I would like to address an interesting
observation concerning girdle edge light leakage studies.

It has been implied by many that SuperIdeals, such as SuperbCert display
a slight leakage aroung the girdle periphery.

I believe that to be a mis-nomer...
There is clear evidence in the charts below, that point to a different conclusion...

Specifically, that these junctures, and or, meating points, located intermediately between the Arrow
blades, at the very edge of the girdle,
forming a V-type pallet, consequently, serves to enhance the scintillation factor of the diamond.

Case in point,

Hopefully, I have successfully attached
to images on this post.

1. A light scope for a 1.27ct/E/VVS2 SuperbCert. ( courtesy of GoodOldGold).

2. Brilliance scope for a 1.27/E/VVS2
SuperbCert. ( courtesy of GoodOldGold).

If you closely observe the light scope in the areas I have just described. Eight highly distinct red V-TYPE pallets will be noticed.

Now, for further corroboration. Exercise
your attentions to the LIGHT VIEW 2
position on the brilliance scope.

Here you will capture the essence of this
discussion. Notice if you will, that in the
exact same locations, an emersion of light takes place. Not just any lights, but a very distinct V-TYPE pattern of lights,
encompassing the periphery of the girdle.

For lack of better words,
peripheral spikes of light.

My 3 cent's,

Kirk

Maybe those areas are where the light from the brilliancescope allow areas of leakage to appear that they are showing light return when it is actually light from the scope leaking through.

Hi Lawmax,


Remember that those V-type spikes
are actually red in color, under the light scope, which is indicative of light return.

I see white or extremely light pink areas around the girdle. How do they look in the Firescope TM and the Ideal-Scope?

Hi lawmax;

I choose the results above for an example.

In other b-scope images you will notice
these spikes range in a multitude
of different colors...

Unless of coarse, you are not refering
to the b-scope.

Kirk,
Since I'm gathering the area you and Lawmax are speaking of are two different areas why not draw a circle around the areas your speaking about?

I have had the pleasure of knowing someone that stuffed some black tissue paper in the dome. The Vs that I'm talking about do something completely different without the back lighting from the dome. The report lets just say changed and not for the better.

If more users would post some testing/playing they have done (which we all know they have played) you may find out a few things we didn't know, or wasn't told. Not trying to start an argument, but a decent conversation with out anyone getting their feathers ruffled. I just reported what I have been told by a H&A seller maybe cutter.

Hi Steve,

The circled areas are the ones I am referring to...

There is clear indication that these V-type pallets are emitting intense light return...

Please verify by observing the light view
2 position, on the brilliance scope...

Unless you know where the light is coming from and where it goes (i.e. ray tracing) it's hard to comment on what the BS is seeing.

Are you saying that the BS is (incorrectly) showing leaked-in light as returned light?

Hi Rank,


My assertion is that, these areas
have been previously viewed upon
as a detriment, when there seems to be clear evidence of light return exactly in the areas of question.

This is why I have requested secondary
opinions from other experts.

You say there is light return, but can you be sure where the light is coming from?

Maybe the FS is correct and the BS is incorrect.

I'd call it "Very High".


p.s. Is that the same pic? I can't see any difference between the two.

I see where the arrow heads are very lively (1/2 of them anyway).

Garry;


I appreciate your comments, but
your theory of light being captured
from behind the stone has already
been addressed by the engineers
of gem-ex in there mission statements.

In other words, your theory is a variable
that has already been accounted for,
and compensated by the brilliance scope,
and the gem-ex software.

Maybe the machine didn't get a chance to read the GemEx's Mission Statement.

Hi Rank,


As a structural engineer, is it not your
priority to take every possible variable
into account?

And what if an unqualified individual,
with no structural engineering experience
whatsoever, were to challenge one of your claims?
Would you justify such a claim?

Remember, that the brilliance scope
is a devise that has been mastered by
engineers... I would not presume to
argue a case against them, unless my
credentials matched theirs.

The above argument is known in the study of Logic as "appealing to a higher authority." Basically, it claims that something is true because "someone smarter than me said so!"

Hi ESM,


Your statement is partially true,
but a result of necessity...

I seek the opinions of those whom have
a great wealth of knowledge to offer us...

Specifically;

-Jonathon
-Jasper
-Beryl
-Serg
-Garry
-Oldminer
-Rockdoc

The reason I have mentioned them by
name is because these are the heavy hitting pro's of DT... Approximately,
100 years of collective experience...

I would like to have some answers,
wouldn't you?

In addition, encouragement of a healthy debate
is good for diamond talk...
I have been respectful thus far, making valid
points when ever, or where ever, need be...

This post is purely a diamond related issue
where many can learn from...

No fluff here! just the facts please...

I haven't seen Beryl around here lately. Does anyone know what is up. Maybe he got tired of all the drama.

Hi Garry,


Lets just say that the areas in question
provide contrast...

Is it feasible that this contrast provides light return?

And if 53%, according to your studies
are indicative of light leakage in that area. Would it make further sense, that
the brilliance scope simply picks up the
47% remainder, which reflects back to you?

And if that 47% does return, is it plausible that it may assume the V-type
pattern that is found on the B-scope?

Hey Rhino,

Your said in another thread: I thought this might interest some as it's the first unbranded H&A I've ever seen with edge to edge light retention. I attached this photo as not to get buried in another thread. This seems to be a slightly different statement than you are making here.

You also said It does not prove that light is being returned where it shows leakage in the LightScope which doesn't seem to imply that there is in fact return and not leakage from elsewhere. Maybe it's me, but this doesn't seem to enhance the theory behind the Bscope.

You do later in the post say this is good or favorable. I'm a little confused, as you seem to be saying a couple different things.

Why do all the Vs not display light return? Some of the areas are very dark and some a little lighter.

Have you totally darkened the dome? I would like to know your findings against another vendor's report to me when this was done.

Good thread guys.........
