This is the Idealscope image of a diamond I am currently evaluating. As I see it is quite symmetrical, very good in the center but some leakage on the edges.
Any comments are welcome.

Hi JSummers,

Lovely stone. Tiny white Vs arroung the girdle are very normal and most of the diamonds will have them except EigtStar.

How did you manage to make the picture?

JSummers;

Those tiny white V's at the girdle edge are
not light leakage; rather the combination of the upper
and lower girdle facets.

I'm willing to bet this stone scores
H-3 to VH on both color light and
scintillation on the BrillianceScope.

I don't know if this is a
SuperbCert and I didn't mention anything
about facets being mis-aligned.

The point I did try to bring across
is that the proper "angle" combination
between the upper and lower girdle
halves working in concert are
significant contributors to the diamond's
colored light and scintillation.

I'm not at all certain that those very,
very tiny bits
of white light on the girdle edge
observed under the FireScope or Ideal-Scope are "leakage".

As for the picture, someone else did it, but I was told it was difficult.
This is a great site and thanks everyone:bigsmile:

Hey,

that was nice looking stone.

but taking photos with ideal scope is not difficult.

Shall I show my " high tech photo lab" and the result?

Barry, what do you think the white area around the girdle is?

He,

A pro. Hmm more like a man and Nikon. The cost of my lab ( exluding the camera) is approx $40.

$10 for the Ideal-scope
$25 for the office light
$5 for the whiter lamp .
$0 for the broken jewellery dispaly plex
$0.01 for the sheet of paper below the stone.

Sibelius;

That is really a very clever and ingenious
"photo" studio you have built.

From your picture, though, it is difficult
to see how you balance the diamond.
What does the diamond "sit" on
and how do you balance it? Is your
plexiglas clear or opaque?
Do you have any problem centering your Nikon
over the IS lens to take the picture?

Your photo is actually very good and clear.:twirl:

Also how do handle Garry's
point about holding the diamond "free"
and not placing it on a tray
so as not to get "distortion"?

It sits on a coinical hole i teh plexiclass.

Is your
plexiglas clear or opaque? clear.

Do you have any problem centering your Nikon
over the IS lens to take the picture? I check with my eye first and then I just put it on it. The camera touches the IS and I center it with gentle hands.


Thanks for asking. If you try it you will find its easy job.

hmm
Garry says its better not to have any plex. His opinion is we should observe the reality not the distorted reality.

I say we have to have steady environment for comparable results. I have no problem to use tweesers when I do not take photos but taking photos documenting information.

Photos always lie, but I try to reduce the amount of lies by following a procedure.

The same lighting, the same settings to camera the same treatment in photoshop ( crop, cut, flatten layers and so on). Also I use the plex for practical reasons.


The reading info on those photos is another issue. If I know how I have taken the photos I can compare them and results of newer photos.

Sorry Garry, I will use the plex.

Hi Garry,
I am glad you liked it:)

Did you put a $20 lens to a $10 scope?

Hi Sibelius, Garry;
Happy Holidays to you both!

What do suppose your picture would look like
with the $35 Pro-Model?

I would expect more sharp edges from facets.

While I am waiting for my pro model to arrive( Thanks GArry), you can go to nearest Nikon dealer and buy 995 Nikon coolpix. I am sure you have that much left from this season sales. :)

"Superb" advice, Sibelius.

Actually,I already purchased the Nikon-995 2 weeks ago.

It is an amazing camera!

I'll take up your suggestion and see
to take some digital shots with
your suggested set-up.

$20 and $10 lens are exactly the same - 6X. The Pro model has an additional lens making it about 10X. It is in a sexier black casing, but we still design it to be light and portable and an inexpensive tool so that all people can have access and that jewellers can take it with them for buying.
I am considering a patenting the next generation of instrument.
An inventors work is never done.
Merry Xmas to all who celebrate it and Happy everything else to everyone else (I don't like the term 'Happy Holiday')
