Which stone would you choose?

Which one would you choose?

1. An ACA whcih shows some leaks (green) under the ideal-scope
2. An AGS0 which shows virtually no leak under the ideal-scope

Assuming both stones are of the same quality ( color, carat, clarity, propoertion.. etc ) but perhaps a little premium on the ACA.

Thanks!

First, what shape?

Secondly, do you mean in an ASET?

 

[zeiss]

It''s a round shape. Yes, I was meant to say an ASET.

I'd probably get the AGS0. (non ACA)

post a link too both stones.
BTW green isn't leakage under ASET it is low angle light being returned.
Black or white depending on the setup is leakage.

I don''t have links to real stones, they are just hypothetical stones I make up in order for me to learn more what I really want.

I have browse through a few ACA & H&A stones, most of them have little white triangles beside the tip of the arrow. They appear as white in ideal-scope images and green in ASET images. (Thanks strmrdr for the correction.)

Maybe I''m not looking at high quality ACA/H&A stones?

Can someone show me ideal-scope and/or ASET images of a ''perfectly ideal'' stone?

Zeiss.

Zeiss.

those belong there, they add contrast brilliance too that area.
The only way too remove them is too paint or dig the girdle facets which affects scintillation.
