Please pass on this one. What are your specifications?

 

[bould]

Hey thanks for your response. Can you explain why you feel that you would pass on this diamond.

 

[chrono]

The ASET is almost all green, so it will not be a bright looking diamond.

Hi Bould,
There's a lot of dispute over green in the aset of a fancy cut diamond. In many cases red on a step cut aset will appear as a dark area in real life.
So green is not always a negative in an Asscher Aset
Then I also consider the steps and how apparent they are- which is an essential element of the "Asscher look".
I would advise you to look at actual photos instead of trying to get information of a reflector image which is far less intuitive.

Even smeone very experienced in reading ASET will want to physically examine the diamond to see how aset correlates with real life- it is not always consistent, especially in fancy shapes.

This goes deep into P3 angles discussion but it also covers why you want to see a certain ASET colour distribution.

GOG explains it clearly here and although the example used is a round diamond, the concept still applies to asschers.

Hi Bould,
I can not- as a trade member I am not permitted to comment on stones being sold by another vendor.

I will say with regards to the in depth linked to articles: you don't need to become a optical scientist to pick a lovely asscher cut.

All green is not good and all red is not good as well. There needs to be a balance; it is all about the quantity AND placement of these colours.

As promised you can view the ASET image for diamond 501589 attached to this email. I mentioned earlier that the gemologist confirmed this diamond is gorgeous! It is a bright, icy white that is going to look fantastic in the platinum setting. The levels of fire, brilliance and sparkle are lovely, I know your girlfriend is going to love it! The diamond has a lot of brilliance especially in the perimeter. There are no inclusions to be seen and the faceting is very uniform which yields a truly spectacular asscher cut!

From James Allen geologists and customer service....don't really k ow what to think. Are they just trying to sell the stone.

 

[chrono]

The edges "step" nicely but the center doesn't seem to come alive. The pattern, however, is very pleasing to the eye.

I guess it jives with what the JA gemmologist said, except that they did not say anything about how the center isn't "sparking" like it should. I viewed the JA diamond first, without reading the JA comment to remain unbiased or uninfluenced.

 

[bould]

Would you pay $3400 for it? Or a stone of this quality planned to have it set in platinum

 

[chrono]

How much time do you have? If it is for me, I would keep looking.

 

[bould]

Time is no issue

 

[bould]

Are there any more opinions or suggestions out there. When looking at the specs of the stones GIA report etc is this an okay purchase for $3400. The ASET is more green but there is still some red....should I pass on this as chrono suggested?
