Which would you choose? Are they worth 12000 being quoted? Should I be worried about cavity?


Please advise.


Also thank y'all for pushing me away from the egl diamond I posted earlier.

Couldn't make this purchase without y'all's expertise.

Take care

No and no. Neither of these stones is well cut. You want to stay within the following ranges for a well cut stone:

Depth no more than 62.3.

Table from 55-58.

Crown angle from 34-35.

Pavilion angle from 40.6-40.9.

The stones you've posted fall more into the 60/60 range but even those proportions are out of balance in these stones. The crown angles of 30 are very, very shallow. These will not be well cut, sparkly stones and are in no way worth $12,000 in my opinion.

Good value puts you in the color range of G/H and clarity range of VS2/SI1.

Here is a very well cut stone .10 below 1.50 - a very hard carat weight to find. It is a very well cut stone and within your price range of $12,000. http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3172030.htm?source=pricescope

Please again, read, process and study the post above and this one here:

The entire purpose of faceting a diamond is to reflect light.
How well or how poorly a diamond does this determines how beautiful it is.
How well a diamond performs is determined by the angles and cutting. This is why we say cut is king.
No other factor: not color, not clarity has as much of an impact on the appearance of a diamond as its cut. An ideal H will out white a poorly cut F. And GIA Ex is not enough. And you must stick to GIA and AGS only. EGL is a bad option: [URL='https://www.pricescope.com/community/threads/egl-certification-are-any-of-them-ok.142863/']https://www.pricescope.com/community/threads/egl-certification-are-any-of-them-ok.142863/[/URL]
So how to we ensure that we have the right angles and cutting to get the light performance we want?
https://www.pricescope.com/wiki/diamonds/diamond-cut
Well one method is to start with a GIA Ex, and then apply the HCA to it. YOU DO NOT USE HCA for AGS0 stones.
https://www.pricescope.com/wiki/diamonds/holloway-cut-advisor
The HCA is a rejection tool. Not a selection tool. It uses 4 data points to make a rudimentary call on how the diamond may perform.
If the diamond passes then you know that you are in the right zone in terms of angles for light performance. Under 2 is a pass. Under 2.5-2.1 is a maybe. 2.6 and over is a no. No score 2 and under is better than any other.
Is that enough? Not really.
So what you need is a way to check actual light performance of your actual stone.
That's what an idealscope image does. https://www.pricescope.com/wiki/diamonds/firescope-idealscope
It shows you how and wear your diamond is reflecting light, how well it is going at it, and where you are losing light return. That is why you won't see us recommending Blue Nile, as they do not provide idealscope images for their diamonds. BGD, James Allen, GOG, HPD, ERD and WF do.

The Idealscope is the 'selection tool'. Not the HCA.
So yes, with a GIA stone you need the idealscope images. Or you can buy an idealscope yourself and take it in to the jeweler you are working with to check the stones yourself. Or if you have a good return policy (full refund minimum 7 days) then you can buy the idealscope, buy the stone, and do it at home.


Now if you want to skip all that... stick to AGS0 stones and then all you have to do is pick color and clarity and you know you have a great performing diamond. Because AGS has already done the checking for you. That's why they trade at a premium
