Upgraded my ACA

Hello,

I bought upgraded to another ACA, but I noticed that this stone picture has more blue than other ACA's (which show no blue to very little blue reflection in their images). Is there a reason for this?

It's a 1.4 ct, E, VS1

Here are the specs:
Depth %: 61.4
Table %: 57.4
Crown Angle: 34.8
Star: 52
Pavilion Angle: 40.7
Crown %: 14.9

I'm reading on some sites that Table should be less than 57% for a super ideal. Should I be concerned?

Thank you!
 
Check the cert. Is it fluorescent?

AFAIK all ACA will grade negligible but still possible to have faint fluor.

Beautiful stone!!! I have an ACA with a 57.4 table. No concerns for me!
 
I believe @Texas Leaguer said they didn’t know why some diamonds reflect colors in the shots. I could be remembering incorrectly though...
 
No, Wewe I think you are right. Not sure colors reflected in these pictures is indicative of anything other than reflections - not that there are these colors in the stones themselves.
 
I dont think you should worry. Wait until you get it and see it in person.
 
Do you mean the areas indicated with red arrows? If so, don't worry about it. Diamonds are fundamentally mirrors. They reflect the light around them. While WF certainly does a great job controlling the lighting variables, it could be something as simple as a blue fleck on the inside of the lighting environment.

Thanks for the reply! Would a table % of 57.4 be too much? I know some people prefer less than 57.
 
This is an interesting observation. We capture this image inside a dome with diffuse LED light. Since there are no colored objects inside the dome, the blue is not a reflection. Nor is it a result of fluorescence. Instead it is a product of refraction and light that is coming from the boundaries between light and dark. You will see more or less blue (and other colors) depending on minute differences in angles and proportions, but it should not be interpreted as any kind of qualitative real life difference. It is specific to the specialized lighting environment of the dome.
A similar effect can sometimes be seen in our hearts images in the form of yellow reflections around the girdle. We see this effect usually in larger stones. Although not captured in the dome, the hearts image does also sometimes show virtual facets refracting and dispersing light into color components.
