image better and see leakage better.

The problem with these images is both pears have significant leakage (which is normal in Average and Above Average Pears) so the colors are being blended with black and it makes it difficult to see zones of leakage and the contrast is difficult to make out.

The ASETs are not mixed up they correspond correctly to the two diamonds, you can tell by the shape and the contrast patterns as compared to the photographs.

Also you don't need blue for a bowtie although blue is a stronger indication of one. From the photograph neither seem to have a significant bowtie but both have some dark areas at the thickest part of the stone where you would commonly find a bowtie. However, both have a lot of leakage and not a lot of RED in the ASET meaning they will perform well in strong spot lighting but not as well in darker conditions.

I'd be concerned about how well the fatter one performs at the bottom of the stone, looks like a lot of leakage and not much direct return(Red in ASET) I would ask the Gemologist about that and you might consider comparing these to other stones you might find.

I can't see the photo to compare it to the ASET image clearly enough to determine this, can you explain what you are seeing please?

Lorelei,

1) Look at the ASETs one is clearly fatter than the other. If you must measure the LW ratio of both I can see it by eye.
2) Look down the axis of the fatter looking stone in the photograph towards the bottom there is an unmistakeable obtuse triangle on the lengwise axis which ends near the bottom of the stone and is an area of great leakage (black area). This same black area shows in the ASET of the fatter stone and its shape pattern is much different from the other stone.
3) It has already been established that these ASETs were taken 2 weeks ago when JA's ASET camera was still miscalibrated, if this has now been fixed the OP should request a new set of images.

I just want to clarify this sharona, is the vendor James Allen and did they take the photographs of both for comparison?
