ACA stone new line or classic???

[prober]

I was wondering if this stone was part of the new line or classic line from Whiteflash? Any other opinions on this stone would be helpful. Looks like an excellent stone scoring all ex on cut advisor

new line.
typical aca ... kicken

 

[Daniel B]

Isn''t the new line wall to wall red on the IS pic? and the the classic are cut fro contrast with whiter edges on the IS?
I have also noticed that ACA''s crown angles are always up near 38.8-38.9. . . . any reason for this?

yes on the IS
34.7/34.8/34.9 seems to be the target zone for them.

 

[peonygirl]

I''m totally unfamiliar with these terms. What do New Line and Classic mean in this context? TIA!

 

[plg_cp]

Peonygirl (and prober),

New Line and Classic Line refer to Whiteflash''s 2 different styles of cutting that either result in light return right up to the edge of the stone (like the stone prober linked to), or girdle leakage that provides more "contrast".

This is a poor explanation, so read this thread for a good explanation/discussion of both.

Mark, great link. Josh''s write-up is one I commonly refer to.

You can see the style in the ideal-scope photograph (examples below)

In general terms, ''New Line'' ACA are characterized by minimal light leakage in their ideal-scope photos. ''Classic'' ACA are characterized by slight leakage points along the girdle and at predicted meets between the table and girdle. To untrained observers the tangible differences are very slight. All ACA are cut with Visual Balance as a priority, so in terms of overall performance they''re paramount. However, after handling, studying and playing with many ACAs distinctions like these can stand out.

When customers come in they can see slight character differences, particularly once we elaborate on them.

With New Line the angles of the main crown and upper girdle facets are closer to each other, and they have a broadfire scintillation that''s been described as fluid and colorful. They tend to have a somewhat more robust look in soft lighting compared to diamonds with more contrast. Classic have more contrast. This results in a fast, sharp, on-off quality to the scintillation. The sharper dispersion is also beautiful in all illumination scenarios, with smaller flashes active in bright light conditions. For practical purposes they - along with similarly well cut diamonds - are at equal levels of craftsmanship and beauty.

Correct on the NL/Classic IS differences Daniel. A little bit offered on that above. A little more here, (painting) about the treatment you''re seeing with NL if you are interested.

As for the crown angles, it''s dependent on the overall configuration of course, but most range from 34.7-34.9 in our configs. You have been actively garnering info, so let me ask you

...With a balance of traditional diamond qualities as the prime goal, why do you think those angles are desirable?

 

[prober]

So was the original stone I posted the link for a new line or classic???????

 

[belle]

prober,
the little triangles of white in between the arrows indicate ''classic''. if you don''t see the little triangles of white in an idealscope image, the stone is new line.

 

[prober]

So I guess I will keep on looking. I want the New line ACA. Its funny though because most of ACA stones available on the site are the classic line according to the IS images. I thought the new line was replacing the classic, so why are there so many classic line still being sold??????

 

[belle]

prober,
the stone you posted IS new line. it does not have the bright white triangles between the arrows. you can compare the differences in the photos that johnq posted. new line is screen left, classic is screen right.

 

[prober]

Thanks for clarifying, thats what I originally thought. I was just confused after reading your thread. So this stone may be the one the lucky lady will get.

 

[belle]

sorry..i wasn''t trying to be confusing!

new line is not replacing classic, it is just an additional cutting style offered.
for clarification of what i was referring to, here is a grapic...

Because it will appeal to a wider range of people? I dunno?

A Sugesstion for Whiteflash/ Sir John et al.

Might be a good idea to identify on the WF website which stones are New Line fashioned and which ones aren''t.

Daniel,

Nice, safe answer.

LOL. Historically, old cut diamonds were produced with small tables and crown angles that were steep in order to produce ''fire,'' or flashes of rainbow colors. As cutting evolved (and lighting changed from gas lanterns to electric) other beautiful combinations came about in many configurations.

Brian has chosen the range above because it suits his paradigms for visual balance. They produce a nice balance of the quality of fire through many lighting conditions. A percentage are cut below, and a select few above, that range but you ID''d the preferred range.

Rockdoc

Bill, we''ve debated doing that. Right now the number of buyers who concern themselves with the difference is a small percentage of total orders, and typically only PS-types who ''get into'' the details. Clients who view the styles side by side confirm that they are at equal levels of beauty and are perfectly happy with either. Occasionally we will have a long-of-tooth enthusiast (or analyst like yourself) with a preference as a matter of taste, but it''s fractional compared to the total number going out the door.

Thanks for the input.

We are adding an overview to our FAQ you''ll be able to link.

Hi John...

Analyst? hehehe..... Maybe my eyesight is spoiled, as I do see a differnce.

I see so many really incredible stones, that maybe like you said, Maybe I''m spoiled seeing so many superbly cut stones, but I do think that is an advantage, because I do see the subtle differences that the inexperienced eye doesn''t pick up.

However, consumers that do visit here in person, I teach and once those characteristics are pointed out, they see them as well.

oh well back to playing with the pet rocks!

Just so. In person it''s possible to teach what we can''t represent on a computer screen or in pictures. More importantly, it can be seen in proper perspective.

Do you have the chameleon out? Say hi for me.

 

[RockDoc]

No actually Camille is in the Pet Rock Condo....

I have Godzilla out. He's a champagne quartz that is portuguese cut, 739 carats

Just took a photo of him.....

Rockdoc

 

[RockDoc]

Just so you can see the size comparison

Here is a 24 carat aquamarine in front of Godzilla

[JohnQuixote]

Another size comparison. Here is Macaulay Culkin in front of Godzilla.

A Pet Rock Godzilla for the "real" Godzilla

Nice how you got it to fit inside his paws..

HAHAHA What a hoot !!!!!!!!!!

I have to second Rockdoc. How difficult would it be to add one more value line / searchable factor to the website? Personally, I''d like to have the ability to search for specifically a NL or Classic, as the initial poster of this thread I''m sure would have as well. Just my 2 cents...
