What does this Pear shaped Aset Image mean

[sparkles]

Anybody please.

Is it a good light returner please.

Here is the IS image of the same stone

It looks leaky and uninspiring to my untrained eyes. I've seen better ones.

Interpreting Images
Blue areas are the dark contrast areas you observe in a diamond due to obscuration. In the ASET configuration it is intended to represent light coming from 75 degrees to 90 degrees. The amount and distribution of these areas are important. In the AGS metric well made round brilliants have about 18% blue content. A princess cut runs less than this.

Red is the most desirable color to have in the image. This is intended to be light coming from 45 to 75 degrees: It is not obscured so it is producing brightness via the most direct light.

Green light comes from the horizon to 45 degrees. It is usually reflected light and of lower quality. It should be minimized if possible with this important exclusion: Undesirable in large quantities, green is not altogether bad depending on the size and distribution of the areas in the image. It is one of two vehicles whereby brightness contrast effects are produced - the other is leakage.

Black (or white if using white backlighting) represents areas of non-reflection referred to as leakage. Depending on how you define it, this is ‘escape’ (a better scientific word than leakage) or simply non-returning facets.

sparkles, I''m far from an expert, but I think it looks pretty good.

Gary provided this link in another thread about a pear IS and ASET, and said although it''s for a Princess, it would apply to pears also.

Maybe FG will chime in....

lol Chrono posted while I was typing!

Chrono, do you think it looks that bad?? great fancies are hard to find...

there is no such thing as an ideal pear (ideal pairs exist). This has good overall light return, but probably not great sparkliness

I would not call it bad, just "ordinary"? I can't find the right word for it. I just know that it's not bad but it's not a fiery one either.

Gary, what would untrained eyes look for to find that?

In diamonds we want more reds and blues to get stronger sparkles. For the other type a visit to the beach on a hot day.
