Help - GIA VS2 RB - inclusion too visible on top?

[rosegoldandopals]

Hi all, I'm new here and have a question about the RB diamond in the link below. It is graded as a GIA VS2 and has a crystal inclusion in the table. The inclusion is clearly visible in the 360-degree view, but I believe it is at 10x magnification (although I'm not sure of this). I am not the most experienced with diamonds - would anyone be able to weigh in on whether they think this diamond would be eye clean based on its magnified image? I thought a stone graded VS2 would almost certainly look eye clean, but after poking around these forums, I have learned that that may not always be the case.

Thanks for your help!

Yeah. The inclusion is not the problem. That stone is deep at 63%. 62.4 is the deepest we recommend.

It's looking small for it's weight. And the pavilion angle is really steep.

Frankly, it's not a good stone. You need A LOT more than color and clarity to get a nice stone!

Here's what you need to know:
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 in a modern round brilliant?

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. And to keep the stones within the following specs: No deeper than 62.4, crown angle over 34% and pavilion angle 41 and under.

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.

This is a nice stone. It will be very white, completely clear of any inclusions. And B2C should be able to provide you with an image AND an ASET or Idealscope (either/or is fine).
